Study Shows that Alcohol Increases Risk of Cancer

A recent study has show that alcohol can increase the chances of getting breast cancer in women. Studies have shown a link between drinking alcohol and breast cancer but they have yet to determine if certain types of alcohol is more dangerous than others.

The study analyzed the drinking habits of 70,033 women and asked them various questions during health exams between the years 1978 and 1985. By the year 2004, 2,829 of those women had been diagnosed with breast cancer. The study found that women who had one or two drinks a day increased their risk by 10 percent and women who had more than three drinks a day increased their risk by 30 percent.

Experts think that alcohol raises hormone levels in the blood to levels that could cause cancer. Doctors say that other factors, such as genetics, obesity, and age are more important factors that can raise the risk of breast cancer.
