If it makes your feel any better, scientists have made some outstanding research and are not far off a comprehensive cure for certain cancers, they've created a drug that effectively reboots the immune system allowing it to target cancer cells instead of being suppressed. As well as that even the most inaccessible brain tumors (often the hardest to treat) are now using a scorpion poison which illuminates cancer cells in UV light, therefore allowing them to operate with reduced risk of cutting away brain tissue.
I know it gets thrown around a lot, but cancer is no longer a death sentence, and hopefully soon we can all be free from cancer.
Special props to all the scientists in that field btw, simply amazing work.
