I would ask his oncologist..
The reality in this case is very different from what you perceive it to be.
How old is your dad? Is the cancer localized or has it spread? What's his health like? Are there any symptoms? Was he sick often in his life? All these things play a role, but most important one right now is: has it spread elsewhere?
The cells in our body mutate often, but our immune system beats them every time. It's when it doesn't manage to beat them that they can become cancerous, and from then on they seem friendly to our immune system.
Cancerous cells are weaker then healthy cells. The basic principle on which many chemotherapeutic agents work is that if we flood the whole body with a cell-destroying poison, the first ones that are going to die are the weakest ones. Of course, many healthy ones will die too (hence the loss of hair and all the other complications), but the healthy ones may regenerate...
If the cancer hasn't spread, most common choice is to surgically remove it, and then hope the immune system will do it's job in life aferwards.
It would be very wise at this point to spend time reading everything there is about his condition, and understand it thoroughly, so that you know exactly where each choice you make could take you.
