Probably all of us have random rogue cancer cells floating around in our bodies but by and large, in the majority of cases, our immune system circulates and acts as a surveillance mechanism and kills off those few tumor cells.

HIV/AIDS from converted from a lethal disease into a chronic disease because basic scientists' fundamental research was done that illuminated aspects of that virus and allowed the generation of therapies like antiretroviral therapies. And so now HIV/AIDS is not a lethal disease, it is a chronic disease.

I think there's a lack of understanding which is partly our fault as scientists and physicians in not communicating well enough with the public. But there's a lack of understanding of how important biomedical research is.

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

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.

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

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.

I think that the marriage of academic medical centers and academicians with the private sector is a very, is a marriage made in heaven because it's the best way to get basic discoveries from the laboratory into new therapeutics for our patients.

The biggest risk factor for cancer is aging.

Hepatitis C was a devastating disease but because fundamental research was done in hepatitis C, it is now curable. It is now absolutely curable with new medications. So this is transformative.

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.

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.

Cancer can no longer be classified according to the organ in which it arises. It has to be characterized in terms of the genetic mutation that exists.
