Cancer Is Man Made "Cancers are primarily an environmental disease with 90-95% of cases due to lifestyle and environmental factors and 5-10% due to genetics. Common environmental factors leading to cancer death include: tobacco (25-30%), diet and obesity (30-35%), infections (15-20%), radiation, stress, lack of physical activity, environmental pollutants. These environmental factors cause abnormalities in the genetic material of cells." http://en.wikipedia.org/wiki/Cancer Cancer was virtually unknown 150 years ago before coal and oil. Today, you are statistically likely to get one form of cancer or another within your industrialized lifetime. I had thyroid cancer when I was 37- they removed my thyroid and I now take pills for the rest of my life to replace the effects my thyroid served in my body before it went cancerous. You are destined to encounter cancer directly or indirectly in your life. I grew up in The Bronx, which is cleaner than any other borough but still full of stale, used air and contaminants everywhere. I say this because I now live with my son in the country with fresh mountain air and fresh streams and forests full of ferns and trees far removed from Bronx air. I am pretty sure my son won't get cancer in his lifetime. If nothing else, all his cousins, aunts and uncles here in the mountains- all cancer free- are a testament. I point this out because I wonder how many country women get breast cancer- you know- the cancer that gets the most attention- versus how many city women get it. But overall, I am amazed that science has come to the clinical realization that cancer is man made. What are your thoughts on cancer?
