With the influence of bad living habits, the incidence rate of cancer is getting higher and higher, such as stomach cancer, lung cancer, bowel cancer, kidney cancer, etc. This article will introduce you the characteristics of renal cancer, the spread and metastasis of renal cancer, and some common sense to prevent renal cancer. I hope it will help you.
What are the characteristics of renal cancer
In addition to physiological reasons, the high incidence of male renal cancer is closely related to male smoking, excessive social intercourse and high life pressure. Some studies have shown that smokers are twice as likely to suffer from kidney cancer as non-smokers, and the longer they smoke, the greater the amount of smoking, the higher the risk. The reason is related to the chronic stimulation of various toxic substances in tobacco to the body.
In addition, men socialize more for work reasons, and long-term high-fat and high-calorie diet will not only lead to obesity, hypertension, etc., but also increase the risk of kidney cancer. Therefore, quitting smoking, eating less high-fat and high-calorie foods such as fish and meat, fried foods, and actively controlling weight can help prevent kidney cancer.
In order to detect renal cancer at an early stage, men over the age of 40 insist on annual B-ultrasound examination of their kidneys, especially men with poor lifestyle and family history of renal cancer. Clinically, 50% of patients with early asymptomatic renal cancer were found through physical examination.
Among them, B-ultrasound is one of the most suitable methods for screening renal cancer, which can detect renal tumors with diameters of 0 and 8 cm. In case of abnormalities found by B-ultrasound, CT examination should be performed. This method can detect tumors of 0 or 5 cm or more, and MRI should also be performed for those who still cannot be diagnosed.
If the patient has three typical symptoms of kidney cancer: low back pain, hematuria, and mass, it indicates that the disease has developed to the middle and late stage, and its low back pain is persistent dull pain. If the tumor invades the nerve or lumbar spine, it can cause severe pain. When hematuria coagulates into cord-like blood clots in the ureter, it can also cause low back pain. In addition, renal cancer can also cause fever, anemia, emaciation, abnormal liver function, etc. Unfortunately, renal cancer has no obvious symptoms at the early stage, so the importance of early physical examination should be emphasized.
Through the introduction of the above content, you have some understanding of the cause of renal cancer. Once suspected symptoms appear, it is better to go to a regular professional nephrotic hospital for diagnosis and treatment. Finally, remind the majority of patients to thoroughly understand their changes in their condition, understand the cutting-edge treatment methods of kidney disease, and conduct standardized treatment at an early stage, so as to avoid delaying the disease and causing irreparable losses.
Dissemination and metastasis of renal cell carcinoma
1. Direct dissemination
Direct dissemination can pass through the renal capsule to the surrounding tissues or invade the renal vein and the inferior vena cava. If it invades the kidney, hematuria may occur clinically. At the same time, renal cancer can also invade the colon, pancreas, adrenal gland, peritoneum, liver, spleen and other surrounding tissues.
2. Lymphatic metastasis
Renal carcinoma has 15% - 30% metastasis through lymphatic pathway. The left side metastasis to the renal pedicle, anterior aortic and left lymph nodes, the lateral involvement of the lymph nodes near the renal hilus, anterior inferior vena cava, and the lymph nodes between the aorta and inferior vena cava, and the upward metastasis to the neck can cause neck lymph nodes swelling, etc
3. Hematogenous metastasis
The tumor invades the renal vein and causes the formation of tumor thrombus in the vein, which can be transferred to the lung, liver, bone, etc. At the same time, the tumor thrombus can be retrograde extended from the renal vein to the internal spermatic vein (tendril plexus), or the ovarian and internal vaginal veins, resulting in the metastasis of spermatic cord, epididymis, broad ligament of uterus, vagina, labium, etc. The incidence of metastasis of cancer cells to renal vein and inferior vena cava was 20% and 10% respectively.
These are the common ways of renal cancer metastasis. You must follow the doctor's instructions when treating renal cancer. You should also pay attention to the diet during the treatment. At the same time, a good attitude can also play a very good role in treating renal cancer. You must be careful. Next, let's introduce some common sense to pay attention to in the prevention of renal cancer.
Some common sense for prevention of renal cancer
Many people have kidney cancer without realizing it. This is a very serious kidney disease, which is more harmful than uremia. So, what causes this disease? Nephrology experts pointed out that the occurrence of renal cancer is closely related to obesity. In addition, there are some other factors. Let's take a look.
According to the new research, for both men and women, maintaining normal weight can reduce the incidence of renal cancer, while being overweight will increase the risk of renal cancer. Researchers found that the risk of renal cell carcinoma caused by overweight was the same for both men and women. Compared with normal weight people, morbidly obese people have twice the risk of kidney cancer, twice the risk of obesity, and 35% higher than overweight and non-obese people. Researchers said: It may be that the level of some hormones (such as insulin) in obese people increases, which promotes the growth of renal cell carcinoma; or it may be that obesity affects the blood supply of the kidney, making the kidney more sensitive to carcinogens. The following aspects should be done well in the prevention of renal cancer:
1. Quit smoking and don't drink too much.
2. Avoid radiation damage and use hormone with caution. Strengthen the protection against contact with lead compounds. Reducing the exposure of chemical carcinogens is an important measure to prevent this disease.
3. Use antipyretic drugs with caution.
4. Actively carry out cancer prevention publicity, popularize cancer prevention knowledge, and achieve early diagnosis and treatment of renal cancer, which is the key to determine the treatment effect and prognosis of this disease.
5. Patients with renal diseases such as renal cysts should be actively treated.
6. Take part in physical exercise regularly to keep a happy mood and increase body immunity.
7. Eat a low-fat diet and fast animal fat. Control weight and prevent kidney cancer after obesity.
8. Drinking green tea has good cancer prevention effect.
9. Postoperative rehabilitation patients should be re-examined regularly, every 1-3 months, and those in good condition should be re-examined every six months to a year, and adhere to the treatment.
These are the common causes of renal cancer. We must do a good job in the prevention of this disease. A healthy body is the greatest cost of a person. How to prevent kidney disease is particularly important in daily life. Good eating habits and hygiene habits can prevent any disease.
