What are the dangers of kidney cancer

Kidney cancer is a very serious malignant tumor disease. Once such a disease occurs, the harm is quite serious. For kidney cancer, we need to do a good job of scientific treatment when we are sick. Correct and scientific treatment is very important. Let's understand what kind of harm does kidney cancer have? Let's take a look at the editor's detailed introduction.

Kidney cancer can cause great harm to patients. 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 kidney 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 hematuria may form strips due to passing through the ureter. The degree of hematuria has nothing to do with the size of kidney cancer. Kidney cancer can sometimes manifest as persistent microscopic hematuria.
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.
Mass is also a common symptom. About 1/3 to 1/4 of patients can find enlarged kidneys when they seek medical treatment. The kidneys are hidden, and it is difficult to find a mass before kidney cancer reaches a considerable size. Generally, if a mass is felt in the abdomen, it is already a late symptom. 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 the gradually growing tumor, or by the tumor invading and compressing the connective tissue, muscles, lumbar vertebrae or lumbar nerves on the affected side, resulting in persistent pain in the lower back.
