Transparent cell carcinoma of kidney is not scary because it is the most common kidney cancer and has good prognosis in early stage, but there are serious types of it, so patients need to pay attention to it and have it treated as early as possible. The reason why renal clear cell carcinoma is not scary is because renal clear cell carcinoma is the most common in the histologic classification of renal cancer, accounting for 70% to 80% of renal cell carcinoma, and its prognosis is relatively good compared with other types of renal cancer. If radical surgery for renal cancer is performed at an early stage, a considerable number of patients can achieve a good prognosis, and the five-year survival rate can reach 90% to 95%. However, there are serious types of renal clear cell carcinoma, which are related to its stage, grading, severity of symptoms and patients’ own conditions. If its stage is later, grading is higher, symptoms are serious and patients’ own conditions are poor, the prognosis will be relatively poor. Patients who are not feeling well should consult a doctor for examination in a timely manner, and once diagnosed, treatment should be carried out at an early stage in order to achieve the goal of clinical cure.
