The number of young women diagnosed with advanced stage breast cancer has increased.
Researchers from Seattle Children’s Hospital studied large databases to learn more about the trends in breast cancer diagnosis.
The group studied women from 1973 to 2009.
They found there has been a steady increase in the number of 25 to 39-year-old women diagnosed with advanced stages of the disease.
Officials say they saw about a 2 percent increase each year.
Doctors say these women tend to have a worse prognosis because they are not routinely screened for the disease and are less likely to have health insurance.
