"Experts recommend that women who are over 50 years old get a mammogram every one to two years. That's because small breast tumors can be seen on a mammograme before they can be felt by a woman or her health care professional."
First of all, their "experts" are people who just happen to make money off this test.
Secondly, the long term studies show that finding small tumors via mammography DOES NOT alter survivability, adds to your radioactive burden, and often results in unnecessary surgical procedures.
It's a good thing I am Well Informed.
