Advanced breast cancer edges up in younger women

In this Monday, Feb. 25, 2013 photo, Dr. Rebecca Johnson, a cancer specialist at Seattle Children's Hospital, poses in an exam room at the hospital in Seattle. Johnson is the lead author of a new study that shows that advanced breast cancer cases have increased slightly among young women, a 34-year analysis suggests, raising many questions about possible reasons even as the disease remains uncommon in women younger than 40. Johnson herself was diagnosed with early-stage breast cancer at age 27, 17 years ago. Unlike women in the study, Johnson’s cancer was caught early.
