Should women 30 and under with no family history of breast cancer be overly concerned about getting mammograms? Maybe not, according to a new study published in the Journal of the National Cancer Institute. Researchers from the University of North Carolina at Chapel Hill studied more than 117,000 women between the ages of 18 and 39 with no family history of breast cancer and found that cancer was rarely detected in those under 40. But, what about African-American women who are more likely to develop cancer under 45 than any other group--we're talking women being diagnosed in their 20's and 30's! We're confused... Here's what you had to say: P Moore commented: "I think it is never too early for women to get mammograms. I am a 36-year-old woman and I recently found a lump during one of my self-breast-exams."
