Paraneoplastic syndromes are manifestations of cancer that often result from:
A) Radiation and chemotherapy
B) Compression of area vessels
C) Tumor-related tissue necrosis
D) Inappropriate hormone release
Ans: D
Feedback:
Paraneoplastic syndromes are manifestations in sites that are not directly affected by the disease; many are caused by excessive or inappropriate peptide hormone synthesis and release by cancer cells. Radiation and chemotherapy are cancer treatments that cause side effects unrelated to the paraneoplastic syndromes. Area vessel compression is a direct result of the tumor's location; area tissue necrosis is a direct result of area tissue destruction and death of healthy cells.
