Why is cancer so hard to cure?

Cancer research seems to get a ton of fundraising and support, but there is still no cure. And, how does one actually cure cancer? What would we need to discover?

1. There are many different kinds of cancer.
2. There are many different causes of cancer.
3. Current treatments require killing the cancer cells. You can't "fix" a tumor.
4. Cancer is mutated human cells. Your body doesn't know they're harmful.
5. The cancer cells don't commit suicide like normal cells.
6. It grows uncontrollably.
7. It can break apart and grow more cancer elsewhere.
8. It can grow inside organs, causing them to malfunction.

Think of the human body like a beautiful garden. There's a few weeds growing in the middle, though.(cancer cells) Your actions:

A. Prevent more weed seeds from getting into the garden (Reducing cancer causes)

B. Mulch the ground (Increase resistance to cell mutations)

C. Prevent the weeds from spreading.

D. Remove the weeds. (Cut out cancer cells)



Saying "we have no cure" isn't exactly right. We have a cure for many of them, and prevention for others.
