Breast Cancer Survivorship: Health and Fertility After Treatment

How does breast cancer treatment affect younger women?

Women younger than age 45 years can face several health challenges after treatment for breast cancer, including the possibility of early menopause, sexual problems, and fertility problems.

How can breast cancer treatment affect my future health?

Treatment options for breast cancer can include surgery, chemotherapy, radiation therapy, and estrogen-blocking medication. In premenopausal women (those who have not yet reached natural menopause), some types of treatment can trigger early menopause symptoms. Some of these treatments also can increase the risk of certain long-term health problems.

Why does breast cancer treatment cause symptoms of menopause?

Natural menopause occurs when the ovaries stop making estrogen. Normally, this happens over a period of several years. But certain forms of breast cancer therapy, like chemotherapy, can affect the function of the ovaries. This can trigger symptoms of early menopause in premenopausal women.

Why does chemotherapy cause symptoms of menopause?

Chemotherapy can damage the ovaries. This can cause your menstrual periods to become irregular or even stop. The older you are, the more likely your periods will not return. After chemotherapy you also may experience hot flashes, vaginal dryness, urinary problems, and sleep problems.

Why does estrogen-blocking therapy cause symptoms of menopause?

Two thirds of all cases of breast cancer are estrogen-receptor positive. This means the cancer cells grow in response to estrogen. Women with estrogen-receptor positive breast cancer may take tamoxifen to stop the cancer from coming back. This medication blocks the action of estrogen in the body and sometimes causes menopause symptoms. Another type of medication, aromatase inhibitors, lowers levels of estrogen in the body. This lowering of estrogen also can cause menopause symptoms.

How can I manage menopause side effects?

Talk with your oncologist (cancer doctor), obstetrician–gynecologist (ob-gyn), or other health care professional about your cancer treatment and whether menopause symptoms are a possible side effect. Together, you can plan for safely managing side effects before they occur.

Can I take estrogen therapy for menopause symptoms?

Estrogen therapy that is given as a pill, patch, gel, or spray is called systemic therapy. With systemic therapy, estrogen is released into the bloodstream and travels to the organs and tissues where it can have a positive effect. Systemic estrogen therapy often is not recommended for breast cancer survivors. There are concerns that systemic estrogen may trigger breast cancer cells to grow and cause the cancer to come back.

Can I use vaginal estrogen for vaginal dryness?

Based on your type of cancer, you may be able to use vaginal estrogen. Vaginal estrogen comes in a cream, tablet, or ring. This therapy releases small doses of estrogen into the vagina. Unlike systemic estrogen, vaginal estrogen is absorbed by the body in very small amounts. This small, temporary increase in estrogen levels does not appear to increase the risk of breast cancer coming back. Talk with your ob-gyn to weigh the risks and benefits.

What are some nonhormonal treatments for vaginal dryness?

  • Vaginal moisturizers replace moisture of the vagina. These moisturizers do not contain hormones. There are several brands that you can buy online or at your local pharmacy.
  • Lubricants can be used when you have sexual intercourse.

What are some nonhormonal treatments for hot flashes?

  • Some lifestyle changes may help. These changes include avoiding spicy foods, alcohol, caffeine, and hot drinks; dressing in loose layers; doing breathing exercises and meditation; and getting regular exercise.
  • Cognitive behavioral therapy (CBT) has shown promise in treating hot flashes, sleep problems, and mood disturbances in women being treated for cancer.
  • Some antidepressants, antiseizure medications, and blood pressure medications may help relieve hot flashes.

What future health problems may be associated with breast cancer treatment?

Heart health. Some types of chemotherapy can increase the risk of heart disease. Estrogen-blocking medications also may increase the risk of heart disease in some women.

Bone health. Cancer treatments that reduce estrogen levels can increase the risk of osteoporosis.

Brain health. Cancer treatment can cause problems with memory, focus, and concentration.

What happens during follow-up visits with my oncologist?

Your oncologist will check your overall health and ask you about any new signs and symptoms. You may have blood tests or scans to check for cancer. Follow-up visits may become less frequent the longer you stay healthy and cancer-free.

Should I still see my ob-gyn after my breast cancer treatment?

Yes. Your ob-gyn will perform well-woman exams and screenings. You also can discuss the following with your ob-gyn:

  • Birth control methods that are safe for breast cancer survivors
  • Your sexual health and sexual satisfaction
  • Your future plans to have children
  • Possible treatment if you have difficulty getting pregnant

Should I keep seeing my primary doctor?

Yes. Your primary doctor can help you stay healthy over time. Your primary doctor can order screening tests to check other areas of your health not related to your cancer. This can include screenings for diabetes mellitus, arthritis, and other conditions that often come with aging.

What can I do to lower my risk of osteoporosis?

A test to check bone mineral density may be recommended by your ob-gyn or other health care professional. If results show that you are at increased risk of osteoporosis, medications can prevent bone loss and protect against fractures. There are things you can do to help lower your risk of fractures, including

  • increasing your intake of calcium and vitamin D
  • doing regular weight-bearing exercise
  • limiting alcohol

What can I do to lower my risk of heart disease?

Living a heart-healthy lifestyle means

  • eating a healthy diet
  • limiting alcohol
  • staying at a healthy weight
  • not smoking
  • getting daily exercise

A heart-healthy diet includes fruit, vegetables, whole grains, dairy products, and lean protein. Also, your ob-gyn or other health care professional should routinely check your blood pressure. He or she also may recommend testing for diabetes and checking your cholesterol levels.

What can I do for my brain health?

Some people have cognitive problems after chemotherapy for breast cancer. Researchers are looking at whether certain lifestyle changes can help with this common side effect, including

  • dietary changes (more fruits and vegetables, limiting fat intake)
  • getting more exercise
  • increasing social interactions
  • “brain exercises” (games and puzzles)

Even though more research is needed, it makes sense to make these changes. They may have other benefits for your health.

What should I do if I have concerns about self-image or sex after cancer?

If you have sexual concerns, the following suggestions may be helpful:

  • If you have a partner, talk with him or her about how you are feeling. An open, honest talk can lead to greater understanding about your feelings related to your cancer treatments.
  • Consider talking about your concerns with your ob-gyn or other health care professional. If you are not sure what to say, you can begin with a statement like the following:
    • —“I am having some concerns about my sex life.”
    • —“I am worried about how having cancer is affecting my sex life with my partner.”
    • —“I am feeling sad because I do not feel the same way about sex.”
    • —“How do I tell my partner that I feel unattractive since my cancer treatment?”
    • —“Sex is painful for me. What can I do?”
  • Give yourself time to adjust. Cancer treatment is a life-changing experience and may affect your self-image. If you have a partner, you may want to focus on other ways of being close rather than sexual activity.

Is it possible to have children after cancer treatment?

Chemotherapy and radiation therapy can damage the eggs inside the ovaries, resulting in infertility. For some women, this infertility is permanent. For others, pregnancy may be possible after treatment, but it may be harder to get pregnant.

What should I do if I want to have children after treatment?

If you want to have children after your breast cancer treatment, your oncologist may recommend that you take steps to preserve your fertility. One option may be to see a fertility specialist before your treatment. A fertility expert can explain your options, help you make decisions, and plan your fertility treatment before you start cancer treatment.
