Cancer is not a single diseases, it’s many. And yes, many types of cancer can be treated successfully today, people’s lives are saved, and new, functioning drugs are created constantly. Progress is HUGE.

? There's advances all the time.

You probably live in some sort of a bubble as there's news about new medications and treatments more than ever.

You should look into the cancer vaccine.

Basically it’s a therapeutic vaccine (like rabies vax, it’s given after you’ve got the problem), that tells your body that specific cancer cells are foreign invaders. I don’t know a whole lot about it, and my info is somewhat outdated, so I’ll be reviewing the info I’m linking more closely when I have more time. There are also some prophylactic, or preventative, like the HPV vax, which is obviously the end goal but not necessarily possible for all cancers.

It is still in progress, and often, from what I understand, needs to be made for each patient and the specific cancer cells they are growing, but if it works for wherever they try it on, there’s your cure.

Below you’ll find some citations but bear in mind this is a pretty new development.

Because you don't look for it, you don't find it. Little advancements don't make it to general news outlets. When you hear big news like that doctor that cured pancreatic cancer, you can assume it's being blown out of proportion until proven otherwise.

Every time you hear that they developed a drug that selectively kills cancer cells in vitro, that's an incremental step. When you hear that someone successfully cured a specific type of cancer in rats, that's an incremental step.
