What is Cancer?


Cancer is a disease resulting from uncontrolled growth and spread of abnormal cells in the body, interfering with normal organ function. The term cancer does not refer to a single disease, but rather encompasses a large number of different cancers, with different behaviours, that are not all treated in the same manner.

Cancer can develop in any organ of the body, but the most common organs involved are the breast, cervix, colon, lungs and prostate. Unless treated, cancer may lead to death. The causes of cancer are many, but all have in common that damage to cells leads to abnormal cell growth and proliferation. Common examples of agents that may cause cancer include smoking, excessive alcohol consumption, excessive sun exposure, poor diet and lack of exercise, diesel fumes, and certain infections. .
