My advice is to take a look at the natural things that can help prevent cancer from ever happening, beat it if you get it and prevent it from coming back once you beat it.
Tumors, cysts, skin cancers and other cancerous cell masses are the symptoms of an underlying cause that enabled cancer to get past your natural first line of defense and gain a foothold in the first place. Most likely, a less than optimum immune system as well as a liver that is less than 100% is also involved, as is the likely presence of toxins and/or pathogens.
To understand what nature may have to offer, and the benefits of a healthy diet, lifestyle, exercise, pure water, proper nutrition, removal of stress and, believe it or not, and sunshine* can do, take a look at:

*Yes, ironically, while excessive sun is a primary contributor to melanoma and other skin cancers, evidence suggests that adequate sunshine is one of the best protectors against future melanoma.
