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

If one has a routine colonoscopy at the age of 50 and then colonoscopies thereafter as the physician recommends, you could largely prevent colon cancer, you could detect it in its very earliest stages and cure it.

When I think of cancer prevention, I think of cancer vaccines, but I think more broadly of all that we can do to prevent cancer. And part of that is coming up with a vaccine that will work like the vaccines we have for hepatitis B or flu or polio.

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.

The key to HIV/AIDS was to say let's give a patient multiple different therapies at the same time and that makes the virus much less likely to mutate.

Once you close down your laboratory, you can't just rev it up again if you're able to finally get a grant.

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.
