The largest FDA-approved silicone breast implants available are 800 ccs.
Women who want larger breast implants than 800 ccs usually use saline implants instead of silicone because they can be filled to a much larger size.
Safely overfilling saline breast implants can increase their size by as much as 120 ccs, and other techniques can be used to produce even bigger implants.
According to Mentor’s March 2022 product catalog for example, the largest breast implants available come in sizes of between 750 and 800 cc.
The company’s largest saline-filled breast implants are 750 cc and its largest silicone gel breast implants are 800 cc.
Even larger breast implants are possible if tissue expanders are used in conjunction with breast implants, in which case you can get breast implants up to 1,250 cc.

Large breast implants have large bases
Usually, the more volume a breast implant holds, the larger its base will be as well.
At 750 ccs, breast implants with a moderate profile have about a 17 centimeter diameter (6.69 inches).
At 800 ccs, a moderate profile breast implant has a 17.6 cm diameter (6.92 in.), and a 4.4 cm height or projection off of the chest wall (1.73 in.)
High profile round breast implants of 800 ccs are about 15.4 centimeters in diameter (6.06 inches), and have a projection or height of 6.3 centimeters (2.48 inches).
Large breast implants, large problems
Breast implants are available in a wide variety of sizes to suit women of all builds and body sizes.
But using breast implants that are overly large and disproportionate to one’s body may cause big problems.
In order to accommodate the much larger breast implants, the natural breast tissue has to be stretched.
These problems can be minimized or even mostly prevented by patients who seek out very experienced breast augmentation surgeons.
As always, only the best and worst of the world makes it into the news media, but one such story is worth recounting.
The largest breast implants require multiple surgeries
In March 2022, 33-year-old model Neyleen Ashley shared that after getting the “largest legal implant size available in the U.S. [1,250 cc], she experienced a variety of physical problems that worsened each time she received larger implants.
To reach the final 1,250 cc implants, she also had to have three separate surgeries.
That’s because you can’t jump from one breast size all the way to the largest breast implant size without giving your breast tissue time to get used to each progressive new increase in size.
The massive breast implants she ended up with also cost her $17,500, she shared.
In the end, Ashley decided to have them removed and to get fat grafting to her breasts instead.
Who has the largest breast implants?
As of 2010, the woman with the largest breast implants was Texas resident and Brazilian model Sheyla Hershey.
With the largest implants in the world, Hershey’s breasts were then a size 38KKK.
Her implants used a full gallon of silicone gel to make, and reaching it required 9 separate surgeries, the last of which was done in her native Brazil after one or more U.S. plastic surgeons declined to operate on her.
In June 2021, Hershey said she’d spent $320,000 on breast augmentation surgery over the years, had a total of 39 operations on her chest, and that she nearly died four times while doing so.
Of course, not all women who want very large breasts will have to endure that many surgeries to reach their goals, nor will they have to have even one brush with death.
Sheyla Hershey once held the world record for the largest breast implants in the world. It’s unclear who does today.
Are the largest breast implants saline or silicone?
The largest FDA-approved silicone breast implants are 800 ccs.
When implants larger than 800 ccs are desired, saline is the best, most common, and usually only, solution available.
Women wishing to have larger breast implants than that will usually have a few choices:
- Use the largest breast implant size available, plus fat grafting to the breasts.
- Overfill saline breast implants beyond their “nominal fill” level to reach their recommended maximum fill (this adds as much as 120 – 175 ccs to a breast implant).
- Use the largest breast implants available in combination with a tissue flap.
There’s of course the anomaly that the aforementioned women, the model Sheyla Hershey, had larger breast implants of silicone, but that can be chalked up to the Wild West of plastic surgery in Brazil. You won’t find the same in the U.S.
Are bigger breast implants more expensive?
Breast implants aren’t usually priced based on their size, so bigger breast implants cost the same or approximately the same as implants that are a bit smaller.
But what does cost more in terms of larger breast implants is that more often than not, getting the biggest breast implants requires undergoing more than one surgical procedure.
