Kidney Cancer: Symptoms of Metastasis

Kidney cancer belongs to the number of urologicaldiseases, which are especially affected by men 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.

Factors affecting the development of this diseasequite a lot, but the main ones are overweight, nicotine addiction, long-term estrogen hormone intake by men, direct and constant contact with asbestos, work associated with 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 "Kidney cancer". Symptoms are renal: they are 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, whichappears suddenly, without pain (while in other kidney diseases pain first appears), against a background of well-being. It has an intermittent course with ever-decreasing intervals between bleeds. In this case, the abundance of hematuria in the diagnosis "kidney cancer" stage of the disease and the size of the tumor does not affect: 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 commonsymptom in kidney cancer are pain in the lumbar region. Pain can be of different nature and severity, but the most dangerous is blunt pain, in which a successful outcome is unlikely.

Extrarenal symptoms include fever(body temperature varies from 37 ° С to 39 ° С, thus the patient strongly fever), deterioration of the general state of health of the patient (appetite is lost, there is a general weakness, 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 effects of tumor formation toxins on the bone marrow indicates that the development of the tumor has gone irreparably far.

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

Danger of metastasis

A cell of a malignant tumor of the kidney haslight brown color. In shape and structure it is a granular, spindle-shaped, alveolar, solidly tubular, polygonal cell. Its "sprouts", "claws" or metastases 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 old kidney cancer will not appear again, the metastases of which will decide to manifest themselves.

At the same time, after removal of the primary focuspulmonary metastases sometimes tend to regress. Bone 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 post-operative scars.
