Cancer that forms in tissues of the kidneys. Kidney cancer includes renal cell carcinoma.e., cancer that forms in the lining of very small tubes in the kidney that filter the blood and remove waste products and renal pelvis carcinoma which is cancer that forms in the center of the kidney where urine collects. It also includes Wilms tumor, which is a type of kidney cancer that usually develops in children under the age of 5.
Almost 85% of this tumor are renal cell carcinomas. A less common type of kidney is Papillary carcinoma. Other rare kidney cancers include: Renal sarcoma, Collecting Duct carcinoma, Medullary and Chromophobe carcinomas.
kidney cancer develops most often in people over 40, but no one knows the exact causes of this disease. Research has shown that people with certain risk factors are more likely than others to develop kidney cancer. The risk factors for kidney cancer are smoking,obesity, high blood pressure,long term dialysis, Some people have a higher risk of getting kidney cancer because they come in contact with certain chemicals or substances in their workplace. Coke oven workers in the iron and steel industry are at risk. Males are more likely than females to be diagnosed with kidney cancer. Most people who have these risk factors do not get kidney cancer. On the other hand, most people who do get the disease have no known risk factors. People who think they may be at risk should discuss this concern with their doctor. The doctor may be able to suggest ways to reduce the risk and can plan an appropriate schedule for checkups.
Kidney cancer symptoms are often overlooked because tumours are usually slow growing and not suspected until the patient begins to experience symptoms such as blood in the Chronic fatigue, rapid weightloss,Leg and ankle swelling,high blood pressure,Fever,Presence of blood in urine,Pain in side or are lower back,Mass or lump in the abdomen. a palpable mass. Since back pain is common among people over 40 years of age, such pain is often ignored and the presence of kidney cancer can go undetected. Kidney cancer may also cause high blood pressure.There are many variations of kidney cancer. The most commonly diagnosed type of kidney cancer is renal cell carcinoma. It accounts for more than 85% of kidney cancer diagnosis'.Keep in mind that these symptoms are also the signs for many other illnesses.
Urine is checked for blood and other signs of disease. The lab checks the blood to see how well the kidneys are working.Cancer of the kidney is most commonly detected with either computed tomography (CT) scan, ultrasound or magnetic resonance imaging . Kidney cancer cells may also break away from the original tumor and spread to other parts of the body such as the lymph nodes, bones or lungs, with about one third of cases showing metastasis at the time of diagnosis.
To plan the best treatment, the doctor needs to know the stage of the disease. The stage is based on the size of the tumor, whether the cancer has spread and, if so, to what parts of the body.Staging may involve imaging tests such as an ultrasound or a CT scan,MRI. For this test, a powerful magnet linked to a computer makes detailed pictures of organs and blood vessels.In early stage of kidney cancer, but the tumor measures more than 2 3/4 inches. The cancer cells are found only in the kidney.In the next staget he tumor does not extend beyond the kidney, but cancer cells have spread through the lymphatic system to one nearby lymph node; or The tumor has invaded the adrenal gland or the layers of fat and fibrous tissue that surround the kidney, but cancer cells have not spread beyond the fibrous tissue. Cancer cells may be found in one nearby lymph node; or The cancer cells have spread from the kidney to a nearby large blood vessel. Cancer cells may be found in one nearby lymph node.In the next stage the tumor extends beyond the fibrous tissue that surrounds the kidney; or Cancer cells are found in more than one nearby lymph node; or The cancer has spread to other places in the body such as the lungs. Recurrent cancer is cancer that has come back after treatment. It may come back in the kidney or in another part of the body.
