The document discusses cancer screening and some of its potential harms and benefits. It notes that screening can potentially avoid 3-35% of premature cancer deaths depending on assumptions, but also has several potential downsides. These include false positives that cause unnecessary anxiety and procedures, overdiagnosis of conditions that would not have become clinically significant, and false negatives that delay diagnosis and treatment. The document also provides information about breast cancer screening methods like clinical breast exams and mammograms, as well as cervical cancer screening via Pap tests.
2. Introduction to Screening
Estimates of the premature deaths that
could have been avoided through
screening vary from 3% to 35%, depending
on a variety of assumptions. There
are, however, several potential harms that
must be considered against any potential
benefit of screening for cancer.

3. Con” Introduction to Screening
Another harm is the false-positive
test result, which may lead to anxiety
and unnecessary invasive diagnostic
procedures.
gehad abdullah
4. Cont” Introduction to Screening
A less familiar harm is over
diagnosis, i.e., the diagnosis of a condition
that would not have become clinically
significant had it not been detected by
screening. This harm is becoming more
common as screening tests become more
sensitive at detecting tiny tumors.
Finally, a false-negative screening test
may falsely reassure an individual with
subsequent clinical signs or symptoms of
cancer and thereby actually delay
diagnosis and effective treatment.
