Dr. Smith has two patients, one of whom has elevated blood PSA. A
digital exam reveals that both patient 1 and patient 2 have enlarged
prostate glands. Patient 1’s enlarged prostate has the same shape as
a smaller prostate, except that it is larger than normal, with a smooth
contour. Patient 2’s prostate is enlarged and asymmetrical, with a
rough contour. In what way are these patients’ lives probably being
affected by their enlarged prostates? Explain how the doctor was able
to conclude that one of the patients is likely to have prostate cancer.
