Kidney Cancer: Symptoms of Metastasis

Kidney cancer belongs to the number of urological diseases, to which men are especially vulnerable from 40 to 60 years. Women are much less likely to have kidney cancer. Symptoms, as a rule, do not disturb in the early stages of the patient, more often it happens already with metastases.

There are a lot of factors influencing the development of this disease, but the main ones are overweight, nicotine addiction, long-term estrogen hormone use by men, direct and constant contact with asbestos, work related to skin dressing and making products from it, as well as prolonged hemodialysis.

Symptoms of kidney cancer

Renal and extrarenal are those clinical symptoms that are observed in a patient with a diagnosis of "kidney cancer" . Symptoms are renal: they include hematuria , a tumor that can be palpated, and pain. It should be noted that the more symptoms a patient feels, the worse things are.

Usually the patient suffers from hematuria, which appears suddenly, without pain (while in other kidney diseases pain first appears), against a background of well-being. It has an intermittent flow with constantly decreasing intervals between bleeding. At the same time, the abundance of hematuria in the diagnosis of kidney cancer does not affect the stage of the disease and the size of the tumor: even if the tumor is small and the disease has not yet passed into the last stage, the volume of blood in urine may be large.

Another fairly common symptom in kidney cancer is pain in the lumbar region. Pain can be of different nature and severity, but the most dangerous is dull pain, in which a successful outcome is unlikely.

To extrarenal symptoms include fever (body temperature varies from 37 ° C to 39 ° C, while the patient is very fevered), deterioration in the general well-being of the patient (loss of appetite, general weakness appears, the patient loses weight). This is due to the fact that the body is poisoning with toxic substances (general intoxication). But do not forget that the kidney cancer symptoms listed above, may not manifest. The appearance of anemia due to the effect of tumor formation toxins on the bone marrow indicates that the development of the tumor has gone irreparably far.

Depending on the location of metastases in the human body, kidney cancer symptoms can give different. Metastases in the lungs often lead to hemoptysis, in bone tissues to intense and persistent pain, which will hardly subside after taking painkillers or narcotics, in the spine lead to paralysis of the lower extremities and impairment of the functions of the pelvic organs.

Danger of metastasis

The kidney cancer cell has a light brown color. In shape and structure it is a granular, spindle-shaped, alveolar, solidly-tubular, polygonal cell. Its "sprouts", "claws" or metastasis spread through the water constituents of the human body through blood (hematogenous) or lymph (lymphogenous) and settle in the lungs, brain, bone tissues and liver cells. Often, the fastest clinically detect themselves is metastases. But even if the cancer tumor has been removed, there is no guarantee that in 10-20 years the kidney cancer will not appear again, the metastases of which will decide to manifest themselves.

At the same time, after elimination of the primary focus, pulmonary metastases sometimes tend to regress. Bony metastases are manifested mainly in the bones of the pelvis, femurs, spine, bones of the shoulder girdle, ribs and the cranial vault. The range of metastatic lesions is wide - lymph nodes, subcutaneous and circumferential fatty tissue, abdominal muscles and even postoperative scars.
