Sex can feel like a taboo topic for anyone, but sex and other forms of intimacy are important parts of a relationship, including for people with cancer. Cancer itself and certain treatments can have temporary or permanent physical and emotional impacts that affect a person’s sex organs, fertility, relationship with their body, ability to become aroused, and desire to want to be intimate with their partner.
Sexual health resources are available to help people living with cancer maintain an active sex life. Talking about sex and sexual intimacy with experts in Huntsman Cancer Institute’s Sexual ÐÇ¿Õ´«Ã½ and Wellbeing Clinic lets patients learn about options and what they can expect during and after treatment.
Cancer Types that Affect Sex
Engaging in sexual activity may look different for people with cancer, and that’s OK. How cancer affects a person’s sex life may depend on what type of cancer they have and the treatment they go through.
Common types of cancers that may impact sex, sex drive (libido), fertility, and body image include the following:
- Breast Cancer
- Prostate Cancer
- Leukemia
- Anal Cancer
- Reproductive cancers such as
Other forms of cancer may also impact a person’s sexual health and sex life.
Cancer Treatments that Affect Sex
Cancer treatments can affect a person’s sex life during treatment and long term. Surgery, radiation, chemotherapy, and hormone therapy are common types of treatment for cancer. Patients should ask their doctor if and how long they should wait to engage in sex after receiving certain treatments.
- Surgery may change a person’s physical appearance, sex drive, or ability to reproduce.
- Radiation to the pelvic area may cause vaginal bleeding or discomfort during sex.
- Chemotherapy and hormonal treatments can affect appearance and sex organs by reducing hormone levels. This can lead to changes in the ability to create eggs and sperm, and it may cause reactions to mucus membranes in the mouth and vagina, making sex painful. Patients should ask their doctor whether having sex raises the risk of infection.
Before Treatment
People with cancer should talk to their cancer care team before treatment begins to learn about possible outcomes and ask questions. A person’s ability to have children or become pregnant, called fertility, can be impacted by cancer and certain treatments. It is extremely important for people with cancer to talk with their doctor about fertility before cancer treatment.
Huntsman Cancer Institute works with the Utah Center for Reproductive Medicine at the University of Utah to help people with cancer who want to have children after treatment.

After Treatment
Those who have had cancer treatment may experience temporary or permanent sexual side effects. These changes can impact a person’s relationship with themselves in and outside of the bedroom and with any sexual partners.
After cancer treatment, patients should continue having follow-up visits with their cancer care team or their primary care physician for medical advice regarding their sexual health and fertility.
Pregnancy and Cancer Treatment
Pregnancy during cancer treatment can harm the fetus. It is important for those undergoing cancer treatment to use effective forms of birth control. Most doctors recommend using two methods to avoid pregnancy. Patients may not be able to use some types of birth control such as birth control pills and should talk to their care team about the best and safest methods of birth control.
Patients should also talk to their cancer care team about how long after treatment they should avoid getting pregnant. Most patients need to avoid pregnancy for six months to one year after completing cancer treatment. The time may be shorter or longer, depending on the situation.
Cancer treatment may also permanently affect one’s ability to get someone or become pregnant. For this reason, it is critical to talk about fertility before cancer treatment begins.

- Vaginal lubricants work immediately to ease dryness during sex and can be placed in and round the vagina, on penises, other body parts, or other instruments that go into the vagina. Use water- and silicone-based lubricants instead of oil-based or other products that have glycerin or flavors as these can be irritating.
- Vaginal moisturizers help to ease dryness when not having sex and should be used often, up to three times per week. Oil-based moisturizers are OK for people with no history of urinary tract infections, yeast infections, or diabetes.
- Vaginal dilators or vibrators can be used to gently stretch the vagina slowly over time and should be used with a vaginal lubricant.
For those who have had surgery for breast cancer such as mastectomy, changes associated with those surgeries may impact body image and sensations around the breast and nipple area. Nipple reconstruction, tattooing, and breast reconstruction are options that some choose following a breast cancer surgery. Keep in mind that some of these options require multiple surgeries.
