Reply to comment by aiaaidan in Any type of hormonal contraceptive may increase risk of breast cancer: according to an analysis of data by researchers at Oxford, progestogen-only hormonal contraceptives may increase breast cancer risk by 20-30%; the use of combined contraceptives may also slightly increase breast cancer risk. by aiaaidan

It doesnt cause breast cancer. If a cancer is present when the patient is pregnant, it can make it grow or become clinically evident faster due to the elevated estrogen and progesterone during pregnancy.
