What are the common symptoms of kidney cancer?

The incidence of kidney cancer has always been high in China, and the symptoms of kidney cancer vary. Therefore, many patients delay timely treatment of the disease because they do not understand the symptoms of kidney cancer. So, what are the symptoms of kidney cancer ? Let's take a look at how experts answer the question of kidney cancer symptoms.

Symptoms of kidney cancer include:

1. Symptoms of endocrine disorders: According to a large number of experimental studies and clinical reports, renal cancer can secrete a variety of endocrine hormones to cause a series of symptoms. The secretion of multiple endocrine hormones by a tumor is a characteristic of renal cell carcinoma. A small number of renal cancers are complicated by increased gonadotropin, which causes breast enlargement, areola pigmentation and decreased libido in men, and hirsutism and amenorrhea in women.

2. Symptoms caused by local tumors: Hematuria is the most common symptom of kidney cancer, which can be macroscopic hematuria and/or microscopic hematuria. Lumbar pain occurs when the tension of the renal capsule increases or invades surrounding tissues after the tumor grows. It manifests as persistent dull pain. About 10% of kidney cancer patients can feel a mass in the waist or upper abdomen, which can sometimes be the only symptom. Varicocele often occurs on the left side, caused by the compression of the spermatic vein by the tumor. It is a secondary lesion. Varicose veins do not disappear after lying flat, indicating that there is obstruction (or cancer thrombus) in the vein. When the inferior vena cava is invaded, lower limb edema may also occur.

3. Systemic toxicity symptoms: Since kidney cancer is a highly malignant tumor, many patients have obvious cachexia such as weight loss, anemia, low fever, loss of appetite when they seek medical treatment, and may also have lung or bone metastasis. Fever is one of the common extrarenal manifestations of kidney cancer, with low fever or high fever. High fever can be as high as 39~40℃ and persist. Anemia can be caused by blood loss, but clinically some kidney cancer patients have no history of hematuria but have obvious anemia, indicating that the patient's anemia is caused by other reasons besides hematuria, which may be related to tumor toxins or a large amount of kidney tissue destruction that inhibits hematopoiesis.
