What causes cancer?

What causes cancer?

Several factors contribute to the development of cancer in your body. Smoking and using tobacco products is one of the main causes of:

• Lung cancer.
• Oral cancer.
• Laryngeal cancer.
• Esophageal cancer.

Other causes of cancer include:

• An unhealthy lifestyle. Eating high-fat or high-sugar foods can increase your risk for many types of cancer. You’re also more vulnerable to disease if you don’t get enough exercise.
• A toxic environment. Exposure to toxins in your environment, such as asbestos, pesticides and radon, can eventually lead to cancer.
• Radiation exposure. Ultraviolet radiation from the sun significantly increases your risk for skin cancer. Over-exposure to radiation treatment can also be a risk factor.
• Hormone therapy. Women who are taking hormone replacement therapy may have an increased risk for breast cancer and endometrial cancer.
