Tobacco, UV rays, viruses, heredity, and age are the main causes of cancer. — © Harold E. Varmus
Tobacco, UV rays, viruses, heredity, and age are the main causes of cancer.
I shall borrow two words used for a slightly different purpose by the great demographer Alfred Lotka to distinguish between the two systems of heredity enjoyed by man: endosomatic or internal heredity for the ordinary or genetical heredity we have in common with animals; and exosomatic or external heredity for the non-genetic heredity that is peculiarly our own - the heredity that is mediated through tradition, by which I mean the transfer of information through non-genetic channels from one generation to the next.
You would think that UV just causes mutations, but it doesn't, you need a gene to be active for it.
You would think that UV just causes mutations, but it doesn't; you need a gene to be active for it.
A lot of people are listening and most people believe global warming is a problem and they'd like to see it addressed. But governments and the biggest companies in the world don't want to deal with it like they didn't want to deal with the fact that tobacco causes cancer.
It's so important to protect your eyes from harmful UV rays - you use SPF every morning, but you need to protect your eyes, too.
Some scientists claim - although these claims are contentious - that they can form deadly isomers with simple X-rays and that hafnium can multiply the power of these X-rays to an astounding degree, converting them into gamma rays up to 250 times more potent than the X-rays.
Fluoride causes more human cancer, and causes it faster, than any other chemical.
UV is bad for molecules because its high energy breaks the bonds between a molecule's constituent atoms. That's why UV is bad for you, too: it's always best to avoid things that decompose the molecules of your flesh.
I myself smoke, but my wife asked me to speak today on the harmfulness of tobacco, so what can I do? If it's tobacco, then let it be tobacco.
I'm glad now, at age 66, that I never used alcohol or tobacco... I've buried a lot of friends who used tobacco or alcohol.
Unlike other diseases, the vulnerability to cancer lies in ourselves. We always thought of disease as exogenous, but research into cancer has turned that idea on its head - as long as we live, grow, age, there will be cancer.
I use sunscreen every single day, even if I'm not going outside in the sun, because I'm near a window. I can always get those UV rays on my face, so I always apply sunscreen on my face and neck. It's like brushing my teeth: I feel weird if I don't apply sunscreen.
We live in a dancing matrix of viruses; they dart, rather like bees, from organism to organism, from plant to insect to mammal to me and back again, and into the sea, tugging along pieces of this genome, strings of genes from that, transplanting grafts of DNA, passing around heredity as though at a great party.
Surveying the way viruses have been discovered in the past, I came to the conclusion that I could use my technology that I developed as a graduate student - DNA microarray technology - to create a chip that would simultaneously screen for all viruses ever discovered, and furthermore have the built-in capability of discovering new viruses.
In Europe, when tobacco was first introduced, it was immediately banned. In Turkey, if you got caught with tobacco, you had your nose slit. China and Russia imposed the death penalty for possession of tobacco.
My family has had a lot of trouble with cancer in particular. There are a lot of great causes out there but for me to pick one I would say anything that is cancer related.
