Precancerous renal symptoms are not obvious, but in advanced stages of the disease, the tumor can compress the renal envelope or pull the renal pedicle, causing lumbar acidity, swelling, and pain.
At present, kidney cancer accounts for about 80%-90% of adult malignant tumors, it is the most common disease in adults, the ratio of men to women is about 2:1, and it is easy to develop diseases at all ages, of which 50-70 years old have the highest incidence.
Since there have been more and more kidney cancer patients in recent years, it has to attract people's attention, and once the body has the following 5 changes, it is necessary to suspect this disease.
First, painless gross hematuria
Early kidney cancer tumors are small and do not invade the renal pelvis, renal envelope, and other organs, so most are asymptomatic.
But when the tumor develops to a certain stage, the patient will begin to have corresponding symptoms, and hematuria is the first signal;
This is due to the inability of kidney function to filter red blood cells or the appearance of symptoms of blood clotting, as well as the presence of red blood cells in the urine. Therefore, when there is such a performance, it is necessary to arouse people's vigilance.
Second, low back pain symptoms
Every kidney cancer patient will have a low back pain reaction because the kidneys in the human body are very close to the waist.
Therefore, low back pain is another common symptom of kidney cancer, most of which is vague pain, limited to the waist, if the lump continues to increase, the kidney envelope is swollen severely, and the pain will become more and more serious.
Especially when the mass passes through the ureter, the cancer cells are likely to affect the surrounding organs and the psoas major muscles, causing more harm.
Third, the systemic reaction
Left renal tumors may be accompanied by secondary left varicocele due to tumor invasion of the inferior vena cava, resulting in lower extremity edema.
This reaction often occurs in patients with metastatic conditions, and if left uncontrolled, about 43% of patients have a variety of reactions such as hypertension, weight loss, anemia, low fever, poor appetite, and weightlessness.
Fourth, the lump arises
In general, patients will have lumps in the waist or abdomen, which is caused by the advanced progression of the disease.
Therefore, about 1/3 to 1/4 of patients with advanced kidney cancer will find kidney enlargement when they see a doctor, but the lump of renal cell carcinoma is difficult to find when it has not developed to a certain volume.
Therefore, the lump is an advanced symptom, and patients must understand it clearly.
Fifth, paraneoplastic syndrome
Literally, it means tumor-associated syndrome, mainly due to the proteins produced and secreted by renal cell carcinoma entering the bloodstream, causing a variety of symptoms.
Initially, hypercalcemia is elevated calcium in the blood, leading to physical weakness, slow response, and altered mental status. There is also polycythemia, which refers to an increased red blood cell count (as opposed to anemia), which can lead to blood clotting or embolism.
In addition to the above several conditions, diabetes can not be ignored, refers to blood sugar beyond the normal range, the incidence of 10% to 20%, and hypertension, and renal cell carcinoma (such as renin) secretion of hormones related, renin continues to increase, not only affect blood pressure, but also cause liver function damage.
The kidney is one of the important organs of the human body, and the kidney function contributes to the metabolism of waste products in the body, which is of great significance for the normal operation of the human body.
Therefore, in order to prevent kidney cancer and other diseases that affect kidney function, patients should minimize the burden on the kidneys in their daily lives and undergo regular physical examinations.
After all, there are still many people who do not understand this disease, let alone the related diseases, so it is difficult to detect the disease at an early stage, thus delaying the best time to improve the disease.
