Cancer and prevention

More than 1,359,000 new cases of cancer will be diagnosed in the United States this year alone and approximately 550,000 patients will die this year from cancer. In spite of the near 25 billion dollars spent on cancer research in the past twenty years, cancer deaths have actually increased over that same time period. This has raised major concern among researchers and clinicians alike-it's time to rethink our approach to cancer prevention and treatment. If there has been any improvement in cancer risk, it seems to be with the ability to detect some cancers sooner, i.e. mammography for the detection of breast cancer and PSA tests for prostate cancer.

It seems that everything we do or eat these days allegedly causes cancer. Excessive exposure to sunlight increases the risk of skin cancer. Asbestos workers have an increased risk of developing an unusual form of lung cancer called a mesothelioma. Smoking and secondary smoke are the main reason that lung cancer is the leading cause of cancer deaths (over 158,000 deaths in 1996 alone). Radiation, charcoal grilled steaks, too much fat in our diet, saccharin, and numerous chemicals increase our risk of cancer. These are referred to in the medical literature and media as carcinogens (those things that increase our risk of developing cancer).

Since the first report that chimney sweeps had an increased risk of scrotal cancer because of their exposure to soot, we have become more and more afraid of our environment. Our bodies are being exposed to far more chemicals than any previous generation. The Environmental Protection Agency has estimated that there are well over 60,000 chemicals in commercial use today and they are increasing at a rate of 1,000 per year. What is the one common denominator? They all increase oxidative stress. Oxidative stress is the key to understanding new strategies for preventing and fighting cancer. To learn more, click here
