What Is Plan B
Plan B is an emergency contraceptive pill containing levonorgestrel, a synthetic progestin. It is intended to prevent pregnancy after unprotected sex or contraceptive failure by delaying or inhibiting ovulation. It is not the same as the abortion pill and does not terminate an existing pregnancy.
Plan B and Cancer Risk
Current research does not show a clear link between Plan B and cancer. Hormonal contraceptives can affect certain cancer risks over time, but emergency contraception is used as a single, short-term dose. According to the American Cancer Society, there is no strong evidence that one-time levonorgestrel use meaningfully changes long-term cancer risk.
Other Health Considerations
Plan B may cause temporary side effects such as nausea, fatigue, headache, or changes in menstrual bleeding. People with certain medical conditions or those taking specific medications should consult a healthcare provider before use. For personalized guidance on cancer risk and contraception, talk to a doctor or visit the National Cancer Institute.
