Sexual side effects


Many people are focused on getting healthy after a breast cancer diagnosis and might not be thinking about how cancer will affect their sex life. But it’s important to be able to have a good quality of life no matter where you are on your treatment path — and that can include being able to have a satisfying sex life.

It’s normal to lose interest in sex at times after diagnosis and during treatment. Breast cancer treatments or the cancer itself can cause fatigue, discomfort, pain, and other side effects that impact your sexual desire and activity. These side effects can happen during treatment, or months or years afterward.

It's important to know that you are not alone. LBBC has resources to help support and guide you as you manage side effects — and to help you stay connected to your sexual self.

Below, we'll talk about common breast cancer treatment side effects that can impact your sexual life. We'll also provide links to detailed information on maintaining your sexual health, getting comfortable with your body and body image, communicating with a partner, and more.


How breast cancer treatment can affect your sex life

Breast cancer treatments can cause side effects that interfere with sexual life. Some side effects are temporary and only last as long as treatment. Other side effects may be long term or start when treatment ends.

Treatment can bring up many emotions that can affect your sexuality. You may feel angry, frustrated, anxious, or guilty. Some people may feel a sense of loss for the life they had before diagnosis and treatment. These emotions are common among people living with breast cancer, and they are normal feelings to have.


Side effects that can affect sexuality

In women, specific side effects of breast cancer treatment that can affect sex life include:

In men, treatment side effects that impact sexual life can include:


Side effects by treatment type

While there are common side effects that can affect sexuality like the ones listed above, people who are being treated for breast cancer will likely encounter different side effects depending on their treatment plan. But not everyone experiences every side effect, and there are many ways to manage them if they happen. In this section, we’ll talk about the common treatments that can cause sexual side effects.


Your sex life is not over

We know that reading about side effects can be overwhelming. It's important to know that not everyone will experience all the side effects mentioned above. And no matter what kind of treatment you have, breast cancer does not mean an end to your sex life. There is a help available that can restore sexual enjoyment and intimacy.

Tips for getting back to your sex life

There are many things you can do that can help increase confidence as you ease back into sexual activity. Try to be patient with yourself. If you have a partner, be open and honest with them, and accept that your sex life now may be different than it was pre-treatment.

Other strategies include:

  • Managing vaginal dryness with vaginal moisturizers and lubricants; if non-hormonal treatments aren't helping, talk with your healthcare team about low-dose vaginal estrogen, which shows no increased risk of breast cancer death according to 2023 research published in JAMA Oncology
  • Learning about and trying new positions to ease pain you may have
  • Pelvic floor therapy to help with pain from sexual touch or penetration
  • Sex therapy to manage your response to these side effects and the impact on your relationship if you are partnered

For experienced, licensed specialists in pelvic floor therapy and sex therapy, ask your oncologist, nurse, gynecologist, or hospital social worker for a referral. There are also online resources that can help:


Getting help from your care team

As you plan treatment, talk with your care team about potential sexual side effects and any steps you can take to manage them. Many healthcare professionals are sensitive to this issue and want to help. Even if they don’t have all the answers, your doctors and nurses can direct you to other professionals who can help.

Here are some questions you can ask your care team to start a conversation about sex and sexual side effects.

  • Will my treatment affect my sex life?
  • How long will the side effects last?
  • What can I do to manage side effects?
  • How can I help my partner understand what I need?
  • Where can I get more information on how to manage side effects?

We know that it can sometimes feel uncomfortable to bring up sexual side effects with your oncologist or oncology nurse. But everyone managing a cancer diagnosis deserves to have the best quality of life they can, including a fulfilling sex life — and your care team can help. Here are some tips that might make it easier to start a conversation about your sexual concerns:

  • When you make your next oncologist appointment, mention that you would like extra time to ask questions.
  • Before your appointment, write down the symptoms you've been having, as well as any questions you have. Bring this list so you can refer to it.
  • Be as specific as you can. For example, say, “I have pain during vaginal penetration. What can I do to get relief?”
  • Rehearse what you want to say before your appointment. It can help to say the words out loud to a partner or friend, or in front of a mirror.

If your doctor or nurse is unsure how to help, or if they seem uncomfortable discussing your sexual concerns, ask for a referral to a specialist in sexual health, cancer survivorship medicine, or both. These professionals give specialized care to people who are living with the sexual side effects of cancer treatment.
