Cancer is a disease in which some of the body's cells grow uncontrollably and spread to other parts of the body.
Cancer can start almost anywhere in the human body, which is made up of trillions of cells.
The main reasons people get cancer are genetics and certain environmental or behavioral triggers.
The tendency to develop some types of cancer is believed to be inherited — that is, the genes you were born with might carry a predisposition for cancer.
Some symptoms of cancer include.
Fatigue or extreme tiredness that doesn't get better with rest.
Weight loss or gain of 10 pounds or more for no known reason.
Eating problems such as not feeling hungry, trouble swallowing, belly pain, or nausea and vomiting.
Swelling or lumps anywhere in the body.
Researchers know that there are several viruses that can lead to cancer.
For example, the human papillomavirus (HPV) can cause cervical and several other cancers.
And hepatitis C can lead to liver cancer and non-Hodgkin's lymphoma.
The cancer mortality rate is higher among men than women (189.5 per 100,000 men and 135.7 per 100,000 women).
When comparing groups based on race/ethnicity and sex, cancer mortality is highest in African American men (227.3 per 100,000) and lowest in Asian/Pacific Islander women (85.6 per 100,000).
