Pancreatic and Ovarian should be near the top of the deadliest list since they are generally asymptomatic until it’s too late. Melanoma, some brain tumors because the treatment can be impractical. I would think the list drops off pretty quickly after those.
Prostate, cervical and largely colon cancer are highly treatable if one has routine checkups.
For anyone with cancer who is at the crossroads please at least research low dose naltrexone.
Also true for animals.
When the doctors thought I had ovarian cancer I was already getting ready for hospice even before surgery.
I was dumbfounded and actually pissed when it came back clear from two pathology reviews
