Abstract

One cell at a time goes through a change to develop cancer. This transition may be brought on by inherited elements as well as exogenous stressors. Cancer was the leading cause of mortality worldwide in 2008 with 7.6 million deaths, or about 13% of all deaths. Lung, stomach, liver, colon, and breast cancer are the most common cancers that result in mortality each year. In this study, the onset of cancer, its types, prevention, and risk factors are all discussed in detail. Different symptoms will manifest based on the type of cell or organ that the cancer has affected. Since stomach cancer rarely shows warning signs in the early stages, one skin eruption that has been seen on the face has been related to the disease.
