There are several potential cures for various types of cancer in the human testing stage right now. It can take decades to develop those kind of things into a marketable product.
Well the thing is, "cancer" isn't a single disease and one of the problems with finding a cure for any kind of cancer, as I understand it, is that you'd be essentially inhibiting natural functions the human body needs to survive. Cancer is cell growth, they can cut out the section that's gone into overdrive if it's small enough, if it's not embedded in life-critical tissue, and IF they get it all. Course there's also chemo, which kills the cells, and unfortunately kills a bunch of healthy cells too and still isn't a cure.
As far as a cure though...the conditions that lead to cancer arise from mutations generated in DNA I think? So even if it was possible to completely cure cancer it would seem to me it would require DNA manipulation on a level we're not even close to, AND it would still have to be performed well before the tumour invades critical organs.
