Late Effects of Breast Cancer Treatment

Once breast cancer treatment ends, most side effects go away.

However, you may have some long-term side effects. And new side effects may occur months or even years after treatment ends. These long-term and new side effects may be called late effects of breast cancer treatment.

Late effects vary from person to person. So, it can be hard to plan for them and hard to cope with them.

Talk with your health care provider about any health issues you have. It may help to keep a record of side effects as they happen to track them and to discuss them with your provider. Although some conditions (such as early menopause) cannot be reversed, the symptoms can be treated.

Find a list of questions you may want to ask your health care provider about breast cancer survivorship.

“Quality of life” describes a person’s overall well-being.

Your mental and physical health (including symptoms or side effects such as pain and fatigue), ability to perform daily roles and sexual function are all part of your quality of life.

Clinical trials

Research is ongoing to improve all areas of breast cancer care, including survivorship.

After discussing the benefits and risks with your health care provider, we encourage you to consider joining a clinical trial.
