What are the clinical symptoms of kidney cancer

In recent years, kidney cancer has become one of the major diseases that endangers society and human health, and it has brought great pain and distress to humans. In order to reduce the incidence of kidney cancer, we humans should master the clinical manifestations of kidney cancer:

1. Hematuria:

Hematuria is often painless and intermittent. The whole process of hematuria is visible to the naked eye, and the interval shortens as the disease progresses. When renal cancer bleeds a lot, it may be accompanied by renal colic, which is often caused by blood clots passing through the ureter. The blood clots in renal cancer hematuria may form strips due to passing through the ureter. The degree of hematuria has nothing to do with the size of renal cancer. Renal cancer can sometimes present as persistent microscopic hematuria.

2. Low back pain:

Lumbar pain is another common symptom of kidney cancer. Most of the time, it is dull pain, localized in the waist. The pain is often caused by the growth of the tumor and the swelling of the renal capsule. Blood clots passing through the ureter can also cause lumbago as mentioned above. When the tumor invades the surrounding organs and waist muscles, the pain is more severe and persistent.

3. Lumps:

Lumps are also a common symptom. About 1/3 to 1/4 of kidney cancer patients can be found with enlarged kidneys when they seek medical attention. The kidneys are relatively hidden, and lumps are difficult to detect before kidney cancer reaches a considerable size. Generally, a lump felt in the abdomen is a late-stage symptom.

4. Pain:

Pain occurs in about 50% of cases and is also a late symptom. It is caused by the renal capsule or renal pelvis being involved by a gradually growing tumor, or by the tumor invading and compressing the connective tissue, muscles, lumbar vertebrae or lumbar nerves on the posterior abdominal wall, resulting in persistent pain in the affected side of the waist.

The above are the clinical manifestations of kidney cancer.
