Are Breast Cancers Detected by Mammography Different?

Vital Information:

  • A new study reports that while mammograms catch breast cancer in its early stages, it also finds cancer cells that grow slowly and may not need aggressive treatments. But when a tumor is found on the mammogram, doctors can't tell if it will spread quickly or not.
  • An observer notes that today's mammography techniques help catch most breast cancer tumors much earlier than was possible 20 years ago. But doctors aren't sure whether finding a tumor early in its development leads to more survival time for the patient, or if it just gets treatment started earlier in the development of the disease that runs its course.
  • Doctors are still trying to answer that question. The observer notes that learning to identify different breast cancer types and whether they grow quickly could help tailor treatment to the individual patient's needs.
