Cancer staging is a system developed by doctors to classify the advancement of cancerous diseases for diagnostic purposes. The stages (I, II, III and IV) are based on the extent that cancer has spread (metastasized) beyond its original location. This system is used to communicate the most accurate diagnosis and treatment plans.
Many factors can cause the development of cancer in the body. Some of these factors such as heredity (a disease that runs in the family) cannot be avoided. Others, such as lifestyle, can be controlled.
For instance, the use of tobacco is one of the main causes of cancer, especially lung cancer. Tobacco use, whether in the form of smoking, chewing or exposure to second-hand smoke (smoking by others), can also cause cancer of the mouth and larynx, esophagus, throat and many other parts of the body.

Other primary causes of cancer include:
- Diet/nutrition: A poor diet might increase your risk of cancer. For instance, eating large amounts of high-fat foods can contribute to cancer of the colon and prostate. Excess weight can also be a contributing factor for various types of cancer including breast, uterus, ovary, prostate and colon. A proper diet and exercise is key to minimize your risk.
- Environment: Cancer can develop if the person is exposed over a period of time to various chemicals in the environment including pesticides, asbestos and radon.
- Exposure to radiation: Too much exposure to the sun (ultraviolet radiation) can cause skin cancer. In addition, over-exposure to x-rays or to radiation therapy (as part of cancer treatment) might be a risk factor for cancer.
- Hormone therapy: Women who are going through menopause might receive a prescription for hormone replacement therapy, either estrogen alone or in combination with progesterone. The use of both of these hormones together has been shown to increase the risk of breast cancer. A woman who still has her uterus and is taking estrogen alone (without progesterone) has a greater risk of endometrial cancer.
