Everybody has ethics and professional standards until the checkbook comes out.

Using the advanced method of guesstimating, let's assume the radius of each of the silicone spheres to be at least 20 cm. Applying V=(4/3) x pi r^3 we get a volume of 33510 cc.

You'd need a radius of 10 cm to get down to 4000 cc. This corresponds to 20 cm diameter, or rather, the length of a human hand

FWIW, we did make polypropelene ("silly-string") implants illegal. They were pulled off the market by the FDA. So there's kind of an upper-limit established.

(NSFW link) https://en.wikipedia.org/wiki/Polypropylene_breast_implant

Polypropylene implants absorb water very slowly, about <0.01% in 24 hours.[2] The polypropylene, which is yarn-like, causes irritation to the implant pocket which causes the production of serum which fills the implant pocket on a continual basis.[citation needed] This causes continuous expansion of the breast after surgery. Growth can only be alleviated by removal of serum by syringe. Problems can also arise if the breasts enlarge at different rates. This can be corrected by removal of serum or introduction of sterile saline. Continual breast growth will eventually result in "extreme, almost cartoonish breast sizes."[3]

Some do, but there will always be a surgeon somewhere who will take the money.

The only way to stop this is by regulation.

4000cc is 4 liters, and those seem way bigger than 4 liters or that person is very small.

So can someone just, you know, can they just buy those?

These might weigh 8kg each, they are not empty like a balloon, they are full of the silicone gel. Any doctor should refuse to put these on anyone.

Pretty sure these belong to the famous (infamous?) Reddit user "PumpkinSpicedBimb0"

Find their doctor for the poll.

I don't know much about implants or what they use exactly, but assuming they're liquid silicon with a density of 2.57g/cm^3^, then 4000cc would weigh 10,280g (22.67lbs). If those are EACH, then you're looking at nearly 50 pounds strapped to your chest with minimal support. Your poor back.

Most companies will refrain from producing something, but as long as there is 1 surgeon who does not feel the moral obligation to say no, they will make implants this big. Simple supply and demand. Perhaps aside from the surgeons, we should also question the implant companies if what they're doing is morally right.

Hentai tiddies?

A friend of mine wants to go bigger, but none of the doctors near her will agree to do it.

Ooooooooo woobley booblies

There will always be one that says hold my beer

Man I know of one minor celeb who want for very large breast implants (and has talked openly about her views on it very cogently) and so naively I thought "feh, people go for big titties, so what" but I checked and her implants - which look massive - are "only" 1250cc, so yeah these are mental.

I think there must be a proportion of people looking at this kind of extreme modification who have a mental illness and need help. I don't know what that proportion is, and the way that person talks about her decision convinces me completely that for her it's a niche interest like getting loads of tattoos, but... 4000cc...

I wanna slap em

I view this about the same as eyeball tattoos, ouch. Good luck have fun but I cringe a bit just looking at them. Still, kinda cool in a body horror sorta way.

look, if a woman wants to have ginormous humongous knockers, and she's willing to accept the consequences to her back for having them, then by god she should be allowed!

Bae, you sure you got enough skin to hide them under?
