Adds Formaldehyde

1 US Updates List of Known Human Carcinogens

Formaldehyde, used in composite wood products, plastics, as a lab preservative and in some hair straightening products has been added to the US government’s Report on Carcinogens. It’s been listed as “known to be a human carcinogen,” says an announcement. Styrene, the chemical used in the manufacture of styrofoam, has been listed as “reasonably anticipated” to cause cancer. Cautions the announcement, “A listing in the Report on Carcinogens does not by itself mean that a substance will cause cancer. Many factors, including the amount and duration of exposure, and an individual's susceptibility to a substance, affect whether a person will develop cancer." The risk, say experts, largely comes from the substances’ uses in industry. There are now 240 substances on the list.

Overall Reduction in Risk

2 Prostate Enlargement Drugs Up Cancer Risk

Two large studies looking at the link between a class of drugs known as 5-alpha reductase inhibitors that treat enlarged prostates and the small increase in the development of aggressive prostate cancer have the FDA calling for manufacturers to add the risk to the warning label. The studies examined the drugs Proscar (finasteride), Avodart and Jalyn. Propecia, low dose Proscar, treats hair loss in men and was not part of either study but will have the risk added to its label as well. Studies show a 24 percent risk in the chance of developing low-grade cancer and a one percent increase in high-grade disease. While many experts agree that these drugs reduce the risk overall, Dr. Anthony D’Amico said, "I think that the warning is appropriate. The risk is very small, but not zero."
