Early stage kidney cancer refers to kidney cancer that is only confined to the envelope of the kidney and has not yet invaded the adjacent tissues and organs. Stage I refers to a tumor confined to the kidney with a diameter of ≤7cm, while stage II refers to a kidney cancer >7cm, but has not broken through the kidney envelope. Current information shows that the cure rate of early stage kidney cancer can reach 85%, and the cure rate of stage I can even reach 96%. However, early stage kidney cancer still has the possibility of recurrence, so it must attract the attention of doctors and patients, and must be reviewed regularly. 1.How to detect kidney cancer in early stage: The factors of kidney cancer are related to obesity, hypertension, family history of tumor, smoking, occupational exposure, etc. Therefore, people with high risk factors should pay attention to them. The main symptom of kidney cancer is painless carnal hematuria, but once hematuria is detected, the patient’s kidney cancer is often not early. Therefore, the most important way to detect kidney cancer at an early stage is to have regular checkups, especially for people over 40 years old. The most common screening method is urological ultrasound or CT, and routine urine examination can also be performed, and tumor cells can be found in urine. 2.What treatment measures should be taken for early stage kidney cancer: The first treatment method for early stage kidney cancer is surgery, which is the only possible way to cure kidney cancer. After surgery, chemotherapy or targeted therapy can be taken according to the patient’s specific condition. The emergence of targeted therapy drugs has greatly improved the survival rate of kidney cancer. Chinese herbal medicine can also be adopted to improve the efficacy by enhancing the anti-tumor ability of the body. It is also very important to maintain a positive state of mind, which can significantly prolong the survival period of tumor patients. In conclusion, early kidney cancer treatment is very effective and many patients can be cured, but we should not take it lightly and should detect kidney cancer recurrence early through active review after surgery and deal with it timely.
