A 70-year-old patient
is found to have a high level of PSA in his blood (a tumor marker for prostate
cancer). For this reason, a physical and ultrasound examination is performed,
which reveals a mass growing in the peripheral part of the prostate. It is,
therefore, necessary to carry out a biopsy, which is performed in a fan-shaped
way by taking approx. 10 samples from both lobes. All samples are sent to
pathology and evaluated. Only in 2 captured samples are found changes
corresponding to carcinoma. What will the remaining 8 samples obtained, where a
healthy part of the prostate is present, look like?
