The solution to cancer will be many faceted. For instance, immuno therapy works very well with some cancers. However, genetic therapy (stem cell therapy) can work well with other cancers.

Not all cancers are the same. In fact, cervical cancer has different versions of this one type. So, it isn't quite as easy as a one size fits all "cancer is cured!" but chemo therapy and radiation will be gone soon in light of a more genetics based approach.

I know this because of the long conversations I have had with my mother's oncologist.
