Counts group repeated records of the same source within each side. They do not measure evidence strength or source independence.

Is it true that hormonal birth control causes breast cancer in women?

Partly. One item reports a small excess breast cancer risk associated with long-term oral contraceptive use, mainly for one tumor subtype, while a systematic review on the question is retrieved without usable results. A separate case-control study found no statistically significant correlation between hormonal contraceptive use and breast cancer.
