1. Hematuria
Painless gross hematuria is the most typical symptom of kidney cancer, caused by tumor invasion of the collecting system, and may be intermittent.
2. Flank pain
Persistent dull flank pain due to tumor enlargement stretching the renal capsule or invading surrounding tissues; pain may radiate to the abdomen.
3. Abdominal mass
A firm, irregular, poorly mobile mass may be palpable in the upper abdomen and is one component of the classic late-stage triad.
4. Systemic symptoms
Unexplained fever, night sweats, fatigue, and weight loss, related to tumor-associated pyrogen release or absorption of necrotic tissue.
5. Paraneoplastic syndromes
Ectopic hormone production may cause hypertension, hypercalcemia, and polycythemia; these manifestations may improve after tumor removal.
6. Metastatic symptoms
Advanced disease may metastasize to bone, lung, and liver, causing bone pain, cough, hemoptysis, and right upper quadrant pain.
7. Varicocele
A left-sided varicocele that does not resolve in the supine position may result from tumor compression or tumor thrombus obstructing the left internal spermatic vein.
8. Lower-limb edema
Compression of the inferior vena cava or tumor thrombus can impair venous return, indicating extensive progression and an unfavorable prognosis.
Jinshazhou Hospital of Guangzhou University of Chinese Medicine emphasizes that kidney cancer is a common urinary tract malignancy with insidious early symptoms and significant health impact. Early detection and standardized treatment can markedly improve cure rates. The public should remain vigilant for the classic triad of painless hematuria, flank pain, and abdominal mass and seek prompt medical evaluation. Regular health examinations and healthy lifestyle practices are important measures for addressing kidney cancer.
