Chapter 22, Problem 5RQ
Summary Introduction
To determine: The seven warning signs of cancer.
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 clinical manifestations of cancer are numerous and depend on the variety and intensity of symptoms.
The word tumor is used to refer to swelling, but now it is used to describe the new growth or neoplasm (cancerous growth).
