Renal cell cancer

Renal cell cancers are also referred to as renal carcinoma or adenocarcinoma of the kidney. They account for around 95 percent of all kidney tumours and originate mostly in the cells of the urinary tract.

Renal cell cancer is caused by a degeneration of the tubule cells in the renal cortex. They account for about two percent of all malignant tumours in adults. The peak age is between 45 and 65. Currently, about six to seven people per 100,000, more often men than women, contract the disease every year.


The possible causes of renal cell cancer include changes in scarring, excessive consumption of painkillers and smoking.



Renal cell cancer presents no discomfort to the patient over a long period of time, so it is often only detected at an advanced stage. Classic symptoms are blood in the urine (which is painless for the patients) and pain in the kidney or side. However, these are not early, but late symptoms! One third of patients already have metastases at the time of diagnosis.

More than half of all kidney tumours are identified through other symptoms such as high blood pressure and back pain or symptoms of metastases that have already appeared in various organs. If blood clots obstruct the urinary tract after bleeding from a tumour, kidney colic can also be the first symptom. In later stages of the disease, patients report a loss of energy, weight loss, night sweats and sometimes fevers.

An ultrasound is the first step towards a more accurate evaluation of the kidney. It can also be used to perform punctures of abnormal growths in the kidney, which are then histologically assessed by the pathologist. Intravenous urography is an x-ray with a contrast medium that can be used in the kidneys to provide information about obstructed urine flow and to assess the function of the healthy kidney. Computer tomography of the abdomen is used to determine the spread of the tumour. X-rays of the chest (thorax) and, if necessary, a skeletal scintigraphy and a brain MRI (MRT) can be used to detect possible remote metastases.

Recommended therapies for the treatment of renal cell carcinoma:

Whole-body hyperthermia

For patients with renal cell carcinoma, the healing effect of whole-body hyperthermia is that we can quickly bring the organism up to high temperatures (up to a maximum of 40.5 ° C). This rapid and intense warming not only activates the immune system, but kills many degenerated tubule cells of the renal cortex by suppressing the rate and rapid influx of heat. In addition to the damage or elimination of cancer cells, whole body hyperthermia activates the immune system enormously and does not pollute the organism. It causes an immune cascade, in which the white blood cells proliferate and activate.

Locoregional hyperthermia

Renal cell carcinoma is also recommended for regionally effective hyperthermia, the effect of which is to quickly heat the affected area to high temperatures (40 to 44 ° C maximum). This heating activates the immune system. In addition, many degenerated tubule cells of the renal cortex are damaged or killed. In our practice in the Hyperthermia Center Hannover we offer depending on the diagnosis of this partial body hyperthermia, in which targeted only damaged or degenerated tissue is overheated, which we guarantee our patients a very gentle treatment.

Gerson Therapy

The nutritional therapy according to Dr. Gerson aims to detoxify the body while adding lots of fresh nutrients, which is particularly helpful for patients with renal cell carcinoma. In addition to special juices, which are prepared fresh and elaborate and are taken regularly throughout the day, they contain essentially fresh, high-quality fruits and vegetables. This is prepared with special consideration of the healing power contained therein and partly prepared as fresh food, partly in special soups. The Gerson therapy is low in sodium, low in protein and low in fat.


For patients with renal cell carcinoma, the healing effect of oncolytic virotherapy is to destroy the cancer cells with the help of viruses. Virotherapy consists of several injections according to a predetermined virotherapy treatment plan, which is run at the Hyperthermia Centre Hannover by Dr. med. Mohamed Ali Zayen as a certified specialist in virotherapy RIGVIR®. Virotherapy is carried out on an outpatient basis and according to an individualized treatment plan. The longer a RIGVIR® virotherapy is continued, the longer the intervals become.
