Overview of CancerSummary
Cancer is a common health problem that causes an abnormal growth of cells. Cancer
can occur in almost any part of the body. The pathophysiology of cancer affects normal
cell growth and development. Cancer cells are abnormal, and they do not have a
specific function in the body. Common themes in the etiology of cancer include
exposure to carcinogens, genetic predisposition, and altered immunity. Cancer is a
process that occurs over time with several stages. Clinical manifestations of cancer are
often specific to the type of cancer. However, common symptoms of cancer include
increased fatigue, changes in weight or appetite, unusual bleeding or discharge, or a
lump in the breast or elsewhere. Understanding the etiology, pathophysiology, and
clinical manifestations are key elements in the provision of safe, effective nursing care
of the patient with cancer. - answer
