Cancer survivors can be affected by a number of health problems, but often their greatest concern is facing cancer again. If a cancer comes back after treatment it is called a recurrence. But some cancer survivors may develop a new, unrelated cancer later. This is called a second cancer. No matter what type of cancer you have had, it is still possible to get another (new) cancer, even after being treated for and surviving the first.
In fact, certain types of cancer and cancer treatments can be linked to a higher risk of certain second cancers. Since the location where a cancer of unknown primary started is not known, survivors of cancer of unknown primary can get any type of second cancer.
After completing treatment for cancer, you should still see your doctor regularly and may have tests to look for signs the cancer has come back or spread. Experts do not recommend any additional testing 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.
