Why such a strong push to cure cancer?

Why is it more important than any other cancer of the body, like lung cancer, colon cancer, brain cancer, pancreatic cancer, etc., or any other diseases like MS, Alzheimer's, Cerebral Palsy, etc? It's like everywhere I go I see pink ribbons and "cure cancer" marketing. It's push to cure it is so incredibly disproportionate as to make me think there is some political motive behind it. Could it have something to do with the fact that abortion can cause cancer? That would certainly provide a political motive.
