This study provides one of the most accurate estimates to date. Researchers say that women with breast implants are at risk of developing this cancer, which is called anaplastic large cell lymphoma (ALCL). ALCL is not breast cancer, but lymphoma, a cell cancer of the immune system. When a woman who is implanted with * * * * develops breast cancer, cancer cells usually appear in the scar tissue around the implant.
In the new study, the researchers estimated that the risk of breast ALCL was 65,438+0/35,000 at the age of 50, 65,438+0/65,438+02,000 at the age of 70 and 65,438+02,000 at the age of 7, despite the risks. [7 cosmetic myths revealed]
Breast augmentation and cancer for many years, researchers have realized the relationship between breast augmentation and breast ALCL development. However, there are great differences in the risk estimation of this situation. The researchers said that this new study can better estimate the risk, because it is larger than earlier studies and uses more rigorous methods.
Researchers from the Medical Center of VU University in Amsterdam identified all patients diagnosed with non-Hodgkin's lymphoma in the Netherlands, including breast cancer ALCL between 1990 and 20 16.
The researchers first examined whether breast augmentation really increased the risk of ALCL. However, because ALCL is a very rare disease, it is difficult to simply observe the incidence of ALCL in people with or without implants. On the contrary, the researchers look at this problem from another angle, starting with women who contain ALCL in * * * *, and then observing the breast augmentation rate of these women. Then, they compared this result with the implantation rate of women with other types of lymphoma in their breasts. They found that among 43 patients with breast cancer, 32 were implanted with breast cancer. In contrast, among 146 women with other breast lymphomas, only 1 had breast augmentation surgery. This means that women with breast ALCL are 42 1 times more likely to have breast augmentation surgery than women with other breast lymphomas. The researchers said that this close relationship between breast augmentation and ALCL may indicate that breast augmentation plays a role in carcinogenesis.
However, this statistic does not tell women with breast implants what the total probability of developing this disease is in their lifetime. To calculate this figure, the researchers also used the records of 3000 X-rays (which can show breast augmentation) and other information to estimate the breast augmentation rate of the Dutch population.
Researchers have determined that about 3% of Dutch women have had breast augmentation surgery. They estimate that one in every 7,000 women undergoing breast augmentation surgery has ALCL at the age of 75.
The study also found that according to the information of breast augmentation surgery types, the researchers said that 82% of ALCL women had implanted textured prostheses (not smooth prostheses), which was much higher than expected, because only about 45% of breast augmentation prostheses sold in the Netherlands were textured. This finding supplements the previous evidence that textured implants have a higher risk of ALCL than other types of implants.
How do implants cause cancer? It is not clear how implants cause ALCL. The chronic inflammation around * * * may be caused by the implant itself.
