Aisles in grocery stores and pharmacies are stacked with vitamins, minerals, herbs or other plants that you take in pill, capsule, tablet or liquid form. And, many of us buy these supplements and take them regularly, hoping to lower our chances of getting cancer and other diseases.
But do supplements really work wonders? Should you take them to help prevent cancer? Our experts say beware.
“Don’t be fooled by the label on the bottle,” says Sally Scroggs, health education manager at MD Anderson’s Cancer Prevention Center. “Researchers are still unsure about whether or not supplements actually prevent cancer.” Some studies have suggested that supplements may actually increase cancer risk by tilting the balance of nutrients in the body.

I’ve been writing about personal genomics for years. The standard concept of it is that you can order such genetic tests online, send your saliva or buccal swab to the lab where they analyze your DNA, then you can check online what kind of diseases you have elevated or lowered risk for. That’s how Navigenics, 23andMe or Pathway Genomics works. Now Pathway had a major announcement:
San Diego based startup Pathway Genomics announced [May 18th] that it will begin selling its DNA collection kits at Walgreens drugstores beginning in mid-May, for about $20 to $30. Unlike a pregnancy test, users won’t be able to get results immediately. They will have to send in their saliva sample and then go to Pathway’s website to select the particular test they want. Users choose from drug response ($79), which assesses how well an individual can metabolize certain drugs, predicting the best dosage for that person or whether they will be susceptible to certain side effects; pre-pregnancy planning ($179), which determines whether parents carry mutations for serious genetic diseases; health conditions ($179), which assesses risk for a number of conditions, including diabetes, Alzheimer’s, prostate cancer and more; or a combination of all three ($249). The kits won’t be sold in New York because the state’s laws require medical professionals to be involved in this type of testing.
As you may know, I’m not totally against direct-to-consumer genetic testing, but I really would like to see doctors and genetic counselors in this process. I think selling such kits through drugstores can only happen in the U.S. right now. Read more »
