What are the characteristics of renal cell carcinoma, how to diagnose

Many types of renal tumors, but most malignant poor prognosis complex pathology, clinical mixed, with the most common kidney cancer, renal cancer about 85 percent, followed by transitional cell carcinoma of the renal pelvis and Nephroblastoma, etc. . RCC also known as renal cell carcinoma, the high age of 40-65 years old, men more than women. Originated in renal tubular epithelial cells, can occur in any part of the renal parenchyma, but more under extremely Most of the minority transgression, and the entire kidney; left renal disease equal opportunity, bilateral lesions of the 1% 1 2%. Patients with renal cell carcinoma diagnosed after more than a year without treatment, died within 2-5 years of individual survival. There are many factors that affect the prognosis of early stage, cell differentiation, and timely, reasonable and uphold for a long time, the combination of traditional Chinese and western medicine treatment, the better the prognosis, contrary poor. The incidence of renal cell carcinoma cause unclear, the study by renal excretion of carcinogenic chemical substances can induce kidney, hormones, radiation, infection, smoking, long-term use of non-phenacetin drugs, long-term exposure to certain substances, as well as lead those with chronic kidney disease may be related to the occurrence of renal cell carcinoma. The clinical manifestations of renal cell carcinoma variety, and sometimes without any symptoms, but the tumor in the body has been extensive progress, and even lung, bone metastasis and other features. Hematuria, flank pain and the mass in the clinical often called the three typical symptoms of renal cell carcinoma. (1) Hematuria is the most common symptoms, frequently manifests itself intermittent, painless naked eye and / or microscopic hematuria. (2) persistent low back pain frequently manifests itself Duntong. When the tumor has invaded or spinal nerve can cause severe pain. Hematuria in the ureter into the solidification cable Strip blood clots, with the discharge of urine, can cause lumbar pain. (3) mass in patients with renal cell carcinoma waist or abdominal mass can be touched, about 10 per cent. In the initial formation of kidney tumors difficult to contravene that, only grow to more than 3-5 cm in diameter, can be in the palpation when touched. Masses of often hard, rugged surface, or nodular. Or wasting in patients with renal tumors in the very, palpable to the physical mass. If mass fixed that renal around infiltration, poor prognosis. Above three symptoms of the few opportunities at the same time, about 10% of a 15%, at the same time if the signs are often late. The RCC is a highly malignant tumors, many patients, has been obvious emaciated, anemia, fever, anorexia, and other physical evil disease. Patients can be left with a minority of varicocele. As the inferior vena cava involvement, may be associated with lower extremity edema. If the transfer of the lung or bone, there will be corresponding symptoms. The large number of clinical observation revealed that some patients with renal cell carcinoma can also be associated with endocrine disorder symptoms. This is because the kidney to a variety of endocrine secretion of, which led to a series of corresponding symptoms. For more than 50 years old in age, and there are three main symptoms of fever and unidentified persons, and this should arouse a high degree of vigilance, take timely action to the relevant inspection, confirmed or ruled out as soon as possible. Items: (1) urine routine inspection. (2) urinary film. (3) renal artery and pyelography. (4) B-scan. (5) CT. (6) MRI. (7) radionuclide inspection.
