Question

All of the following are true regarding the pathogenesis of cancer EXCEPT:
the immune response may fail to identify and destroy cancerous cells
viral infections do not play a role in the development of any cancers
cellular dysplasia may occur in response to an adverse condition or exposure
loss of tumor-suppressor gene function may allow unrestrained cell growth

With regard to the natural history of prostate cancer:
O autopsy studies show that many men live with asymptomatic, undiagnosed prostate cancer
in cases of early, localized disease, prostate cancer is aggressive and has a very low 5-year
survival rate
O screening with PSA (prostate-specific antigen) is highly accurate (very sensitive and specific)
O all responses are correct

Expert Solution

Step 1

Introduction :-

PSA stands for Prostate-Specific Antigen, which is a protein produced by the prostate gland. PSA is commonly used as a marker for prostate cancer, as elevated levels of PSA in the blood can indicate the presence of prostate cancer or other conditions affecting the prostate.
