Is It Possible to Prevent Cancer?

Read Transcript

The most exciting thing for me as a scientist who studies outcomes, who studies the epidemiology of cancer is the realization that if we simply apply the things that we already know today, the number of lives that could be saved. We know for example about 100, 000 Americans die not just from cancer but from all things every year because of lack of access to cure, primarily due to the lack of insurance, that's number one.

In the the area of cancer, we actually have good data that suggest that if we simply applied all the things that we know today instead of 500, 000 dying of cancer this year if we had started applying what we know today just 20 years ago, at least 200, 000 of that 500, 000 that died to, they are dying this year would not have died.

So the most exciting thing about me and what really motivates me trying to get people to apply what we know today the things that I know are not being applied. Good diet, physical activity, trying to maintain as close to a normal body weight as possible. In the area vaccines, hepatitis B and HPV vaccine and HPV vaccine actually does prevent some cancers.

We actually believe that HPV vaccine should be given to boys because it prevents head and neck cancer in boys and girls and some genital cancers in both boys and girls when they are adults in their are 50s. There are some cautions that we need to take in terms of environmental pollutants, there are some cautions we need to take in terms of drugs and medications.

And of course sun avoidance which can actually prevent a lot of skin cancers both, the squamous cell cancers that are more of an annoyance as well as some of the more melanomas that can actually kill.
