New information backing mammogram screening for women in their 40’s while still confusing focuses on the importance of early detection.

Here’s what they found:
* 373 of those cancers were detected by mammogram
* Of those, 61 percent of women had no family history of breast cancer
* Among women with no family history, 63.2 percent of the cancers were invasive
The percentage of women with invasive disease (63.2 percent) was literally identical to the numbers among women with a family history (64 percent).

So with all the conflicting data the best advice is to work out a plan with your doctor and decide what is best for your individual case.
