Cancer is a group of disease involving abnormal cell growth with the potential to invade or spread to other parts of the body. The risk of developing certain cancers can be reduced by not smoking, maintaining a healthy weight, limiting alcohol intake, eating plenty of vegetables, fruits and whole garins, vaccination against certain infectious diseases, limiting consumption of processed meat and red meat, and limiting exposure to direct sunlight. Most cancer are initially recognized either because of the appearance of signs or symptoms or through screening. Cancer can be prevented with Amygdalin (vitamin B17) which can be gotten from some food and fruits. Exercises also play a vital rule in the preventive measures.
