Hodgkin’s lymphoma? Used to be a near-100% lethal disease of children, now has a 5-year survival in the 90%+ area - and the treatment is mostly or only chemotherapy.
Testicular cancer? Cisplatin alone took 5-year survival from 10% to the high 80%s.
Breast cancer isn’t a single disease. The HR/PR - positives do much better with hormone blockers, the triple-negatives do much better with chemo than without, many but not all HER2-positives do much better with Herceptin. And this is all compared to earlier treatment schemes, not compared to doing nothing (because that’s so much more lethal that no ethics board would let you).
But sure. It’s all bad; the industry is just hiding cures to milk patients for money; the researchers are all in their pockets, and survival isn’t getting better despite getting a lot better. (For the latter, ref the statistics from the Norwegian cancer registry, at http://www.kreftregisteret.no/en/General/News/Cancer-in-Norway-2011/ ).
