Causesof the cancer
Cancer is a group of diseases that affect human cells. Cancer can occur almost anywhere in the body. Cells in nearly any organ can become cancerous.
The cause of cancer is not fully understood, but there are several known risk factors. The most common risk factors are tobacco use, diet, obesity, and sun exposure. Other risk factors include exposure to radiation, certain chemicals, and viruses.
Tobacco use is the leading cause of cancer in the world. Tobacco smoke contains more than 7,000 chemicals, including more than 70 known to cause cancer. Cigarette smoking is the most common cause of cancer in the world.
Diet is also a major factor in the development of cancer. A high-calorie diet that is high in fat and low in fruits and vegetables is associated with an increased risk of cancer. Obesity is also a major risk factor for cancer.
Sun exposure is a major risk factor for skin cancer. Sun exposure also increases the risk of other types of cancer, including cancer of the eye, brain, and other parts of the body.
Radiation exposure is a known risk factor for cancer. X-rays and other types of radiation can increase the risk of cancer.
Chemicals in the environment can also increase the risk of cancer. Some chemicals, such as asbestos, are known to cause cancer. Others, such as benzene, are suspected of causing cancer.
Viruses can also cause cancer. Some viruses, such as the human papillomavirus (HPV), are known to cause cancer.
Prevention of Cancer
There is no sure way to prevent cancer, but there are some things you can do to reduce your risk.
