What are the complications of kidney cancer?

What are the complications of late-stage renal cancer? Back pain: Back pain is another common complication of late-stage renal cancer. Most cases are dull pains, localized to 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 back pain as mentioned above. When the tumor invades the surrounding organs and the waist muscles, the pain is more severe and persistent.

Hematuria: A complication of late-stage renal cancer. 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.

Pain: Pain is a late-stage complication of renal cancer that occurs in about half of cases. It is also a late-stage symptom. It is caused by the renal capsule or renal pelvis being pulled by the 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.

Mass: Mass is also a common complication of late-stage renal cancer. A small number of renal cancer patients may have enlarged kidneys when they seek medical treatment. The kidneys are relatively hidden, and masses are difficult to detect before renal cancer reaches a considerable size. Generally, if a mass is felt in the abdomen, it is already a late-stage symptom.

Other symptoms: fever of unknown cause, or metastasis when just discovered, fatigue, weight loss, loss of appetite, anemia, cough, hemoptysis and other lung symptoms. In addition, the effects of renal adenocarcinoma are caused by the endocrine activity of the tumor, including polycythemia, hypertension, hypotension, hypercalcemia, and fever syndrome. Although these systemic, toxic and endocrine effects are non-specific, about 30% of patients first have many mixed manifestations. Therefore, it is a valuable clue, and this finding is considered to be a systemic effect of the tumor.

Don't be too nervous and think that your disease may be particularly difficult to treat. I believe that as long as we can actively cooperate with the doctor's treatment to a great extent and go to a regular hospital for relevant follow-up examinations, I believe you will recover soon.

The main hazard of kidney cancer is hematuria: Normal people will not have hematuria, but this is the main symptom of kidney cancer patients. About 40% of kidney cancer patients have hematuria, which can be macroscopic hematuria or microscopic hematuria. When there is a large amount of hematuria with blood clots, renal colic, urination pain, urination difficulty, and even urine retention may occur.

Mass: Kidney cancer is a malignant tumor, and because it is close to the waist, the mass can be clearly felt. The kidney is located deep behind the peritoneum and cannot be felt during abdominal palpation. The mass can only be felt when the tumor is large or located at the lower pole of the kidney. A small number of patients can feel an abdominal mass, which can sometimes be the only symptom.

In addition to hematuria and lumps, the harm of kidney cancer also includes pain. Severe pain is the biggest hidden danger for kidney cancer patients. Low back pain occurs when the tension of the renal capsule increases or invades surrounding tissues after the tumor grows, and it manifests as persistent dull pain. Tumor bleeding causing subcapsular hematoma may also cause dull pain or dull pain. Tumor invasion of adjacent tissues and organs such as the psoas major muscle or nerves can cause persistent and severe low back pain, which occurs in most cases. If there are related symptoms, you should seek medical attention in time to avoid delaying the disease.

Fever of unknown etiology, or when the patient is already moving when first diagnosed, pulmonary symptoms such as fatigue, weight loss, loss of appetite, anemia, cough and hemoptysis. Other symptoms of renal adenocarcinoma are caused by tumor endocrine activity, including polycythemia, hypertension, hypotension, hypercalcemia, and febrile syndrome. However, these systemic, toxic and endocrine symptoms are non-specific, but about 30% of patients initially have a large number of mixed manifestations. Therefore, it is a valuable clue that this manifestation is considered to be a systemic function of the tumor.
