Kidney cancer is also called hypernephroma or renal cancer. Kidneys are fist-sized peritoneum organs on either side of the backbone.

Overview
Kidney cancer is also called hypernephroma or renal cancer. Kidneys are fist-sized peritoneum organs on either side of the backbone. The function of kidneys is to filter and clean your blood, take out waste products and make urine. Usually, kidney cancer originates in the lining of tiny tubes. Kidney cancer doesn't have any early symptoms. With the development of the cancer, frequent symptoms include blood in your urine, pain in your side, a lump in your abdomen and unexplained weight loss. Treatments include surgery, radiation therapy, chemotherapy or biologic therapy.
What are the symptoms of kidney cancer?
Early kidney cancer does not have any symptoms. As the tumor grows larger, people may notice one or more of the following symptoms:
- Hematuria (blood in the urine)
- Lower back pain on one side
- A mass or lump on one side of the lower back
- Fatigue and unexplained weight loss
- Edema of ankles and legs
Other health problems may also cause these symptoms. Only a doctor can tell for sure. A person with any of these symptoms should tell the doctor so that the problems can be diagnosed and treated as early as possible.
Who is at risk for kidney cancer?
Clinical data has suggested that the development of kidney cancer is related to several factors.
- Genetic and hereditary risk factors
- Hereditary papillary renal cell carcinoma
- Hereditary leiomyomatosis and renal cell carcinoma
- Lifestyle-related and job-related risk factors
- Smoking: Tobacco use increases the risk of developing renal cell carcinoma.
- Obesity: Clinical surveys demonstrate that kidney cancer has a close relationship with people who are very overweight.
- Workplace exposures: Clinical studies have suggested that workplace exposure to certain substances such as asbestos, cadmium, some herbicides, benzene, and organic solvents, particularly trichloroethylene, may increase the risk for kidney cancer.
- Drugs: Some studies have suggested that phenacetin (non-prescription pain reliever) and diuretics (medicines uesd to treat hypertension or heart failure by causing the kidneys to remove salt and fluid from the body) may be linked to kidney cancer.
- Advanced kidney disease: People with advanced kidney disease, especially those needing dialysis, have a higher risk of kidney cancer. The reasons may be the accumulation of the metabolic toxin.
- A family history of kidney cancer
- Gender: Men have about twice the risk of developing kidney cancer than women.
- Race: Epidemical data shows that African Americans have a slightly higher rate of kidney cancer than other races.
How to know you have kidney cancer?
- Lab Tests
- Urinalysis: This is the most common test for urinary system diseases. Red blood cells and white blood cells may be detected by the test.
- Blood chemistry tests: The levels of certain chemicals in the blood may be affected in patients with kidney cancer.
- Complete blood count: Anemia is very common in kidney cancer patients. Sometimes erythropoietin which is a kind of hormone, is made by the cancerous cells and can produce too many red blood cells.
- Ultrasonography: This is an painless test which uses sound waves to create a picture of the internal organs. Because tumors generate different echoes of sound waves than normal tissue, the doctor can locate a mass inside the body.
- Computed tomography (CT) scan and biopsy: CT scans are often used to diagnose kidney cancer. It can confirm the location of the cancer and show the organs near the kidneys, as well as lymph nodes and distant organs where the cancer might have spread. These are helpful for determining the stage of the cancer and in determining whether surgery is a good treatment option. CT scans can also be used to guide biopsy and a biopsy sample is usually removed and looked at under a microscope.

Like computed tomography (CT), a contrast agent may be injected into a patient’s vein to create a better picture.

This radioactive substance gives off energy which in turn is used to produce the images. PET can provide more helpful information than either CT or MRI scans. It is useful to see if the cancer has spread to the lymph nodes and it is also useful for your doctor to locate where the cancer has spread.
- Chest X-ray: This plain x-ray of your chest may be done to see if the cancer has spread to your lungs.
- Whole Bone Scan: The goal of a whole body bone scan is to show if a cancer has metastasized to your bones.
When to seek urgent medical care
Call your health care provider if symptoms of kidney cancer develop. If you experience either of the following symptoms, seeking urgent medical care as soon as possible:
- Severe low back pain or abdominal pain
- A large amount of hematuria
Treatment options
Patients with kidney cancer have many treatment options. The selection depends on the stage of the tumor. The options are surgery, radiation therapy, chemotherapy, biologic drugs treatment, or a combination of these methods. Before treatment starts, ask your health care team about possible side effects and how treatment may change your normal activities. Because cancer treatments often damage healthy cells and tissues, side effects are common. Side effects may not be the same for each person, and they may change from one treatment session to the next.

Prevention of kidney cancer
Although the reasons for the development of kidney cancer are not clear, epidemic data shows the following intervention may help to reduce your risk of kidney cancer:
- Early screening and treating genetic and hereditary diseases
- Changing lifestyle: Quitting smoking and controlling weight.
- Decreasing exposure to job-related risk factors such as asbestos, cadmium, some herbicides, benzene, and organic solvents, particularly trichloroethylene.
- Early detection and control of hypertension
- Early treatment of advanced kidney diseases
- Taking medicine under the doctors' direction
What to expect (Outlook/Prognosis)
The outcome depends on:
- The stage of the cancer: the size of the tumor, whether the cancer has spread outside the kidneys.
