In Wednesday's medical report, CBS News Health Correspondent Dr. Emily Senay reviews studies on breast cancer and smoking among college students.
Meat cooked very well-done can lead to a higher risk of breast cancer for women, researchers report. A study has found that women who prefer hamburger patties, steaks, or bacon cooked well done have a five times higher risk of breast cancer than those who like their meat cooked medium or rare.
Carcinogens formed during cooking may be to blame, doctors say. Others say more research needs to be done before that is proven to be the cause.
The flip side of the problem is undercooking meat, which has been associated with the deadly E. coli bacteria. To avoid this, meat should be cooked all the way through, Dr. Senay says.
In other medical news, a recent study found that more college students are smoking cigarettes. Researchers found that over the last four years, the number of college students smoking has gone up 28 percent, regardless of sex, age, race, or year in school.
The study, published in the Journal of the American Medical Association, this week, says that high school students are actually ahead of college kids when it comes to lighting up. Researchers say that 37 percent of high school seniors currently smoke.
