Cancer of the Kidney
There are several varieties of kidney (renal) cancer, including: renal cell carcinoma, which forms in the lining of a renal tubule (25,000 cases each year in U.S., leading to 11,000 deaths); transitional cell cancer, which occurs in 10 percent of all kidney cancers and typically affects middle-age women; and Wilm's Tumor, which accounts for 95 percent of renal cancers in children under age 14. Almost all solid kidney tumors are cancerous; they often metastasize (spread) to other organs, especially the lungs. Kidney cancer affects men one and a half times more often than women and represents 2 percent of all cancers in adults.

Adenocarcinoma of the Pancreas
The pancreas is a small gland next to the stomach and small intestine and is responsible for producing digestive enzymes and two important hormones, insulin and glucagon. Adenocarcinoma of the pancreas is a malignant tumor that forms in the cells of the pancreatic duct, from where it can spread to the liver or lungs. Adenocarcinoma of the pancreas is seen nearly twice as often in men than in women and two to three times more often in smokers than in non-smokers.

Cancer of the Bladder
The bladder is the human organ that collects and discharges urine (liquid waste) from the body. High concentrations of specific chemicals in the urine caused by environmental factors will result in bladder cancer; smoking is a very strong risk factor. More than 50,000 new bladder cancer cases are diagnosed each year, leading to 10,000 deaths. Men are four times more likely than women to be affected by the disease; bladder cancer rarely occurs in people under age 40.

Colorectal Cancer
The colon is one of the segments of the large intestine, which absorbs water and electrolytes from the feces (solid waste). In western countries, colorectal cancer (malignant tumors in the colon or rectum, the last sixteen inches of the colon) is the second most common type of cancer and the second leading cause of cancer death. Colon cancer is more characteristic in women, while rectal cancer is more common in men. The chance that one will develop these colorectal cancers increases after age 40. Colorectal cancer can metastasize to the liver and lymph nodes and even the lungs. If colorectal cancer does not metastasize, the survival rate is 90 percent; but only 30 percent survive if it spreads to the nearby lymph nodes.
