Routine mammography screening has potential downsides, including false negatives, radiation exposure, overdiagnosis, and increased mortality in younger women. Patients need full information for informed decisions about breast cancer screening.

Area of Science:

  • Radiology
  • Oncology
  • Public Health

Background:

  • Routine screening mammography is widely accepted by the American public.
  • Understanding the potential risks associated with mammography is crucial for informed patient decision-making.

Purpose of the Study:

  • To identify and discuss less recognized risks of mammography screening.
  • To inform patients about the downsides of mammography for better decision-making.

Main Methods:

  • Review of literature on mammography screening risks.
  • Analysis of adverse outcomes including false negatives, radiation hazard, and overdiagnosis.
  • Examination of societal and individual costs associated with screening.

Main Results:

  • Mammography screening carries risks such as false negatives leading to false reassurance.
  • Significant downsides include radiation exposure, overdiagnosis of breast cancer, and a paradoxical increase in mortality in women aged 40-49.
  • Women are often poorly informed about these potential harms.

Conclusions:

  • Despite widespread belief in benefits, mammography screening has significant, often under-recognized, downsides.
  • There is a need for improved patient education regarding mammography risks.
  • Continued research into new methods for reducing breast cancer mortality is essential.
