Renal clear cell carcinoma is a type of renal cell carcinoma with abundant cytoplasm and abundant capillaries in the interstitium under the microscope. Risk factors include smoking, obesity, hypertension, diet, occupational exposure (e.g. aromatic compounds, etc.), genetic factors, etc. The main symptom is intermittent hematuria.
Renal clear cell carcinoma accounts for 70-80% of renal cell carcinoma, and microscopy shows that the tumor cells are polygonal or round, relatively large in size, with rich cytoplasm, granular or transparent, and with abundant blood sinusoids and capillaries in the interstitium.
Smoking is the most important risk factor for renal cell carcinoma, and the incidence rate of renal clear cell carcinoma in smokers is twice as high as that in non-smokers. Early symptoms of renal cell carcinoma are not obvious, and the tumor size is already relatively large when it is found. Its main symptom is intermittent painless hematuria, which is typically characterized by low back pain, lumps in the kidney area and hematuria.
Patients with renal clear cell carcinoma should follow the doctor’s instruction for active treatment.
