There can be no universal "cure" to cancer because cancer is a mutation of your own cells. At best, you can make targeted therapies for the most common cancer types (e.g. EGFR, KRAF, BRAS, etc.) but even these have limited efficacy.
The best way to treat cancer is to prevent it. It would be MUCH more useful to 1/ ban cigarettes 2/ tax alcohol 3/ send fat people to mandatory weight-loss camps, than spending billions on new therapies.
