Breast cancer doesn't care if you don't get a mammogram because you are under 50

The number of women in their 40s undergoing mammograms has declined after the U.S. Preventive Services Task Force recommended that women delay regular breast cancer screenings until age 50, over their previous recommendation of age 40. Fools.With something like 1 in 8 women getting breast cancer women are crazy to not get mammograms/MRIs no matter their age. As I have recently discovered, breast cancer doesn't discriminate against the young.

My 41 year old wife has been getting mammograms annually for several years due to a family history. Sure enough, this year, a lump was found that was cancerous. She had a lumpectomy and is now preparing for chemo (Stage I tumor was very aggressive, 8 of 9 on Bloom-Richardson scale). And my wife was lucky. A 40 year old woman in my wife's office, who didn't have a family history of cancer, went for her first mammogram last month. Not only was breast cancer found, but it had spread into the chest. Hopefully it has been caught in time.

Now imagine if either of them hadn't had their mammograms at 40/41. While my wife would have had one due to family history anyway, her co-worker would not have had one under the revised standards. Then what?
