What is kidney cancer?
Renal cell carcinoma (RCC) is the most common solid tumor of the kidney. It accounts for 90% of all malignant tumors of the kidney.
There are different types of renal cancer, the most frequent being clear cell renal carcinoma and to a lesser extent the papillary subtype (types I and II) and chromophobe.
What are the risk factors for kidney cancer?
The main risk factors are smoking, obesity and hypertension (high blood pressure). Therefore, a healthy lifestyle is essential for prevention (weight loss, smoking cessation and increased physical activity).
What are the symptoms of kidney cancer and how is it diagnosed?
Renal cancer may be manifested by symptoms such as hematuria (presence of blood in the urine), pain in the lumbar region or impairment of the general condition. However, at present most renal tumors are discovered by chance in radiological explorations (abdominal ultrasound, CT), and their size is less than 4cm, which allows curative treatment and the preservation of healthy renal tissue. For this reason, periodic check-ups by a specialist in urology are recommended.
The treatment of malignant tumors of the kidney depends on the size, extent and location of the tumor within the kidney. In addition, the function of the contralateral kidney, the patient's general condition, age and the presence of other diseases are taken into account.
Surgery is the standard treatment for RCC, either by removal of the entire kidney (radical nephrectomy) or removal of the tumor while preserving the healthy part of the kidney (partial nephrectomy).
The choice of surgical technique depends on the characteristics of the tumor and the patient. For this reason, we emphasize the importance of periodic check-ups, which urological revisions periodical check-ups that allow early detection, a more effective treatment and a better prognosis.
