Symptoms and signs of renal cell carcinoma

First, when renal cell carcinoma develops to a certain stage, there will be hematuria, low back pain, abdominal mass and other symptoms. Some patients will also have hypertension, anemia, weight loss, cachexia, fever, polycythemia, abnormal liver function, hypercalcemia, hyperglycemia, increased erythrocyte sedimentation rate, neuromuscular disease, amyloidosis, galactorrhea, abnormal coagulation mechanism and other changes.

Second: most of the patients with renal cancer are asymptomatic renal cancer found during physical examination, which accounts for more than 50% - 60% of the total number of patients with renal cancer. Low back pain and hematuria are the most common symptoms in patients with symptomatic renal cancer, and a few patients come to the hospital with abdominal mass. 10% - 40% of the patients had paraneoplastic syndrome, including hypertension, anemia, weight loss, cachexia, fever, polycythemia, abnormal liver function, hypercalcemia, hyperglycemia, increased erythrocyte sedimentation rate, neuromuscular disease, amyloidosis, galactorrhea, abnormal coagulation mechanism, etc.

Third: the extrarenal manifestations of renal cancer are called "paraneoplastic syndrome", which mainly include hypertension, anemia, weight loss, fever, polycythemia, abnormal liver function, hypercalcemia, hyperglycemia, increased erythrocyte sedimentation rate, neuromuscular disease, amyloidosis, galactorrhea, abnormal coagulation mechanism, etc. In addition, some patients with metastatic renal cell carcinoma may show bone pain, fracture, cough, hemoptysis and other symptoms caused by tumor metastasis.

matters needing attention

Diet should pay attention to low salt diet, eat light and vitamin rich food. Those with severe edema and hypertension should avoid salt, limit the amount of protein food and drink less water.
