A new study is causing many women to question how often they receive a mammogram.
Currently, the U.S. Preventative Services Task Force recommends that women between 50 to 74-years-old receive a mammogram.
However, a new study suggests that those tests should be performed much earlier.
Researchers at Harvard Medical School studied more than 600 women who died from breast cancer.
They found half of the women were under the age of 50.
Experts say it appears breast cancer that is found in younger women is more aggressive, while the disease is less severe in women over age 70.
They also found only a third of those who died had received a mammogram.
Two-thirds had not.
Not everyone is on board with changing the standards.
Some experts say regular mammograms in young women could lead to over-diagnosis, meaning the scans will find things that are not cancer and cause unnecessary fear, anxiety and procedures that could have been avoided.
