Are there downsides to mammography 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.
