Do not ignore the RCC's "clues"

The cause of the incidence of renal cell carcinoma is not entirely clear, studies suggest that, through the renal excretion of chemical carcinogens can induce renal cell carcinoma. Hormones, radiation, viral infections, smoking, long-term use of non-phenacetin drugs, long-term exposure leaded material as well as certain chronic kidney disease, are related to the occurrence may be related to renal cell carcinoma. Therefore, in peacetime to develop good habits, smoking, away from the sources, do not eat moldy rotten pickled food, light diet, to maintain patterns of life.

Location hidden kidney, kidney generally no obvious symptoms at an early stage, therefore, should pay special attention to the usual physical examination, from the age of 30-40, they should accept the conventional B-ultrasonic examination of kidneys. In fact, each year a considerable number of clinical patients with renal cell carcinoma through the B-examination and discovered their bodies at this time without any symptoms. Which are found in kidney cancer screening by physical examination are in early stage tumors, timely treatment is often a good prognosis.



Are the three major symptoms of renal cell carcinoma

Over the years hematuria, pain, swelling known as the "three symptoms of renal cell carcinoma," but this is not at the same time the three major symptoms appear. No typical symptoms of early renal cell carcinoma, 40 years old found urinating blood, should be checked in time.

B-scan can be found in the tumor than 1 cm in diameter; X-ray can see the increase in kidney shape contour; CT examination can be found in asymptomatic or cause renal pelvis, calyceal changes in renal cell carcinoma, and the accurate determination of mass density, size and staging; magnetic resonance imaging is the ideal means of checking the kidney can increase the identification rate of renal cell carcinoma; can be done urinary bladder vein or retrograde contrast microscopy and so on.

In addition to regular medical examinations, the hematuria is the most common symptoms of kidney cancer, multiple expressed as painless, intermittent episodes of hematuria. Hematuria unrelated to the size of the degree of kidney volume, it only shows the renal pelvis or renal cancer has invaded a small lamp. When the peripheral nerve tissue kidney tumor invasion only when the back pain occurs. Should be noted that urinary tract stones, inflammation, polyps will appear hematuria, but they have different symptoms, stones and polyps occur when severe colic hematuria; inflammation hematuria have bladder irritation symptoms occur, such as urinary frequency, urinary urgency, urine pain.

In addition, do B-inspection, if found within the kidney mass, and renal cysts but also differences. In general, renal cell carcinoma is a solid mass, the edge is not clear; renal cysts as cystic mass, the edge clear.
