It's not as great as you might think, despite all the stories you see like this one. That's because most of the stories are in cells (this one) or mice.

The big success story, about 20 years old now, is testicular cancer. You can have metastatic testicular cancer with tumors all over your body (like Lance Armstrong had) and they can cure it. They use platinum based chemotherapy and it's not really well understood why it works for testicular cancer, but not others.

The story with childhood leukemias is similar. They figured out how to combine a bunch of chemotherapy to get the cure rate up pretty high. Leukemia in a child used to be (1990s) 90% fatal, it's like 10% now.

Besides those, most of the advances in the past few decades come from early detection/ surgery or just prevention (stop smoking).

There is some hope though. When people first started studying cancers at the molecular level, one of the first things they noticed was how often a gene called Ras was mutated in different cancers. It turns out that designing a drug for Ras was really hard, but it finally got done, it's called daraxonrasib. They just released phase III human trials with this drug in pancreatic cancer a week or two ago and it destroyed the standard of care (Chemotherapy), but that is saying people who were dying in 1-2 months were still alive after 5-6 months.

The former senator Ben Sasse was diagnosed with metastatic pancreatic cancer last December. Historically, that's like 5% survival rate for 5 years. He is on daraxonrasib. We will see how it works out.
