Since Cynthia Nixon just talked about her breast cancer (I believe detected by a mammogram in her very early 40s) as well as Cheryl Crow and Melissa Etheridge also in their early 40s. Kylie Minogue was in her mid 30s. And of course, there are the thousands of young women out there we haven't heard of. Routine mammograms are advised to women starting in their 40s. I know breast tissue is denser when we are younger so cancer is less detectable but it seems breast cancer is being seen in younger and younger women. I'm wondering if this advice should be changed and directed at women starting in their 30s?
