Because prostate tumors often grow slowly or not at all, they might not be harmful enough to need treatment. Some men decide -- with their doctors -- that "watchful waiting" or "active surveillance" are better options than surgery, chemo, or radiation. This approach means you’ll keep close track of the cancer with tests, biopsies, and regular doctor's visits to see if it gets worse. Research has shown that these can be safe options for many men. If the tumor starts to grow or if you're not comfortable with "doing nothing," talk with your doctor about moving forward with treatment.
