Hello Dr. Markus,
I read your letter in the Phila Inquirer, Page B2, 10/04/2007 on Fluoridation.
A very interesting letter since I have worked for the Phila Water Dept for about 30 years,
however, I am an Administrative Supervisor, not a chemist or engineer, etc.
You state in your letter that
“There have been pockets of testicular cancer in adolescent males
in fluoridated areas.”
Can you cite any medical or scientific studies that have been published about this
or any other scientifically tested danger or risk of fluoride in the drinking water?
Thank you, in advance, for your response and your time.

Check out www.fluoridealert.org, or google testicular & fluoride
A 1992 New Jersey Department of Health report: “Between the years 1970 and 1989, the rate of osteosarcoma (among 10-19 year old males) was found to be 3.5 to 6.3 times greater in the fluoridated versus unfluoridated areas.”
