What are the hazards of advanced kidney cancer in the elderly

Kidney cancer is a major malignant tumor that endangers people's lives. Many people do not know much about the late-stage symptoms of kidney cancer, which leads to the disease being unable to be treated after it is discovered. So what are the late-stage symptoms of kidney cancer in the elderly? The following is a detailed introduction by experts from the Kidney Hospital:

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 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 kidney cancer 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.
2. Pain: Pain occurs in many people and is also a symptom of late-stage renal cancer. It is caused by the renal capsule or renal pelvis being pulled 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.
3. Lumbar 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.
In addition, the effects of renal carcinoma are caused by tumor endocrine activity, including polycythemia, hypertension, hypotension, hypercalcemia, and febrile syndrome. Although these systemic, toxic, and endocrine effects are non-specific, a few patients initially have many mixed manifestations.
