Silimed implants are made of Polyurethane; carcinogen and mutagen
Polytech own these brands
Silimed / Sientra
All these brands produce Polyurethane implants
Government experiments with the Surgitek implants followed findings by private doctors that some of the coating
had dissolved when the implants were removed from patients. The FDA scientists, whose work on the matter
lasted for months, found similar dissolution when the implants were placed in a liquid at body temperature.
The FDA data show that the dissolution of the polyurethane begins immediately after implantation and that in some cases,
depending on factors not fully understood, the coating may dissolve almost completely within five years.
The greater the rate of dissolution, the greater the cancer risk, the scientists said they believed.
But the Surgitek spokeswoman, Karen Garoukian Ferraro, said the company's studies had brought far different results.
She said that doctors working for the company had examined 10 of the implants after they were removed from patients
and that the doctors had found that the "structural integrity of the polyurethane remains intact."
Meme implants from Bristol Myers were taken of the market due to cancer in laboratory animals.>>
However, in Europe they are still on the market !
Chemical in polyurethane implants
There is a controversial discussion about a chemical used in polyurethane implants namely 2.4 toluene diamine.
Manufacturers and plastic surgeons say: It is safe 2009 >>
Carcinogen and mutagen
According NIH Toxnet TDA is carcinogen and mutagen >>
An interesting fact: When somebody is sensitized to this substance it can not be excluded that it creates an allergic response
at very low exposure in future exposure.
Polyurethane implants cause cancer
Many women complained they experienced problems like infections and pain.
Investigators for the House panel, the Government Operations Subcommittee on Human Resources and Intergovernmental
Relations, estimate that three million American women have breast implants, and that 25 percent of all implants are
the kind that are tied to a cancer risk by the latest findings. Coated With Polyurethane
Studies of the National Cancer Institute in the early 60's showed that TDA causes cancer in one out of six test animals
In 1980, polyurethane foam introduced by Cooper Surgical as a coating for the brand Meme silicone gel implants.
Scotfoam, the supplier of polyurethane, assumed that the foam was used for industrial purposes.
"When it was observed that polyurethane-coated implants have a lower capsular contracture degree, their use became more frequent" >>
Scotfoam, the supplier of polyurethane foam discovered in 1986 for the first time that its industrial chemical was implanted
into the cancer-prone tissues of the female breast.
Scotfoam informs the firm Cooper Surgical that 2-toluene diamine (TDA), the breakdown product in foam,
is not recommended for use in human implants. If substantial amounts of TDA are produced by the chemical breakup
of the polyurethane covering of the breast implant, and then released into the blood,
the result could be an increased risk of cancer for women with implants.
Dr. Pierre Blais: 'Implants - double cancer '
Research chemist Dr. J.J.B. Pierre Blais' worked for the Canadian 'Health Protection Branch' of the Department of
National Health and Welfare, opinion and is a critic of breast implants .
Occording his opinion are the polyurethane foam used in Même implants not suitable for implantation.
Women with such implants can 'double' expect cancer. One by the silicone gel and the other by the foam.
Blais was ordered to destroy his original notes and delete the documents, wich said that polyurethane foam is not suitable for implants.
He also had his concern about the TDA and found the risks to fetuses and breast-feeding infants.
Blais was fired because he kept insisting that the polyurethane foam-coated implants should have been banned of the market. >>
Dr. Blais said that once in the body, the polyurethane coating almost immediately begin to dissolve.
Radiologist Dr. Michael S. Middleton (UC San Diego) stated that it was determined by MRI scans
that 50% of the implants were ruptured, within 10 years after implantation
In the largest cohort study on rupture of implants among 1,300 women, Dr. Michael Middleton found with a MRI an almost
100% rupture for older implants with polyurethane envelopes,
and an average rupture rate of 35% for all implants.
