A) Increasing tissue blood flow
B) Providing essential nutrients
C) Liberating enzymes and toxins
D) Forming fibrous membranes
Ans: C

Malignant tumors affect area tissues by liberating enzymes and toxins that destroy tumor tissue and normal tissue.

The high metabolic rate of tumor growth causes the tumor to deprive the normal tissues of essential nutrients.
