How much does birth control increase your risk of breast cancer? Current or recent use of birth control pills (oral contraceptives) is linked to a slight increase in the risk of breast cancer [9,40-43]. Studies show while women are taking birth control pills (and shortly after), their breast cancer risk is 20-30 percent higher than for women who’ve never taken the pill [40,42-43].
Should I stop birth control if I have breast cancer? Most doctors do not advise women to use the contraceptive pill because of the possibility that the hormones might affect any remaining breast cancer cells. The withdrawal method and rhythm methods are not safe enough to prevent pregnancy.
What increases your chance of breast cancer? A woman’s risk for breast cancer is higher if she has a mother, sister, or daughter (first-degree relative) or multiple family members on either her mother’s or father’s side of the family who have had breast or ovarian cancer. Having a first-degree male relative with breast cancer also raises a woman’s risk.
What birth control increases cancer? Oral contraceptives contain human-made versions of estrogen and progesterone, so researchers think they may increase the risk of cervical and breast cancers.
