While undergoing cancer treatment, you have a lot to think about—from the affects of chemotherapy and radiation to keeping up with school and friends. And while everyone around you is probably encouraging you to rest, you may actually benefit from a healthy dose of exercise with your doctor’s permission.
We recommend that you wait at least 72 hours after chemotherapy to have sex. This is the average time it takes for the chemo to leave your system. Having sex sooner could expose your partner to the effects of chemotherapy.
Radiation therapy does not linger in the body, so there is no risk to your partner. You do not have to wait.
