If you are diagnosed with testicle cancer, the next step is usually surgery. This means you still have to protect yourself and your partner if you are having sex . When your testicle is removed, it will be examined under a microscope to verify that it was cancerous. They will also look to see if the cancer stayed in one place or if it moved to another location. This is the big worry with cancer.
Some cancerous cells move and attack other parts of the body.
This is not good. If the doctors think the cancer has moved, the next place it would most likely be is the lymph nodes behind the abdomen. This is more serious and would require more surgery. The longer the cancerous cells sit in your testicle, the more likely that the cancer would grow and spread. This makes it harder to remove and destroy.
