Chapter 22, Problem 1CT
Summary Introduction
To propose: Explanation of observations that higher rates of cancer are associated with increasing age.
Introduction: Cancer is caused due to abnormal cell growth. This occurs due to several genetic and epigenetic alterations that cause uncontrolled proliferation of cells. The word tumor is used to refer to swelling, but now it is commonly used to describe the new growth or neoplasm (cancerous growth). The clinical manifestations of cancer are numerous and depend on the variety and intensity of symptoms.
