Does a cancer recurrence mean my first treatment was wrong?

No. A recurrence does not mean the treatment you received was wrong.

Recurrent cancer starts with cancer cells that the first treatment did not fully remove or destroy. It simply means a small number of cancer cells survived the treatment and were too small to show up in follow-up tests. Over time, those cells grew into tumors or cancer that your doctor can now detect.

It is natural to feel shock, anger, sadness, or fear when cancer comes back. But you have experience now that you did not have before. Treatments may also have improved since your first cancer, and there are many treatment choices to consider. Your health care team can explain why the cancer returned and what options may help.
