The biggest risk factor for cancer is aging.

I like to think of making cancer a chronic disease rather than focus just on curing cancer.

The decrease in incidents of death from cancer is largely attributable to new medicines or therapeutics. Perhaps a third is attributable to changing our environment, and that includes of course smoking which I believe accounted for probably 20 percent of deaths from, certainly from lung cancer, more than that from lung cancer, but from cancer overall.

If you have a pap smear every year, there's no reason to develop cervical cancer.

When you think of the costs of cancer care, one can imagine that drugs like checkpoint blockers or transfer of these T lymphocytes are actually cost-saving, just as treatments for hepatitis C, while expensive, overall save money by preventing hepatitis and hep - hepatocarcinoma in patients.

Precision medicine is one way to attack cancer and it's proven to be very effective but, remember that like HIV/AIDS, you're going to need combination therapies.

There are clearly environmental factors that can decrease the incidence and death from cancer. I would still say though that the majority of cancers cannot be prevented at this point, but they can be treated and they can be treated two major ways.
