Silicone breast implants increase the risk of arthritis by 600%, risk of fetal death by 450% and skin cancer by 400%, according to a study.
Compared to physiological implants, women with silicone implants are twice as likely to have surgical complications, especially scars around the implant.
The team at the MD Anderson Cancer Development Center at the University of Texas at Houston said their research was the largest of the breast implant results so far and that the findings are important to help women choose the implant that they think fit.
The most popular implants approved by the American Food and Drug Administration (FDA) are silicone implants and implants filled with physiological saline.
Silicone implants use plastic gel-filled envelopes, while physiological implants use silicone envelopes filled with sterile saline.
For reconstruction of the breast and both implants are approved for women of all ages.
Breast augmentation, which aims to increase the size or change the shape of the breast, has been approved for physiological implants for women over and above 18 years of age and approved silicone implants for women aged 22 or older.
Many women say that silicone implants look more like real breasts than salmon implants, but they pose a greater risk.
In the early 1990s the FDA banned silicone implants after several health problems related to their relationship to cancer risk, connective tissue disease and autoimmune diseases.
No study has established a definitive link between silicone implants and these conditions.
Since the silicone implants from two manufacturers were approved in 2006, the FDA has conducted many approval studies, but no investigator has analyzed the database.
For the new study published in Surgery Analyzes, the team examined nearly 100,000 patients enrolled in large studies after approval between 2007 and 2010.
Approximately 80,000 had silicone implants, and the rest received implants filled with saline.
In addition, 72 percent of women had breast augmentation, 15 percent increased the revision, 10 percent had breast reconstruction, and 3 percent were re-examined.
Researchers found that women who have silicone implants are at higher risk of several rare side effects.
This includes rheumatoid arthritis; Sjogren's syndrome, an immune system disorder characterized by dry eye and dry mouth; and scleroderma, chronic cure and stretching of the skin and connective tissue.
All these conditions have six to eight times higher risk in these women than in the general population.
Women with silicone implants also have a 4.5 times greater risk of having a birth but not by miscarriage.
Researchers also found that women with silicone implants had a risk of developing melanoma, which was four times higher.
Silicon implants are also associated with an increased risk of surgical complications compared to saline solutions.
About five percent of women had scarring around the implant, known as capsular contracture, compared with 2.8% of women with salt implants.
"We report an analysis of the largest prospective study so far on the safety of silicone breast implants," said Dr. Mark Clemens, Associate Professor of Plastic Surgery at MD Anderson Cancer Center.
"We share critical information about levels of complications and rare associations with systemic disabilities." These data provide women with important information about the safety of silicone breast implants in order to have realistic expectations and help them choose the best for them.
The authors note that although some risks are more common in women with silicone implants, "the absolute frequency of these side effects is low."
"Women should not be panicked, but what they tell us is that something is happening and is different from what women have said over the past two decades," says Diana Zukerman, president of DailyMail. of the National Center for Health Research. COM
"There is still cause for concern and we must think that all these increased risks are gaining." "Not all women have all these diseases, but some are unanimous, and others are against others that can be statistically different."
