The Who, What, Where, When and Sometimes, Why.

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. 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 or cope with them.

Talk with your health care provider about any health issues you have. Although some conditions (such as early menopause) cannot be reversed, the symptoms can be treated.

Find a list of questions to ask your provider about breast cancer survivorship.

Quality of life after treatment

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

Your mental and physical health (including symptoms 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. 

BreastCancerTrials.org in collaboration with Susan G. Komen® offers a custom matching service to help find clinical trials that fit your health needs, including clinical trials on quality of life issues.
