This summary table contains detailed information about research studies. Summary tables are a useful way to look at the science behind many breast cancer guidelines and recommendations. However, to get the most out of the tables, it’s important to understand some key concepts. Learn how to read a research table.
Introduction: Neither saline nor silicone breast implants appear to increase breast cancer risk. A meta-analysis that combined the results from 10 studies found no increase in breast cancer risk among women with breast implants .
A few studies in the table below found a lower risk of breast cancer among women with implants. However, this is likely due to traits of women who tend to choose breast implants (such as being lean), rather than the implants themselves .

Anaplastic large cell lymphoma (ALCL) is a very rare cancer of the cells of the immune system [3-5]. When ALCL occurs in women with breast implants it’s called breast implant-associated ALCL (BIA-ALCL). BIA-ALCL is treatable.
Estimates of the risk of BIA-ALCL occurring in women with breast implants vary widely from 1 in 3,817 to 1 in 30,000 . These estimates are based on confirmed cases known at this time .
The Food and Drug Administration (FDA) is studying the link between breast implants (both saline and silicone) and a slight increased risk of BIA-ALCL .
Although the reasons are unclear at this time, the risk of BIA-ALCL appears to be linked to textured breast implants rather than smooth implants [3-6].
Talk with your health care provider about the benefits and risks of textured implants and smooth implants.
Let your provider know if you notice any changes to your implant(s) or any pain in the area.
Learn about the strengths and weaknesses of different types of studies. See how this risk factor compares with other risk factors for breast cancer.
Study selection criteria: Prospective cohort studies with at least 40 breast cancer cases and meta-analyses.
Table note: The standardized incidence ratios below compare the incidence of breast cancer among women with breast implants to incidence in the general population.
A standardized incidence ratio above 1 shows an increased risk among women with breast implants. A standardized incidence ratio below 1 shows a decreased risk.
