What are the symptoms of advanced kidney cancer

What are the symptoms of advanced kidney cancer?

Renal cancer is common in men aged 40 to 70. The typical symptoms are pain, hematuria and a lump in the waist, but these symptoms may not occur until the tumor compresses the surrounding tissues, such as hematuria compressing the urinary system.

1. Hematuria: Intermittent hematuria, which shortens intermittently as the disease worsens. Hematuria may be painless or accompanied by renal colic, and blood clots in the urine are in the form of strips.

2. Lump: Nearly one-third of kidney cancer patients are found to have enlarged kidneys when they seek medical attention. Because the kidneys are relatively hidden, when a lump is felt in the abdomen, it means that the kidney cancer has reached a considerable size.

3. Low back pain: As the mass increases, the renal capsule or renal pelvis swells, and the tumor invades the surrounding organs, it compresses the posterior abdominal connective tissue, muscles, lumbar vertebrae and lumbar nerves, causing persistent dull pain in the lower back.

4. Varicocele: It mainly occurs in the infiltration of left renal solid tumors, compressing the left spermatic vein, and may also be the formation of spermatic vein cancer thrombosis. When varicose veins lie flat, varicose veins will not disappear.

5. Systemic poisoning symptoms: Weight loss is a common systemic symptom in patients with kidney cancer, accompanied by general discomfort, loss of appetite, depression, fatigue, etc.

6. Fever: Mostly low-grade, intermittent or continuous, some patients are diagnosed with kidney cancer due to high fever. Body temperature can return to normal after cancer surgery. In the past, it was believed that fever was caused by hemorrhage and necrosis in the tumor, but in recent years, it has been proven that there is a fever source in kidney cancer tissue.

7. Symptoms of renal cancer metastasis: There are generally three ways for renal cancer to metastasize, namely local invasive tumor, disseminated blood metastasis and lymph node metastasis.

In addition to the seven common symptoms mentioned above, there are some other symptoms of late-stage kidney cancer, such as fever, loss of appetite, fatigue, weight loss, anemia, cough, hemoptysis and other lung symptoms.

30% of kidney cancer patients suffer from a variety of mixed symptoms such as hypertension, hypoglycemia, hyperglycemia, and polycythemia before seeking medical treatment, which are valuable clues for discovering kidney cancer.
