What are the symptoms of kidney cancer? Symptoms and causes of kidney cancer

Depending on the stage, kidney cancer may have different symptoms. The specific symptoms are as follows:

1. Early kidney cancer: generally no special symptoms, mainly found through physical examination, including normal physical examination and other disease examinations, is the main way to detect kidney cancer early;

2. Intermediate and advanced kidney cancer: If the tumor progresses to a certain extent, such as invading the renal pelvis, hematuria may occur, which is mainly manifested as gross hematuria regurgitation. If the tumour is large, a swollen mass can be felt in the abdomen, and if the tumour ruptures and bleeds in a short period of time, it may cause severe pain in the abdomen.

Once the above symptoms appear, it generally indicates a late stage of kidney cancer;

3. Advanced kidney cancer: After the tumor metastasizes, there will be corresponding metastatic symptoms, such as cough, hemoptysis and lung inflammation may occur when lung metastases occur. If it metastasizes to the bone, it can cause bone pain and fractures.

If it metastasizes to the brain, a range of symptoms in the brain may occur.

Kidney cancer is best prevented, not **, so what are the symptoms and causes of kidney cancer?

The occurrence of kidney cancer is related to the patient's bad lifestyle habits, for example, the patient smokes a lot, and knows that smoking is harmful to health, and most diseases are related to smoking, and kidney cancer is not excluded. Studies have found that people who have smoked cigarettes for more than 30 years and smoked unfiltered cigarettes have a high risk of kidney cancer. Diet is also a common factor that leads to the occurrence of diseases, if you consume high levels of dairy products, animal protein, and fat for a long time, and consume too little fruits and vegetables, it is easy to lead to the occurrence of kidney cancer, and coffee may increase the risk of kidney cancer.

Usually, there is no pain or discomfort in the early stage of kidney cancer, and the pain caused by kidney cancer itself accounts for only about 40% of patients. In the advanced stage of the lesion, it can cause soreness and pain in the lower back due to the tumor mass compressing the renal capsule or stretching the renal pedicle, and occasionally colic due to blood clot obstruction of the ureter when the bleeding is severe.

1. Low back pain: The enlargement of the tumor will cause the renal capsule to compress the peripheral nerves and intramuscular tissues, and generally feel dull pain in the lower back or upper abdomen, and there will also be colic, which is due to the blockage of the blood clot when it is discharged through the ureter. You must pay attention to the fact that it is easy to be confused with kidney or ureteral stones at this time, and it is important not to delay treatment due to misdiagnosis.

2. Hematuria: mostly sudden gross hematuria, not accompanied by pain or any uncomfortable symptoms, often intermittent attacks, often unnoticed because of self-stopping, and only go to the hospital for examination when it is reversed. At this time, it means that it is no longer an early stage of kidney cancer.

Here's a reminder that we should pay attention to hematuria, and once hematuria occurs, seek medical attention as soon as possible, the effect will be better.

3. Lumbar mass: When the tumor tissue grows to a considerable size, the patient takes the lateral decubitus position, and the lump can be felt in the waist or upper abdomen. If the lumbar lump and surrounding tissues are adhesive, fixed, or difficult to push, it is more likely to be advanced.

The above is the introduction made by Beijing Deshengmen experts for you, if you don't understand something, you can call the expert**, and the expert will ask you to give a detailed answer.

Hello, the common symptoms of kidney cancer mainly include low back pain, lumps and hematuria, etc., if you have the above symptoms, it is recommended that you delay the condition in time, and it is also very important when choosing the first method, because kidney cancer is very insensitive to radiotherapy and chemotherapy, and often does not achieve the desired effect.

The main symptoms of advanced kidney cancer are: low back pain, lumbar and epigastric mass, hematuria, spermatic vein, and systemic poisoning symptoms such as weight loss, fever, and decreased immunity.

At the same time, cancer metastasis - liver metastasis, bone metastasis, lung metastasis, etc., will occur in the advanced stage of kidney cancer, resulting in rapid deterioration of the condition, great difficulty, poor effect, and abnormal pain, lack of appetite, lack of energy and other manifestations. Advanced stage of kidney cancer** should be based on the patient's feelings, with the aim of reducing the patient's pain and prolonging the patient's survival. At the same time of Western medicine surgery, radiotherapy and chemotherapy, it can assist Ganoderma lucidum and Grifola D to prevent synergistic separation**, improve the patient's immunity, reduce the patient's discomfort symptoms, improve the patient's quality of life, and prolong his life as much as possible.

1. Kidney cancer patients do not feel pain or discomfort in the early stage, but there is a very prominent early symptom of kidney cancer is hematuria, which has a characteristic, that is, it does not hurt when urinating, that is, the so-called ** hematuria. If there is a lot of bleeding, the urine is red or pale pink.

2. Pain increases. In the early stage, it is often overlooked because patients feel that their low back pain is caused by fatigue and will not be treated with caution. However, it is important to understand that patients with kidney cancer often have a dull or dull pain in the abdomen; Renal colic occurs only when renal pelvic tumors cause hydronephrosis or hematuria; Kidney embryoma is generally not painful.

3. Intermittent blood in the urine of kidney cancer patients, which is one of the early symptoms of kidney cancer. Blood in the urine can be relieved naturally after a few days, or some medicine may be taken to temporarily stop the bleeding, often the patient will ignore the carelessness and do not have a detailed examination in time.

4. Lump in the waist. When the tumor tissue grows to a considerable size, the patient is placed in the lateral decubitus position, and the lump can be felt in the lower back or upper abdomen. If the mass is adherent, fixed, and difficult to push with the surrounding tissues, it is mostly at an advanced stage, because the tumor enlarges and involves the renal capsule to compress the peripheral nerves and intramuscular tissues.

5. The early symptoms of kidney cancer include blood in the urine. That is, the blood in the urine that cannot be seen with the naked eye, and when the microscopic examination in the hospital is found to have erythrocytosis, that is, the microscopic hematuria, there is no reason for hematuria, and the microscopic hematuria that does not improve with general drugs should also be paid attention to.

6. There is a lump. The incidence of kidney cancer is also different for people with different constitutions. Usually people with kidney cancer will gradually form a lump in the waist or abdomen, and these lumps will gradually become hard and uneven.

However, due to the hidden location of the kidneys, it is difficult to detect the lump until the kidney cancer reaches a considerable size.

7. Low back pain is another common symptom of kidney cancer, most of which are dull pain, confined to the lower back, and the pain is often caused by the growth of the lump and the distension of the kidney capsule, and the blood clot can also cause low back pain through the ureter. When the tumor invades the surrounding organs and lumbar muscles, the pain is severe and persistent.

8. Edema and hematuria. Kidney cancer can also be accompanied by secondary left varicocele, edema of the lower limbs can occur when the cancer embolesis invades the inferior vena cava, patients with distant metastases of the lesion can have symptoms of metastatic lesions, and the first gross hematuria is often the initial symptom of the patient's visit.

Hello! Common symptoms of kidney cancer are:

1 Hematuria: Hematuria is often the first intermittent episode of the first sex, and the whole course of hematuria is visible to the naked eye, and the intermittent period shortens with the development of the lesion. Kidney cancer may bleed a lot with renal colic, often caused by blood clots passing through the ureters.

Blood clots in the urine of kidney cancer may form in strips through the ureters. The degree of hematuria is independent of the size of the kidney cancer. Kidney cancer can sometimes present with persistent microscopic hematuria.

In most cases, hematuria is caused by tumor invasion of the renal pelvis or calyce. Hematuria is almost the only symptom in patients with renal pelvic cancer.

2 Low back pain: Low back pain is another common symptom of kidney cancer, most of which are dull pain, confined to the lower back, and the pain is often caused by the growth of the lump and the distension of the kidney capsule, and the blood clot through the ureter can also cause low back pain. When the tumor invades the surrounding organs and lumbar muscles, the pain is severe and persistent.

Blood in hematuria coagulates in the ureters into a cord-like blood clot that is excreted in the urine, causing renal colic.

3 Mass: Lumps are also a common symptom, and about 1 3 1 4 patients with kidney cancer can find enlarged kidneys at presentation. The kidneys are hidden, and it is difficult to detect a lump until the kidney cancer has reached a considerable size.

If the mass is fixed, it indicates infiltrates around the kidneys and the prognosis is poor. In general, a lump in the abdomen is a late symptom.

4 Pain: Pain occurs in about 50 cases, and is also an advanced symptom, which is a persistent pain in the lower back on the affected side caused by the renal capsule or renal pelvis being pulled by a growing tumor, or due to tumor invasion and compression of connective tissues, muscles, lumbar spine or lumbar nerves in the posterior abdominal wall.

Other symptoms: unexplained fever, or metastasis at the time of onset, pulmonary symptoms such as fatigue, weight loss, loss of appetite, anemia, cough, and hemoptysis. In addition, the effects of renal adenocarcinoma are caused by tumor endocrine activity, including polycythemia, hypertension, hypotension, hypercalcemia, and febrile syndrome.

Although these systemic, toxic, and endocrine effects are non-specific, about 30 percent of patients begin with many mixed manifestations. Thus valuable clues, this finding is considered for the systemic role of the tumor.

The typical symptoms of kidney cancer are pain, fatigue and possible urinary tract bleeding.

Kidney cancer patients need to pay attention to their diet during the ** period, but the symptoms should be paid attention to understand, and the early symptoms of kidney cancer are mainly as follows:

1. Pain: Kidney cancer patients often have dull or dull pain in the abdomen; It is a common manifestation in the early stage, and it is generally more obvious in the late stage, and the pain can be relieved on its own in the early stage, and it is not easy to detect. Renal colic occurs only when renal pelvic tumors cause hydronephrosis or hematuria;

2. Systemic symptoms: patients may have fatigue, emaciation, unexplained fever and edema in the early stage; It is also accompanied by a marked loss of appetite: abdominal distension, dyspepsia, and sometimes nausea, vomiting.

3. Other symptoms: In the early stage of kidney cancer, there may be a lump in the waist, and the kidney cancer patient may feel a hard and uneven lump in the waist or abdomen. This indicates that the tumor volume of kidney cancer is already large.

Again, some patients will also have hematuria, which is also a typical symptom of kidney cancer.

4. Hematuria: mostly sudden gross hematuria, sometimes terminal hematuria, the whole process of hematuria is generally not accompanied by painful or uncomfortable symptoms, often intermittent attacks, can stop on its own without being noticed; It is not until the recurrence of the disease that the patient goes to the hospital for examination.

5. Low back pain: The reason is that the tumor is gradually enlarged and involves the renal capsule to compress the peripheral nerves and intramuscular tissues. The pain is mainly in the waist and abdomen, and the pain is manifested as pins and needles and dull pain, and sometimes the blood clot is blocked when the blood clot is discharged through the ureter, and severe colic pain occurs, which is often misdiagnosed as caused by kidney stones, delaying the disease.

6. Lumbar lump: When the tumor cells grow to a certain extent, there will be a lump in the patient's waist or abdomen, which can sometimes be touched by hand, if the lump is adherent, fixed and not easy to push with the surrounding tissues, it is mostly at an advanced stage.

1.Haematuria.

**Sexual intermittent hematuria is a major feature of kidney tumors. ** Indicates that the tumor does not have any pain in the early stage except for hematuria: intermittent indicates that hematuria occurs when the tumor bleeds or invades the renal pelvis, and the hematuria disappears when the bleeding stops.

This early symptom of kidney tumor is very deceptive, and many patients or their family members regret it because they see that the patient is not painful and sometimes good and bad, so they are paralyzed and careless, and the result is delayed until the later stage cannot be treated.

2.Lump A hard, bumpy lump felt in the lower back or abdomen. This indicates that the kidney tumor is already large in size. Some children aged 1 to 3 years may also have a kidney embryonic mass, which is often found by the mother.

3.Pain Patients with kidney cancer often have a dull or dull pain in the abdomen, and renal pelvic tumors present with renal colic only when they cause hydronephrosis or hematuria.1 Renal embryoma generally does not cause pain.

4.Symptoms of systemic poisoningSome patients first present with symptoms of systemic toxicity, such as emaciation, anemia, and weakness. 10% to 20% of patients have fever of varying severity. Low-grade fever is common in renal embryomas.

Hematuria, low back pain, lumps, pain.

The causes of kidney cancer are: 1. Smoking: A large number of data show that smoking is the main cause of kidney cancer. 2. Obesity and hypertension.

3. Occupation. 4. Radiation: This is a factor worth considering in the cause of kidney cancer.

5. Heredity: There are some families of kidney cancer, which are found during chromosomal examination. 6. Food and Medicine:

The survey found that high intake of dairy products, animal protein and fat, and low intake of fruits and vegetables are risk factors for kidney cancer. Misuse of antipyretic analgesics, especially phenacetin-containing drugs, increases the risk of renal cancer. Diuretics may also be a factor in the development of kidney cancer.

The three common clinical manifestations of kidney cancer are hematuria, pain and mass, and intermittent gross hematuria is the common symptom, indicating that the tumor has invaded the calycealis and renal pelvis. The pain is usually dull or dull in the lower back. Renal colic can occur when the blood clot passes through the ureter, usually due to tumor growth pulling the renal capsule or invading the organs adjacent to the psoas muscle.

When the tumor is large, it is easy to be palpable in the abdomen or waist, and most patients have only one or two of the above symptoms, and the appearance of any of the above symptoms is a clinical manifestation of the lesion progressing to an advanced stage.

Local tumor growth can cause a dull ache in the abdomen; When the tumor grows to a certain size, a mass can be palpated in the waist and abdomen, usually the surface of the mass is smooth, the texture is hard, there is no obvious tenderness, and it moves with respiratory movements, if the mass is relatively fixed, it may have invaded adjacent organs or psoas muscles; If the tumor invades the renal pelvis, there will be intermittent, **, gross hematuria. When a bleeding blood clot blocks the ureter, abdominal cramps may occur. With the advancement of imaging technology, more and more kidney cancer patients are being diagnosed with cancer without symptoms.
