Is it safe to be sexually active during cancer treatment?

Most people can be sexually active during cancer treatment, but the National Cancer Institute advises confirming this with your doctor, because it depends on your treatment and situation.

There may be times when you are advised to pause. For example, at certain points during treatment the risk of infection or bleeding can be higher, and you may be advised to avoid sexual activity then. Depending on the treatment, using a condom may be advised, because some treatments can remain in semen or vaginal secretions for a period of time. Contraception may also be advised to prevent pregnancy during treatment.

Many changes to sexual health during treatment are temporary and improve once treatment ends, while others may last longer. Related side effects such as pain, fatigue, and low mood can also affect your sex life, and speaking up about them can help you get support.

Because the right guidance depends on your specific treatment, ask your care team what is safe for you, what precautions to take, and whether there are times to avoid sexual activity. Your doctor, nurse, or a sexual health expert can answer these questions.
