14 Researchers did find TDA in the urine, but in such tiny amounts that the risk of cancer from the polyurethane foam-coated implants is only about l in a million over a woman's lifetime. It is also not known what effect implants have on lactation, and whether or not there is a difference in the rate of implant rupture, breast pain, migration of the implant, or mastitis in women who are pregnant or lactating. There is one inconclusive report that describes eight children breast fed by women with silicone breast implants. These children experienced abdominal pain and swallowing problems. However, it is not known if the problems of these children are related to their mother's breast implants.
Further study is needed.
At least some women with breast augmentation are able to nurse their babies. A woman who has had a mastectomy is unable to breast-feed on the affected side due to loss of breast tissue and glands that produce milk. A woman with breast implants who has questions about risks while pregnant or breastfeeding should consult her doctor. A woman who suspects that an adverse event experienced by her child may be related to her breast implants should report this information to her doctor. Suspected serious adverse events should be reported to FDA's MedWatch program.
