Cancer is a condition in which damaged body cells grow out of control. According to the World Health Organization's February 2017 fact sheet, cancer is one of the leading causes of mortality worldwide, accounting for 8.8 million deaths in 2015, or one out of every six deaths. In 2012, in Pakistan, over 63,415 males and 85,590 females were diagnosed with the disease. In addition to smoking, the following are cancer risk factors: Drinking a lot of alcohol, excessive body fat, a lack of physical activity, malnutrition. Types of cancer according to cause of death are lung cancer, colon and rectum cancer, liver cancer, stomach cancer and breast cancer which became cause of death of 1.80 million deaths, 935000 deaths, 830000 deaths, 769000 deaths, and 685000 deaths respectively. Chemotherapy uses drugs that target quickly dividing cells to kill malignant cells. When a person is diagnosed with cancer, the prognosis is determined by whether the disease has spread, as well as the type, severity, and location of the cancer.
