Does tetrachloroethylene causes cancer?

The chemical tetrachloroethylene or PCE is carcinogenic. This potentially life-threatening effect was discovered after a study found that people who had lived near a dry cleaning facility while they were growing up had double the odds of developing cancer. Now, many are trying to determine if PCE can cause cancer in humans as well. The answer is yes and no, depending on where you live and what you do with the chemical.
