To begin, cancer is caused by uncontrolled division of abnormal cells. There a various types of cancer that can form in a person 's body. Renal, liver and digestive cancer would be discussed in this passage. Renal cancer also known as kidney cancer, occurs when the cancer cells form in the tubules of the kidney . Smoking, hypertension, and obesity are some of the high risk factors associated with renal cancers. Staging describes how the cancer has spread and according to America Cancer Society there are two types of renal cancer staging. There is the clinical stage, where the doctor best estimates the extent of the disease based on the results from the physical examinations, lab test and imaging. On the other hand the pathologic staging

Renal cancer can grow in the tissues around the tumor, the cancer can also move into the lymphatic system which has vessels through out the body. Lastly, renal cancer cells can enter the bloodstream and can be carried and deposited into other organs. Prognosis of renal cancer can determined by the survival rates of the disease. The five years survival rates determines the percentage of people who survived after five years of being diagnose with the disease however some people die of other diseases other than the cancer. According to the National Cancer Data base and based on patients diagnosed in the year 2001 and 2002, the survival rates include; stage 1- 81%, stage 2- 74%, stage 3- 53% and stage 4- 8% (American Cancer Society, …show more content…
Among the various types of digestive tumors, colorectal cancer is the most common malignancy, it is the second leading cause of death from cancers (Washington &Leaver, 705). Just like all other cancers, the digestive system cancers use the TNM staging system by the AJCC. This system maybe used clinically before or after surgery. Depending on the location of the tumor in the digestive system, TNM staging will still include the primary site of the tumor, the number of lymph nodes involve and the extent in spread. Again, digestive system tumors can spread in different routes, for examples through the lymphatic chain or blood borne spread. For instance rectal cancer can spread to the liver by the venous drainage of the gastrointestinal system. It can also spread to lung when tumor embolus into the inferior vena cava (IVC) (Washington & Leaver, 711) . As a result of this, if a tumor to metastasizes in the digestive system it is going to be base on the lymphatic chain or the follow of blood. The prognosis of digestive system cancer depends on the location of the cancer and how early it was diagnosed and treated. Though colon cancer is the most common gastrointestinal malignancy, it has the best prognosis (Washington & Leaver, 705). Cancers of the esophagus and pancreas are usually diagnosed at an advanced stage
