Answer to Question 1

Correct Answer: 1
The anorexiacachexia syndrome is specific to cancer because of the effect of cancer cells on the host's metabolism. The neoplastic cells divert nutrition to their own use while causing changes that reduce the patient's appetite. Early in the disease, glucose metabolism is altered, causing an increase in serum glucose levels. The tumor also secretes substances that decrease appetite by altering taste and smell and producing early satiety. Paraneoplastic syndromes are indirect effects of cancer. They may be early warning signs of cancer or indicate complications or return of a malignancy. An infection caused by cancer does not lead to anorexia. Esophageal obstruction is not a specific physiological effect of cancer.

Answer to Question 2

Correct Answer: 1
Simplified metabolic activities are a characteristic of malignant cells. The work of malignant cells is simpler than that of normal cells. Malignant cells loose specialization and differentiation. Malignant cells do not perform typical cellular functions. The transformation into a malignant cell is irreversible. Rarely does a malignant neoplasm revert to a benign state. Transplantability is another characteristic of malignant cells. Malignant cells often break away from the primary tissue site and travel to other locations in the body.
