Breast cancer survivors can be affected by a number of health problems, but often a major concern is facing cancer again. Cancer that comes back after treatment is called a recurrence. But some cancer survivors develop a new, unrelated cancer later. This is called a second cancer.
Men who have had breast cancer can get any type of second cancer, but they have a higher increased risk for certain types of cancer, including:
For some second cancers, shared genetic risk factors may play a role. For example, men with mutations in the BRCA2 gene have an increased risk of prostate and pancreas cancer as well as breast cancer. All men with breast cancer meet guidelines for genetic testing and should discuss this with their doctor or see a genetic counselor.
After completing treatment for breast cancer, you should still see your doctor regularly to look for signs the cancer has come back or spread. Experts do not recommend any specific tests to look for second cancers in patients without symptoms. Let your doctor know about any new symptoms or problems, because they could be caused by the cancer coming back or by a new disease or second cancer.
