Monitor for change: It's important to perform self-exams on your entire body where you look for either new lesions or changes in pre-existing lesions. Doesn't mean you're getting a skin cancer, just that you might want to have the dermatologist check. You should continue to monitor the pigmented lesions on your arm and if you notice a change in appearance of a lesion then go back to the dermatologist.

It is possible: Your dermatologist is trained in being able to detect abnormal and potentially dangerous skin lesions, including those pigmented spots. It is important to continue to follow up regularly (every 6-12 months) with the dermatologist or primary doctor for whole body skin checks. Over time your existing skin lesions can change and new lesions can develop.

Survival, but.....: Used to be, the short answer was simply survival risk with stage 1 having the best prognosis and stage IV the worst. While stages 1/2 still have the highest survival rates but improved surgical techniques and chemotherapy and i'd add lifestyle changes, have leveled the playing field greatly. Colon cancer, even advanced is often quite treatable.

It's only for some: Provenge (sipuleucel-t) is used in a very specific clinical situation with prostate cancer--definitely not indicated for everyone. The best treatment depends on the stage and grade of the cancer.

It is a complicated and very expensive treatment that has a small benefit for a very small group of patients. Most oncologist nationally use it very infrequently
