The silicon Gel is actually now a group of silicone compounds that group together forming the substance that we all know and love. The visocosity (density/fluidity) of which is lighter (and so more yeilding than saline but more viscus thus less likely to leak out. However in saying this like all fluids in bags of any discription a process called reverse osmosis occurs. This is where the concentration of a substance will automatically leach through the bag to the less concentrated area (ie into your body) Although it is less likely to occur in silicone implants, it does and when it does, the body sees this fluid as a benign growths and reacts with it, causing lumps and other horrendious problems. Saline on the other hand, when it leaks, The body sees it as seawater, and assumes it is normal bodily fluids (which is correct) and so not many problems occurs there.
So ladies with implants, do what they suggest, get them checked out at least once a year.


I do not know too much about the hormonial drugs they are currently researching, but it is being conducted in a pharmaceudical lab in Texas and probably as collaboration with other labs in the world. They going by the notion of helping Cancer patients recover from a breast removal operation, by using a cross between gene theorpy and chemical compounds to allow them to grow new breast tissue.

Some conspiracy theorists, claim that the British Government have been putting hormones into milk for the last 20 years and as such during the period the bust size of British women have jumped a cupsize from the normal upward trend. But hey we all know the British Parliment is full of Horn Dogs anyways without the theories.

Hope this Helps you Not Elvis

Silicone has a density of ~1.25 g/cm^3 (sources for figures given below), breast tissue ~1.035 g/cm^3, and human fat .94 g/cm^3.  For comparison, pure water is 1 g/cm^3.  So silicone is definitely not the same density as fat; ih fact, both saline and fat are appreciably less than silicone.

That said, while I wasn't able to find any figures for the viscosity of silicone (or rather, I was; the problem is that silicone can have a wide range of different viscosities), I suspect that the type of silicone used in breast implants has a viscosity much higher than water, creating a "feel" more like fat (which, as it exists in the human body, is semi-solid).

Breast Tissue and Silicone

Human Fat

The dangers of silicone breast implants, provided the surgery is handled well and the implants have appropriate quality control, are very ill-defined, if they exist.  Most of the evidence for any risk due to implants is due to epidemiological studies, and the epidemiological studies are far from clear.  By its nature, it's much harder to interpret epidemiological results because of the difficulty of controlling for all the variables.  That isn't to say it isn't valuable: epidemiological studies formed the beginning of the case against smoking.

The problem with breast implants is that not only are the results from epidemiology unclear, because not all studies showed effects (the typical risk looked for was an increase in autoimmune diseases, though other possibilities were explored), but that supporting evidence is lacking.  Animal studies have shown no clear biological effects from silicone.  The most serious problem, IMO, is the lack of a plausible mechanism for silicone to produce deleterious health effects.  In the case of smoking, some of the carcinogenic effects have been traced to the action of chemicals, typically oxidizers, produced in the combustion.  However, silicone is chemically inert, and as far as has been shown, biologically inactive as well.  The silicon-oxygen bonds that form in silicone are strong; it's just not a reactive chemical.

In other words, the health risks from silicone implants have been overstated.  Implants still can and do rupture, and there are other potential problems related to the interaction of the tissue in the breast with the implant, but silicone is not toxic in any meaningful way.

Zasha, sorry to cut in here but I have a question for you....you're getting unders?  Why is that?  I'm just wondering because I'm still trying to decide between the overs/unders thing.  Also, what size implants are you getting?  

Thanks:o)!!!

 If one who has been thru the implant process...now six times...counts.  I have had two set of silicone...then regrettfully the upgrades had to be saline because of the FDA in the USA.  My newest set is back to silicone and I am so happy  those manufacturers of France did not give up the fight.  Saline is much heavier and in the implant much firmer often resulting in ugly wrinkles in the skin.  Because the bags containing the saline( a true liguid) are smooth..they seldom actually adhere to the breast tissue but rather slide around the cavity. Silcone is of a "gel" consistency..thicker...more consistent.  The bags are actually textured and adhere to the inner cavity, they are very soft and move with the breast tissue..ie...  they move with you. They are considerably more comfortable to the wearer and also lighter in weight. They can also easily be placed under the muscle and result in a more natural appearance rather than a half circle planted on one's chest. When in a reclining posistion the saline implants stood upright and never moved...the silicone drop to the sides or center much like real tissue. They actually jiggle like jello when you are in motion and move with the user.  They are the next best thing to natural in my opinion and anyone who has experienced both will probably agreed.  Froms a man's point of view....well from your own opinion would you rather hold bowling ball thats cold and hard.. or something that's warm and soft and melts in your hand?

I'm going to quibble just a hair here.  100% pure silicone is indeed inert.  However, implant grade silicone is not 100% pure (close to 98% IIRC, have to look at the tube).  In addition, the silicone in implants has traditionally been a compound of several grades and compositions of silicone rather than one homgoneous strain.  There is also sufficient data that the one thing about liquid-stablized silicone is that in a very small percentage of people, it creates a nasty immune response, a very significant one in fact.  Now this is a very, very small percentage of people but it does exist.  The clinical danger with this is that silicone breaks apart into small bubbles when it goes SC so that it can be very difficult to remove all of the silicone.  That's the germ of the case against them.  However, the problem with getting up in arms about it as that there are a greater proportion of people who will be allergic to injected collagen and the linings of the darned implant bags themselves.  There is a risk but, IMHO, it's vanishingly small.

Two quick things here.  First, if my cosmetic surgeon friends aren't BS'ing me, the later silicone implants had gotten the pores down in size on the bags to the point where they were no longer permeable to the silicone and stablizing molecules even under moderate pressure.

Also, I might be being stupid here and it's been a long time since fluid dynamics but isn't that standard osmosis?  I thought that reverse osmosis was osmosis going against the concentration gradient becuase of applied pressure.

Thanks,

Hi Cinnamon!  Note the time of my earlier post here - that was some time ago.

I was on the trail to "unders" because of my very strong desire to not have them look blatantly fake.  Of course, they'll look fake enough to the trained implant observer, but the edges of the silicone implants, even overs, won't be so blatant when I rip out for competition.  It's so sad to see so many other bodybuilders that have worked so very hard on their bodies, only to ruin the overall appeal by getting a cheap augmentation.

I have since elected to have my implants placed "over," due to the unwanted placement effects (they tend to move outward - I want them right where they are) that vigorous chest excercises cause (not to mention the strange shapes that can occur).

Right now, I have 900cc max fill expanders in place (down boys!  I'm NOT going that big!!) to make room for the 750cc anatomical silicone implants.

Hi Zasha!!  Thanks so much for your reply!!  I totally understand where you're coming from - spending so much time getting your body all cut and fit, and then going and getting an augmentation to make your boobs look really fake, or cheaply done - that doesn't make too much sense!  So I see what you mean!

By the way, 750cc sili anatomicals are going to look awesome on your athletic body type!!!

Interesting though when I read the latest Guinness book of records, that the largest natural breasts are Annie Hawkins-Turner from Washington DC in USA. She has tits that  give her a bust of 70" from a 43" under bust size. That means that she wears a 52-I bra. Question is how come noone I know have heard of her or have seen a website.

Her professional name is  Norma Stitz.

Echo said it all about silicone implants.  There IS no substitute when it comes to a natural look, a natural feel, and natural movement.  PS welcome Echo - this site definitely benefits from more female input, particularly if the female has a cup size in the second half of the alphabet (your new implants are amazing!).
