The conversation about implant size usually opens with a bra. A patient is a 34B and wants to be a C, or she wears a 36C now and wants a full D. It feels like a precise request, and it is almost useless as a surgical instruction. Bra sizes are retail labels. A 34C in one brand fits like a 34B in another, and cup volume changes with the band size, so a 32D and a 38B can hold similar amounts of tissue. Nothing about a bra letter tells a surgeon how wide the chest is, how much breast tissue sits on top of it, or how the skin will respond to a new volume underneath.
Dr. John Ayala, a board certified plastic surgeon in San Antonio, tends to move the conversation away from letters early. The decision is really three decisions made in sequence. How wide should the implant be, to suit the chest it sits on? How much volume should it add? And how far forward should it project? Each answer limits the next one, and the fill material, the pocket, and the incision are layered on top. This guide goes deeper than the practice's main breast augmentation page, taking the decisions in the order a surgeon works through them and explains why each one matters for a result that looks natural and holds up over time.
Start with the chest wall, because the implant has to live on it
The first measurement that matters has nothing to do with the breast. It is the width of the chest wall where the breast sits, called the base width. Every implant has a base diameter, and the best fit usually lies close to the patient's own breast base. An implant that is too wide for a narrow chest spills past the edge of the breast toward the armpit, and it tends to look fake from the side. An implant that is too narrow for a wide chest can leave an awkward gap in the cleavage and a rounded appearance that does not fill the space.
The second input is the tissue already present. A patient with very little breast tissue and thin skin has a thin cushion over the implant. The edges of the implant may be visible or palpable, and rippling can show up in the upper pole. A patient with a fuller breast has more natural coverage, and the same implant looks softer and less obvious. This is one reason the same implant looks different in two people and why a photo of someone else's result is a poor guide to your own.
A third input is skin quality and nipple position. If the skin is lax or the nipple sits at or below the crease beneath the breast, an implant by itself will increase fullness but not correct the droop. In those patients, the discussion turns toward a lift, or a lift combined with an implant, and Ayala Plastic Surgery's guide to breast lift with augmentation is the place to read about when that second step is needed.
Finally, chest shape matters. A pronounced rib flare, a sunken breastbone, or natural asymmetry between the two sides will show through an implant, and the surgeon has to plan around them. Perfect symmetry is not the usual starting point for anyone, and a good plan accounts for that from the beginning instead of promising a match that anatomy will not allow. One breast is often a little larger than the other, one nipple sits a little higher, and one side of the rib cage may be more prominent. Sometimes the plan uses slightly different implant volumes on the two sides to balance the result, and patients should hear that possibility before surgery, not discover it afterward.
A simple clinical check illustrates why tissue thickness matters so much. When the surgeon gently pinches the skin and breast tissue at the upper part of the breast, away from the fold, the thickness between the fingers gives a rough measure of how much natural coverage exists. A pinch of an inch or more suggests enough tissue to hide an implant in most positions. A thin pinch suggests the implant will sit close to the surface, and it points toward placing the implant partly beneath the muscle and choosing a fill that feels soft.
The three numbers behind every implant: width, volume and projection
Once the chest has been measured, the implant itself can be described using three numbers.
Width is the diameter of the base. It is chosen to match the chest and breast, as described above.
Volume is measured in cubic centimeters, or cc. It tells how much material is in the implant, and it is the number patients usually hear about. Volume is a result of the other two. A wider implant with low projection and a narrower one with high projection can hold the same cc and look completely different on the body.
Projection, or profile, is how far the implant extends forward from the chest. Implants come in profiles that range from low through moderate to high and beyond. A higher profile gives more forward fullness in the same width, and it creates a rounder, more pronounced upper breast. A lower profile spreads volume across the width, which looks more gradual and more like a natural slope.
This is where cc comparisons between patients mislead. Two women can both have 350 cc implants and look very different because one has a wide chest and a moderate profile while the other has a narrow chest and a high one. The better conversation is about the look that the width and projection together will produce on a particular frame, with volume following from that decision. Price depends on implant type, incision and overall complexity instead of on cc alone, and the practice keeps a separate breast augmentation cost page for readers who want that detail.
Ayala Plastic Surgery's guidance on volume is simple and practical. About 200 cc corresponds roughly to one cup size, with the caveat that bra brands vary. That rule of thumb is helpful for orientation and nothing more.
What implant weight does to a body over time
Volume carries weight, and weight has consequences that matter more in year ten than in month one. Breast implants weigh about 0.21 pounds per 100 cc, so a typical pair of 300 to 400 cc implants adds roughly a pound and a half in total. That is not a heavy load. But the load is borne by breast tissue and skin that continue to age, and larger implants stress them more.
Over many years, a heavy implant can stretch the lower pole of the breast, push the implant lower on the chest wall and accelerate sagging. The tissue thins under the implant, which can make edges more visible and increase the chance of needing a revision. Patients who want a large result should understand this trade-off rather than treating the largest comfortable size as the default. A modest size that the tissue can support comfortably often ages better than a size at the limit of what the chest can carry.
For active patients, the practical consequences are different. A very large implant can feel cumbersome during running or other impact exercise, while a moderate implant is often forgotten by the second month. That detail seldom comes up on intake forms, and it is worth stating out loud during a consultation.
Why the same implant behaves differently at 25, 35 and 45
Skin is the part of the system that changes most with age and life events, and it is the part no implant can supply. At twenty-five, skin is usually elastic, it contracts around a new volume and holds the breast high on the chest. At thirty-five, after one or two pregnancies and years of hormone shifts, the skin may have lost some of that recoil, and the same implant sits lower and looks less perky. At forty-five or fifty, the combination of thinner tissue and lower skin tone makes lifting more likely to be part of the plan.
Pregnancy and breastfeeding add their own changes. The breast enlarges, the skin stretches, and afterward volume often shrinks and settles lower than before. Patients in this group often ask for a result that restores what they had at twenty-five, and the honest answer is that implants restore volume while skin tone determines position. That is why many patients in their thirties and forties find themselves reading about a mommy makeover, in which breast work is paired with abdominal contouring under one anesthetic and one recovery.
Weight is the other variable. A change of fifteen or twenty pounds alters the fullness of the breast and the way an implant sits within it, so patients who expect large swings should plan the timing carefully. The practice's article on gaining weight after a mommy makeover addresses how weight fluctuation affects results after body contouring, and the same principle applies to the breasts.
The try-on session: using a sizing bra to translate numbers into a look
The try-on is run by the practice's team together with Dr. Ayala, which means the person helping with the bra is also the person who will answer questions after surgery.
At Ayala Plastic Surgery, patients can try on different implant sizes with a special bra during the consultation, which turns abstract cc numbers into something visible. The value of this step is hard to overstate, because it shows how a volume looks in clothing, how a profile changes the silhouette and how much difference a hundred cc really makes.
A few habits make a sizing session more reliable. Wear a fitted top, since a loose shirt hides shape. Bring the clothes you wear most often, including workout wear and something dressy, since a size that looks great in a tank top may look overwhelming in a fitted dress. Bring two or three photos of results you like, and be ready to talk about why you like them. A photograph of a result on a similar frame is a much better guide than a photograph of a result on a very different body.
Try-on sizers have a limit, which is that they sit on top of the breast instead of inside the tissue. They are a guide to proportion, not a precise simulation. The surgeon's judgment about width, tissue and projection fills the gap between a trial in a bra and a final result under skin and muscle.
Saline or silicone: what actually differs
Two fill types are available at Ayala Plastic Surgery. Both have a silicone outer shell. Saline implants are filled with sterile salt water. Silicone implants are filled with a cohesive silicone gel.
The differences that matter in daily life are feel, behavior if the implant leaks, and detection.
On feel, many patients and surgeons find silicone gel closer to natural breast tissue, particularly in patients with thinner coverage. Saline can feel firmer and sometimes more prone to visible rippling in thin patients, though a well-planned pocket and adequate coverage reduce that.
On leakage, the behavior differs. If a saline implant ruptures, the shell deflates over a short time, the breast loses volume visibly, and the body absorbs the saline harmlessly. Detection is obvious. If a silicone implant develops a tear, the gel in modern implants generally stays within or near the capsule, and the breast may look and feel unchanged. This is sometimes called a silent rupture, and it is the reason the FDA recommends periodic imaging, with an MRI or ultrasound at about five to six years after placement and every two to three years thereafter, for patients with silicone gel implants. Patients should ask the office about the screening schedule and plan for it as part of ownership.
On regulatory approval, saline implants are FDA approved for patients who are 18 or older for cosmetic augmentation, while silicone gel implants are approved for patients who are 22 or older. Reconstruction patients of any age may receive either.
Silicone gel itself has changed. Modern implants use a cohesive gel that holds together much like a soft solid, so a tear does not release a runny liquid, and the shell is built in several layers to resist wear. Saline implants have a valve through which the surgeon fills the implant once it is in the pocket, which allows the volume to be fine-tuned during surgery and permits a smaller incision. Each design reflects a decade of refinement, and neither has stood still.
The choice is rarely about one fill being better. It is about which set of trade-offs suits a patient. A patient with thin coverage and a strong preference for a natural feel may lean toward silicone and accept the imaging commitment. A patient who prefers the simplicity of detecting a leak by sight, or who is under 22, may lean toward saline.
Above or below the muscle: how placement changes both the look and the long-term risk
Placement of the implant relative to the chest muscle is one of the biggest decisions in a breast augmentation, and it affects how the result looks, how it feels and how likely certain complications are.
In the subglandular position, the implant sits on top of the chest muscle and beneath the breast tissue. It requires enough natural tissue and skin to cover it, because thin skin leads to a higher chance of visible rippling. In the submuscular position, the implant sits at least partly beneath the pectoral muscle. According to Ayala Plastic Surgery, submuscular placement offers more coverage, reduces visible edges, gives more reliable mammography and lowers the risk of capsular contracture, the firm scar tissue that can form around an implant and one of the main reasons for implant revision.
Submuscular placement has its own trade-offs. In some patients, flexing the chest muscle can shift the implant, an effect called animation. Recovery can feel tighter in the first days because the muscle has been separated from the chest wall. A dual plane approach, in which part of the implant sits beneath the muscle and part beneath the breast tissue, is used by many surgeons to balance these factors, and the specifics depend on anatomy.
For most patients with limited natural tissue, submuscular placement is the more forgiving choice. For patients with a fuller breast and a preference to avoid muscle movement, the subglandular option may be reasonable. The decision should be made on the exam, not on a general rule.
The incision question: three doors to the same pocket
Three incision locations are commonly offered, and each has a different balance of access, visibility and flexibility.
The inframammary incision is made along the crease beneath the breast. It is versatile, works for any implant type or size and gives the surgeon direct control of the pocket. The scar sits in the fold, where it is usually well hidden.
The periareolar incision runs along the lower border of the areola, where the pigment change camouflages the scar. It is best suited to smaller implants, because the opening is limited by the size of the areola.
The transaxillary incision is made in a fold of the armpit and leaves no scar on the breast. According to Ayala Plastic Surgery, it is used with saline implants only.
A patient's preference about visible scars is a legitimate input, and anyone curious about how scars mature and what can be done if one heals poorly can read about scar revision at the practice. The preference should be weighed against what each route can safely achieve. A surgeon who is uncomfortable with a given approach for a given implant should say so plainly.
Whichever door is chosen, the operation takes place in an accredited surgical center under general anesthesia, and patients recover under nurse supervision before going home. The team at the office handles the pre-operative instructions and follow-up visits, so the person who answers questions after surgery is someone the patient has already met.
When an implant is the wrong tool for the problem
Not every patient who asks for implants is a candidate for implants alone. Three situations come up regularly.
Sagging that has gone beyond what an implant can lift is the first. Adding volume to a breast with a low nipple position can create a fuller but still drooping breast, and sometimes accentuates the sag. A lift or a combined procedure may be the better path. Ayala Plastic Surgery's breast lift page describes how a lift repositions tissue and reshapes the breast.
Modest volume loss with good position is the second. Some patients are happy with a small increase in size and do not need a large implant. Fat transfer is sometimes proposed for these patients as a natural alternative, though the existing page on the topic notes that it produces only a mild volume increase, and non-surgical breast augmentation is not available at the practice.
Areola concerns are the third. Some patients are bothered less by size than by proportions, with areolas that look large or mismatched in relation to the breast. A short article on areola reduction explains when that is a separate decision and when it can be coordinated with augmentation or a lift.
What the first weeks of recovery actually look like
Recovery from breast augmentation is more predictable than most patients expect, and the milestones are specific. According to the practice, a friend or relative must drive the patient home and stay for the first 24 hours. A surgical or non-underwire bra is worn for at least two weeks. Most patients return to work within about a week, although they should avoid heavy lifting for two to three weeks and vigorous exercise for three to four weeks. Driving is generally off the table for at least three days. Swimming waits until the incisions have healed, which is about ten days. Most patients feel back to normal within three to four weeks, and final results are generally visible at around one year, since implants settle and swelling resolves gradually.
The first week is when the breasts sit high and tight, and sometimes look unnaturally round. That appearance is expected. Implants drop and soften as the pocket relaxes and swelling subsides, and many patients are encouraged by the change between week two and week six. Those who want a look at how healing unfolds after any procedure can read the practice's week by week recovery timeline.
Pregnancy, breastfeeding and the long view
Plans for the future belong in the planning stage. Breastfeeding is generally possible after augmentation, but pregnancy-related changes in size and shape can alter the result, so patients who expect to have children soon should discuss timing. Some choose to wait until their family is complete, while others proceed and accept that a lift or revision may be needed later.
Implants are not lifetime devices. They can be a very long-term investment, but complications such as capsular contracture, rupture, rippling or changes in breast shape may appear years later, and some patients simply decide they want a different size. Ayala Plastic Surgery offers revision work for rupture, capsular contracture and results from prior surgeons, and the practice's guide to implant revision in San Antonio covers removal, replacement and capsular contracture treatment in detail.
Weight changes affect results, too. Significant weight gain or loss changes the soft tissue around the implant and can change the shape of the breast. Patients who plan to lose a large amount of weight should consider timing. For patients who are combining breast work with abdominal surgery after children, the practice's mommy makeover page explains how procedures are sequenced.
Safety topics every implant patient should hear plainly
Three safety conversations belong in every consultation, and a trustworthy surgeon raises them without being asked.
The first is the rare lymphoma known as breast implant associated anaplastic large cell lymphoma. It has been linked mainly to textured implant surfaces and is uncommon, but patients should know the term and the typical presentation, usually late swelling or fluid around the implant.
The second is capsular contracture, in which the scar tissue around the implant tightens and can cause firmness, distortion or pain. It is one of the more common reasons for revision. Placement under the muscle and careful technique lower the risk, though they do not eliminate it.
The third is patient-reported symptoms sometimes described as breast implant illness. Research has not established a clear causal link, and patients experiencing such symptoms deserve to be taken seriously and evaluated. Since 2021, the FDA has required a boxed warning and a patient decision checklist for breast implants, and patients should expect to review that checklist together with the surgeon and sign it before surgery.
None of these topics should be a reason to avoid the operation if it is right for the patient. They are reasons to choose a surgeon who discusses them directly and a practice that supports long-term follow-up. Dr. Ayala's credentials as a board certified plastic surgeon and Fellow of the American College of Surgeons are laid out on his biography page for patients who want to confirm them.
How to read before and after photos for implant planning
Before and after images are the most useful research tool and the most frequently misread. A few habits make them more informative.
Compare chest width and frame, not only the cup. A result on a narrow, athletic frame tells you little about a result on a wider one. Look at the same angles before and after. Front views alone hide projection, and side views show how natural or round the slope looks. Notice the upper pole fullness and the cleavage. A very full upper pole often means a high profile or a wide implant on a small frame, and some patients love that look while others prefer a gentler slope.
Look for patients whose starting anatomy resembles yours. The practice's breast augmentation gallery is a good place to start. Notice whether the nipples sit centered on the new breast, and whether the two sides appear balanced with each other. Perfect symmetry rarely exists, but a plan should visibly aim for it.
Cost naturally enters the research process too. Because price depends on implant type, incision, complexity and whether revision is involved, the practice maintains a separate cost page.
A consultation checklist that keeps the decision on track
A productive implant consultation answers a short list of questions, and it helps to walk in with them written down.
What are the measurements of my chest and breasts, and how do they shape the choice of width? What range of volumes and profiles fits my frame, and what does each look like on me? Which fill do you recommend for my tissue, and why? Above or below the muscle, and what are the trade-offs for my anatomy? Which incision suits my implant choice and my scar preferences? What does recovery look like for my job and my household? What follow-up and imaging will I need over the long term? What happens if I am unhappy with the size?
Reading what other patients say about the experience helps too, and the practice's online reviews page collects them in one place. Patients with young children should know about the practice's no-children policy in the office, which means arranging childcare for consultations and visits. Anyone ready to begin can schedule an appointment and bring photos, a few favorite outfits and the list of questions above.
Frequently Asked Questions
How do I choose the right breast implant size?
Start with chest width, existing breast tissue and skin quality, then try on sizers in a sizing bra. Width, volume and projection are chosen together, because the same volume can look very different on different frames.
How many cc equals one cup size?
About 200 cc is often cited as roughly one cup size, although bra sizes vary by brand and band size. It is a rough orientation and not a precise rule.
Are silicone or saline implants better?
Neither is universally better. Silicone gel often feels closer to natural tissue, while saline makes a leak easy to detect. Saline is approved from age 18 and silicone from age 22 for cosmetic augmentation.
Do silicone implants need to be checked?
The FDA recommends periodic imaging, usually an MRI or ultrasound at about five to six years and every two to three years after that, because silicone leaks can be silent.
Should implants go over or under the muscle?
Under the muscle offers more coverage, hides edges, supports more reliable mammography and lowers capsular contracture risk. Over the muscle requires enough natural tissue and skin to avoid rippling. The right choice depends on the exam.
Which breast augmentation incision is best?
The inframammary incision in the breast crease works for any implant. The periareolar incision suits smaller implants, and the armpit route is used with saline implants only. Scar preference and anatomy guide the choice.
How long is recovery after breast augmentation?
Most patients return to work within about a week, avoid heavy lifting for two to three weeks and wait three to four weeks for vigorous exercise. Most feel back to normal in three to four weeks, and final results appear around one year.
Can I breastfeed with breast implants?
Breastfeeding is generally possible after augmentation. Because pregnancy can change breast size and shape, patients who plan to have children soon should discuss timing with the surgeon.
Do breast implants last forever?
No. Implants are long-term devices, not lifetime ones. Complications such as rupture, capsular contracture or shape changes can appear years later, and some patients choose a revision for a different size.
How much do breast implants weigh?
Implants weigh about 0.21 pounds per 100 cc, so a typical pair of 300 to 400 cc implants adds roughly one and a half pounds in total.
Can an implant fix sagging breasts?
Usually not by itself. If the nipple sits low or the skin is lax, a lift or a combined lift and implant procedure often gives a better result than an implant alone.
Is non-surgical breast augmentation an option?
Not at this practice. Implants are the most effective and long-lasting option, and fat transfer gives only a mild increase in volume.
