What are the symptoms of a left kidney tumor?

The main symptoms of left kidney tumors include the following aspects: 1. Low back pain and discomfort: Tumor growth can cause increased pressure in the kidney area, leading to back pain, which may intensify as the tumor enlarges. 2. Hematuria: When the tumor invades the renal mucosa or ruptures spontaneously, blood may mix with the urine, causing hematuria, which could be an obvious sign of a malignant tumor. 3. Abdominal mass: As the tumor increases in size, patients may feel a mass in the abdomen, which may be accompanied by tenderness or a fluctuant sensation. 4. Other symptoms: In addition to the above symptoms, left kidney tumors may also cause other nonspecific symptoms such as frequent urination, urgency, painful urination, general fatigue, weight loss, and fever. It should be noted that the presence of the above symptoms does not necessarily indicate left kidney tumor; however, persistent symptoms should raise the patient's concern, and timely medical consultation for detailed examination is recommended.
