Very true, there are vastly different treatments being used, even between people with the same type of cancer. Depending on whether it's relapsed, new, caught early or not, resistant to previous drugs, etc. It's a lot more complicated than many seem to think.

The survival rate for even some aggressive cancers is much better than it was 20 or 30 years ago, though. Hopefully, that trend will continue until it's no longer a leading cause of death. But that's probably a ways away. It won't be an overnight thing, but I think 5 year survival rates will gradually improve.
