Case for Cancer Concern

The list of carcinogenic risk factors grows yearly. From our own sun to the tiniest virus, it seems there’s no escaping cancer threat. While paranoia isn’t healthy, staying tuned to developing research is…

• CT scans: The National Cancer Institute claims the screenings — which are ordered by docs 3 times more today than in 1993 — could be exposing patients to unnecessary radiation, fueling concern that it leads to as many as 29,000 cases/year of cancer. Always inquire about other diagnostic tools and discuss whether the treatment plan would be dictated by CT results (if not, why get it?).

• Hepatitis viruses: The International Agency for Research on Cancer recently added to its Group I list of human carcinogens the hepatitis B and C viruses, which experts blame for the rise in liver cancer cases. Since both viruses are primarily transmitted through sexual contact or intravenous drug use, they are avoidable; if you’re considered high risk, there is a vaccine for hepatitis B.

• Bisphenol A: An endocrine–disrupting chemical that lines many metal and plastic containers, BPA is becoming increasingly scrutinized for possible cancer–causing effects. Fetuses and women of childbearing age are particularly vulnerable. Avoid plastics with recycling codes 3 and 7, and cut back on canned goods — go with cartons for soups, juices, and sauces. Transfer food from plastic to glass before microwaving.
