Early detection methods for kidney cancer

Everyone knows that the early symptoms of kidney cancer are the same as other cancers, which are non-specific and the symptoms are not obvious. If the patient does not have the habit of regular physical examinations, it is difficult to detect the disease. By the time the symptoms are obvious, the best time for treatment will have been missed. Therefore, developing the habit of regular physical examinations has a positive significance for the treatment of the disease.

The most common and simplest way to check for kidney cancer is the general test method. Symptoms of hematuria can usually be detected. Polycythemia often occurs in 3 to 4 percent; progressive anemia kidney cancer may also occur. In bilateral renal tumors, total renal function usually does not change, and the erythrocyte sedimentation rate will be checked for increased. Some patients with kidney cancer do not have bone metastasis, but may have symptoms of hypercalcemia and increased serum calcium levels. After kidney cancer resection, the symptoms are quickly relieved and blood calcium returns to normal. Sometimes it can develop into liver dysfunction, which can return to normal if the kidney cancer tumor is removed. In addition, renal artery angiography can detect tumors that are not deformed by urinary system angiography, showing new blood vessels, arteriovenous fistulas, and increased contrast agent pool-like aggregated capsule vessels. It will be found that the angiography is highly variable, and sometimes kidney cancer may not be developed.

In addition, there are some other high-tech inspections, and these detection methods require the use of some high-end instruments.

1. Intravenous urography is a conventional method. It cannot show tumors that have not yet caused the renal pelvis and calyces to deform, and it is difficult to distinguish whether the tumor is renal cancer. However, intravenous urography can understand the function of both kidneys and the condition of the renal pelvis, calyces, ureters and bladder, which has important reference value for the examination of renal cancer.

2. CT scan: CT plays an important role in diagnosis. It can detect renal cancer without changes in the renal pelvis and calyces and without symptoms. It can accurately measure tumor density and can be performed in outpatient clinics. CT can accurately stage. Some people have calculated its diagnostic accuracy: 91% of invasion of the renal vein, 78% of spread around the kidney, 87% of lymph node metastasis, and 96% of involvement of nearby organs. CT examination shows a mass in the renal parenchyma, which can also protrude from the renal parenchyma.

Early detection methods for kidney cancer: After the above introduction, I hope everyone will have some understanding of the detection methods for kidney cancer and some detection items that need attention. Only in this way can kidney cancer be discovered in time, actively controlled, and further deterioration of kidney cancer can be prevented.
