What is small kidney cancer? Is there any difference between him and kidney cancer?

Small kidney cancer usually refers to kidney cancer less than 3cm, which is no different from kidney cancer, and its essence is kidney cancer, but because the lesion is still relatively small, the clinical manifestations, surgical methods and prognosis are different from larger kidney cancer.

The natural growth rate of small kidney cancer is mostly slow, and the patient's age, pathological grade, and tumor size at the time of initial diagnosis are relevant risk factors for the natural history of the disease. Small kidney cancer generally refers to cases in which the isolated tumour is smaller in diameter and has no other lymph node metastases. Patients with small kidney cancer generally have no clinical symptoms, and the tumor stage is early, and small kidney cancer is mainly found by abnormalities in B-ultrasound and other examinations in health examination.

Strengthening ultrasound screening in healthy people can contribute to the early detection and early detection of small kidney cancer. The diagnosis of small kidney cancer mainly depends on 8 ultrasound, CT, MRI and other imaging examinations, and their combination and comprehensive analysis can improve the diagnosis rate of small kidney cancer.

Small kidney cancer refers to the malignant tumor found in the kidney less than 4cm through imaging examination, such as B ultrasound and CT, and the small kidney cancer can be preserved in principle, that is, the kidney is not removed, but only the kidney cancer tissue is removed, which can save the kidney function to the greatest extent, and the possibility of acute renal failure after surgery is greatly reduced. Through long-term clinical observation, partial resection of kidney cancer less than 4 cm has no significant improvement in long-term survival rate compared with whole kidney and tumor tissue resection, so kidney preservation can be performed for patients with small kidney cancer**. Epidemiology also found that after partial resection of small kidney cancer, the probability of long-term metastasis** was the same as that after total resection of the same kidney, but the patient retained part of the kidney, especially the poor function of the contralateral kidney benefited more, so the method of small kidney cancer** was slightly different from that of kidney cancer.

There is no difference, more professionally, it should be early stage of kidney cancer. The first method of early kidney cancer is surgical resection, and ** nephrectomy should include the perirenal fascia, fat, kidney, adrenal and lymphoid tissues, and ureters.

Early manifestations of kidney cancer (1) Hematuria-** intermittent hematuria is a major feature of kidney cancer, and about 60% of patients have this manifestation. This early symptom of kidney cancer is very deceptive, and many patients or their family members are paralyzed and careless because they see that the patient is not in pain and sometimes good and bad, and as a result, it is delayed until the later stage cannot be treated and regrets it later.

Early manifestations of kidney cancer (2) The lump is a hard, uneven lump in the waist or abdomen, indicating that the kidney tumor has a large volume, and some 1 3-year-old children may also have a kidney embryo mass, which is often found by careful mothers.

Early manifestations of kidney cancer (3) Pain - Kidney cancer patients often feel abdominal pain or dull pain: renal colic occurs only when renal tumor causes hydronephrosis or hematuria: renal embryoma generally does not cause pain.

Early manifestations of kidney cancer (4) Systemic poisoning symptoms 1--Some patients first show systemic toxicity symptoms, such as emaciation, anemia, weakness, etc. 10% to 20% of patients have varying degrees.

Early manifestations of kidney cancer (5) Metastases are like bone metastases, causing bone analysis: spinal metastases, which can cause low back pain and paralysis of the lower limbs: if there are lung metastases, cough, hemoptysis, etc. will occur.

Kidney cancer is a malignant tumor that occurs in the renal parenchyma, and most of them are clear cell carcinomas. Renal pelvic carcinoma is a malignant tumor that occurs in the renal pelvis, and most of them are metastatic epithelial carcinomas. The location of the two occurrences is different. As shown in Fig

Renal pelvic cancer originates from the urothelium and is close to the histological manifestations of bladder cancer, and is prone to invasion of surrounding tissues through lymphatic vessels and invasive growth, or regional lymph node metastasis.

At present, the first-line method is mainly surgery, and chemotherapy is recommended after surgery. There is evidence that immunity also has a certain effect, kidney cancer specifically refers to malignant tumors that occur in organs such as the distal convoluted tubule or proximal convoluted tubule of the kidney, and the possibility of lymph node metastasis is relatively small, and it is easy to metastasize to solid organs such as liver, lung, and intracranial in the late stage In addition to surgical resection, targeted ** or immunity** is required.

At present, it is believed that carcinogenic factors are roughly divided into three categories: physical carcinogenic factors, chemical carcinogenic factors, and viral carcinogenic factors.

Physical carcinogenic factors mainly refer to radiation, such as ultraviolet rays, X-rays, etc., chemical carcinogenic factors such as aflatoxins, nitrites, etc., and thousands of inorganic compounds such as asbestos, chromide, etc. (Smoking is one of the main ways for the human body to ingest chemical carcinogens) Viral carcinogenic agents (such as hepatitis B virus, tumor oncogenic virus, etc. more than 150 kinds) are viruses that can only make cells cancerous. Oncogenic viruses can cause cells to become cancerous mainly because they contain viral oncogenes and the nucleic acid sequences associated with them.

They induce human cells to become cancerous by infecting their genomes and integrating their genomes into the human genome. (e.g. Rous sarcoma virus, etc.).

Hello! Kidney cancer can be caused by the following factors, friends need to pay attention:

1) Genetic factors. Genetic factors are one of the causes of kidney cancer, and there are some families with kidney cancer that are found during chromosomal testing.

2) Obesity and high blood pressure. What causes kidney cancer? Studies have shown that obesity and hypertension are also important causes of kidney cancer: high body mass index (BMI) and hypertension are two independent factors associated with an increased risk of kidney cancer in men.

3) Long-term smoking. Causes of kidney cancer also include long-term smoking. A large number of observational studies have shown that smoking is positively correlated with the incidence of kidney cancer, and the probability of developing kidney cancer is much higher in smokers than in non-smokers.

4) Occupational factors. What causes kidney cancer? The incidence of kidney cancer is also related to occupation, and some studies have pointed out that newspaper printing workers, coke workers, dry cleaning and petrochemical workers have a higher risk of kidney cancer and death.

5) Food and drug factors. Experts say food and drugs may also be the cause of kidney cancer. For example, high intake of dairy products, animal protein, fat, and low intake of fruits and vegetables are risk factors for kidney cancer. Pharmacological diuretics may also be a factor in the development of kidney cancer.

1. Occupation: It has been reported that the risk of kidney cancer and death increases among workers who come into contact with metal shops, newspaper printing workers, coke workers, dry cleaning workers, and petrochemical product workers.

2. Radiation: According to statistics, 26 of the 124 tumors caused by the use of a weak particle radiation source were confined to the kidney, but there were no reports of radiation exposure from radiologists and atomic bomb victims.

3. Smoking: Smoking is positively correlated with the incidence of kidney cancer, and the relative risk factor (RR) of kidney cancer in smokers = 2, and people who have smoked cigarettes for more than 30 years and smoked cigarettes without filters have an increased risk of kidney cancer.

The incidence of kidney cancer is mainly related to smoking, obesity, high blood pressure, radiation hazards, diet, genetics, etc., so the prevention of kidney cancer is mainly carried out in life. Pay attention to the reasonable nutrition in the diet, and for the reasonable combination of protein and vitamins, we should also reduce the intake of many foods containing carcinogens.

It can be said that kidney cancer is more complicated, but smoking is a common one. Smoking produces toxins that induce genetic mutations in the cells of the kidneys and bladder that change from a normal cell to a cancer cell. People who smoke more cigarettes have a higher chance of developing kidney cancer, and those who are willing to chew tobacco have a higher chance of developing kidney cancer.

It has been noted that kidney cancer mainly occurs in the elderly, so the occurrence of liver cancer has a relatively large relationship with age.

The incidence of kidney cancer is unknown, but some data show that its incidence is related to smoking, antipyretic and analgesic drugs, hormones, viruses, radiation, coffee, cadmium, thorium, etc.;

Cancer is very complex, the vast majority of which are unknown, kidney cancer is unknown, there is a family history, smoking, alcoholism, high blood pressure, etc. are high-risk factors

Radiation causes, smoking, occupational causes, genetics, and poor lifestyle habits.

Workers in these occupations such as oil, leather, asbestos and other industries have a high rate of illness.

1. The typical three symptoms of kidney cancer are hematuria, pain and lumps, if these three symptoms appear, it means that it has basically reached an advanced stage at this time, and the patient may have lost the best time, and the operation can be relatively difficult to cut clean, so it should be detected early and early. The best surgical methods also include kidney-sparing surgery and ** nephrectomy surgery, which is determined according to the size of the kidney tumor, generally speaking, the tumor is less than four centimeters, we can take kidney-sparing**.

2 Generally speaking, kidney cancer is less than 4 cm, which is generally at an early stage, but it still depends on the individual's situation, such as whether the tumor has spread, whether it has metastasized, and then the malignancy of the tumor cells. Through these specific situations, we can analyze and evaluate the early or late stage, and we cannot simply say that a few centimeters is early.

3. The incidence of kidney cancer is relatively high, and more than 95% of kidney tumors are malignant and less benign in general.

Generally speaking, benign tumors are expansive or exophytic growth, the growth rate is relatively slow, and the boundary is relatively clear, often with envelope, the texture and color of the tumor are close to normal tissues, while malignant tumors are just the opposite.

4. Cancer is one of the common complications of tumors, which refers to cancer cells that occur in blood vessels or lymphatic vessels similar to blood clots, that is, cancer cells aggregate into a clump, invade blood vessels or lymphatic vessels, cause abnormal blood coagulation function, blood dysfunction, abnormal coagulation, and cancer cell aggregation and formation. Generally speaking, the risk of cancer thrombosis is very large, patients with cancer thrombosis are much worse than patients without cancer thrombus, of course, kidney cancer is also a tumor that often occurs cancer thrombus, once cancer thrombus occurs, it means that the operation may be staged later, then its best effect is also relatively poor.

Problem description: My mother felt backache last week, and after the hospital examination, it was found that there was a 6 cm lump in the kidney, the B ultrasound report wrote a substantial mass, and the CT report wrote a benign key front mass, the doctor said that he was lucky to find it early, and yesterday the surgery removed the diseased left kidney, the surface of the tumor was smooth, and the surrounding lymph was not found to be a lesion, but the doctor said that this is a malignant tumor, and I want to consult what kind of tumor needs to be done after surgery**, how long can I live, and what is the probability of **.

I also wish all good people a safe life.

Analysis: Generally, the 5-year survival rate of kidney cancer after nephrectomy is 35%-40%, and the 10-year survival rate is 17%-30%, and the prognosis of kidney cancer is sometimes difficult to estimate, and metastatic lesions can occur 20 years, 30 years or even longer after kidney cancer resection surgery. A combination of immunization** and chemotherapy may be the best approach.
