The symptom when kidney cancer discovers?

summary

Renal cell carcinoma (RCC) is a malignant tumor originated from the renal parenchymal urothelial system. It is also known as renal adenocarcinoma. It includes various subtypes of renal cell carcinoma originating from different parts of urinary tubules, but does not include tumors originating from renal interstitium and renal pelvis. Let's have a look.

The symptom when kidney cancer discovers?

Renal cell carcinoma (RCC) is a malignant tumor originated from the renal parenchyma and urinary tubular epithelial system, accounting for 2% - 3% of adult malignant tumors. At present, the incidence rate is around 6.0/10 million, and about 78 thousand of new patients are in the country every year. Of them, 25% are advanced patients, and males are higher than females. The highest incidence is 50~70 years old. The etiology of renal cancer is complex. According to epidemiological investigation, some renal cancer is related to smoking, obesity, hypertension, kidney disease, some industrial substances, aflatoxin, hormone and radiation. In addition, there are some genetic factors.

Due to the hidden location of the kidney, lack of typical clinical manifestations in the early stage, renal cell carcinoma with symptoms is often in the advanced stage. In recent years, the majority of patients with renal cell carcinoma are asymptomatic renal cell carcinoma found in the health examination, these patients account for more than 50% - 60% of the total number of patients with renal cell carcinoma. Low back pain and hematuria are the most common symptoms in patients with symptomatic renal cancer, and a few patients come to hospital with abdominal mass. Some patients also accompanied with hypertension, anemia, weight loss, fever, polycythemia, liver dysfunction, hypercalcemia, hyperglycemia and so on. If the tumor metastasis, may also appear bone pain, fracture, cough, hemoptysis and other symptoms.

The clinical diagnosis of renal cell carcinoma mainly depends on imaging examination, and the final diagnosis needs pathological examination. B-ultrasound is the simplest way to screen renal cancer without any harm to the body. Now the level of examination is constantly improving, and some renal tumors of 1-2 cm can also be found, so patients can make further examination accordingly. The commonly used imaging examinations include abdominal CT, abdominal MRI, chest X-ray (anteroposterior and lateral) and so on.

matters needing attention

Thus, once renal cancer disease occurs, patients will appear mass pain and hematuria and other diseases, if the three complete, the course of disease is more advanced; Generally at an earlier stage, there are only one or two of them.
