What is kidney cancer? »Its definition and meaning

Also known as kidney cancer, it is blood in the urine, pain in one flank and the appearance of an abdominal mass. This triad is known as the too late triad, because by the time the patient exhibits all three symptoms, the disease has advanced beyond a cure point. Currently, most kidney tumors are asymptomatic and are accidentally detected during an imaging or X-ray examination, usually looking for unrelated causes. Other signs may include:

Abnormal color of the urine (brown, reddish, copper, etc.) due to the appearance of red blood cells in the urine.

Weight loss and undernourished appearance.

The main symptom may be due to metastatic disease, such as pathological fracture of a bone due to bone spread.

Varicocele or enlargement of a testicle due to blockage of the gonadal vein, usually on the left side due to compression by the tumor of the renal vein - the gonadal vein drains directly into the inferior vena cava.

Vision abnormalities.

Paleness from hypovolemia.

Hirsutism: excessive hair growth, mainly in women.

Constipation.

Arterial hypertension.

Elevated calcium levels (hypercalcemia).

Renal cell carcinoma is the most common form of kidney cancer, especially in adults and older adults, originating from the renal tubules. E l Initial treatment is surgery because it has the peculiarity of being consistently invulnerable to radiotherapy and chemotherapy, although some cases have responded to immunotherapy.
