Question
Chapter 22, Problem 2SQ
Summary Introduction
Introduction: Tumor is an abnormal tissue mass that may be solid or fluid-filled lumps. There are two categories of tumors namely benign and malignant tumors. Benign tumors do not invade other nearby parts and tissues in the body. Malignant tumors refer to cancerous tumors where abnormal cells divide rapidly and metastasize to new areas.
