It is difficult to study the environmental causes of cancer, says colorectal oncologist and SurvivorNet medical advisor Dr. Heather Yeo. And the scientific community is very stern in its rebuke of claims about “such and such a chemical causing cancer” when there is no data to back them up. There is also a lot of fear created in this way. But that hasn’t stopped many people from asking the questions about toxins and carcinogens in air, water, and household products. The National Cancer Institute estimates that anywhere from 4 percent to 19 percent of cancers are due to environmental exposures. Fran Drescher’s non-profit, Cancer Schmancer, believes that figure is much higher and educates women about how to reduce their exposures to toxins and live a healthy and balanced life.
