When we think about lung cancer, the biggest environmental factor is without doubt smoking. Um, that would make a huge impact and has made a huge impact on the incidence of lung cancer. We have to keep pushing that and making it clear to everybody why smoking is so dangerous.

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.

The four most common cancers that account for about 80 percent of all cancer deaths are lung, breast, colorectal cancer, and prostate cancer.

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

Cancer vaccines are in the future. And they could be very effective. Checkpoint blockade, which is acting your immune system to recognize those cancer cells and kill them is another very promising approach and there have been some checkpoint blockade drugs out in the market now that will release the brake on T lymphocytes, the T lymphocyte is your major killer of tumor cells.

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.
