A new study found that women who take birth control pills increase their risk of cervical and breast cancers.
More Research Called For
The International Agency for Research on Cancer (IARC) concluded that while birth control pills may protect against some types of cancer, they cause a higher risk for others. Birth control pills had already been considered a possible liver cancer risk.
The IARC called for more research to determine whether the total net effects were beneficial or dangerous.
Hormonal Menopausal Therapy Also Implicated
At the same time, IARC scientists looking at hormonal menopausal therapy raised its designated risk level from "possibly carcinogenic" to "carcinogenic." Hormonal menopausal therapy increases the risk of breast cancer and endometrial cancer.
About 100 million women worldwide use oral contraceptives. An additional 20 million are on hormonal menopausal therapy.
