The Complexity of Cancer Screening
Cancer screening is a complicated and tricky practice in medicine. The challenge lies in determining the behavior and risks associated with different types of lesions found. Some cancer lesions are aggressive and threatening, while others may never cause harm. The goal of screening is to strike a balance by detecting cancers that are likely to be harmful and treating them appropriately, while avoiding the overdiagnosis and unnecessary treatment of cancers that would not pose a threat.
