Viral claims on TikTok suggest that the WHO has recently classified the contraceptive pill as a Group 1 carcinogen, similar to tobacco and alcohol. However, investigations reveal that certain contraceptive pills have been classified as carcinogenic since 2005. Only the combined pill is in Group 1, while the mini pill is in Group 2B. Studies indicate both pills may slightly increase breast cancer risk, but they can also reduce the risk of other cancers. The relationship between the pill and cancer is complex, and the claims on TikTok are misleading.
