Where does lung cancer metastasize first? What are the main routes of lung cancer metastasis?

1.Mediastinal lymph gland metastases and manifestations of superior vena cava syndrome.

Mediastinal lymph gland metastasis in lung cancer is manifested by recurrent laryngeal nerve palsy and hoarseness. Symptoms of superior vena cava syndrome include edema of the face, neck, and upper extremities.

2. Manifestations of spinal cord metastasis and liver metastasis.

The common symptoms of spinal cord metastasis of lung cancer are urinary retention, paraplegia and paraplegia. Symptoms of lung cancer patients, lung cancer liver metastasis symptoms are liver pain, jaundice, ascites and other digestive symptoms, patients will have unexplained weight loss, liver regional pain and body surface jaundice, B ultrasound liver enlargement, medium or hard, irregular edge shape, surface unequal.

3. Manifestations of brain metastases and bone metastases.

Most of the symptoms of lung cancer after surgery occur within 1 to 2 years after surgery, and lung cancer patients will have unexplained headaches, vomiting, visual impairment, personality and spleen changes, most of which are caused by intracranial hypertension or cranial nerve damage caused by lung cancer metastasis to the brain. Headache is the most common symptom of lung cancer patients**, and bone metastasis of lung cancer is manifested by local bone tenderness, impaired mobility, and pathological fractures.

Hello, the common metastasis sites of lung cancer include intrapulmonary metastasis, mediastinal lymph node metastasis, bone metastasis, liver metastasis, brain metastasis, etc., you can consult me for details.

I'm a doctor. QQ Consulting.

Liver metastasis, bone metastasis, and lymphatic metastasis are the most common, and the first is lymphatic metastasis, and the metastasis routes include lymphatic metastasis, implant metastasis, hematogenous metastasis, etc.

First to the hilar lymph nodes, then to the paratracheal lymph nodes, then to the subclavian and superior lymph nodes, as well as bone, brain, and liver metastases.

a.Localized spread.

b.Exfoliated cell seeding.

c.Slag spring migration before lymphatic transfer.

d.Hematogenous metastases.

e.Directly vine wisdom and extension.

Will lung cancer metastasize to ** first? Lung cancer is easy to metastasize, and several sites that are easy to metastasize at work are adrenal glands, brain, liver, bones, lymph node metastases, and so on. Speaking of the earliest site of metastasis, the situation of metastasis is different for each person, some people have brain metastases first, some people have adrenal metastases first, and some people directly have bone metastases.

Most of the lung cancers found with symptoms are in the middle and advanced stagesAt present, most of the lung cancers encountered in clinical practice are seen with symptoms such as cough, sputum, hemoptysis, and chest pain, which is a pity. Most of them are already in the middle and late stages.

Some of them do not have symptoms in the lungs, but have symptoms at the site of metastasis. For example, a ** written two days ago, a 56-year-old woman, dizziness and headache for a month. Headache, many people don't care, a month later, I really can't do it, I did a CT, I found that there was something in the brain, and there was a lot of edema around, seeing such a performance, I must think of the possibility of metastasis, then the most common is the brain metastasis of lung cancer, sure enough, I did a chest CT, and found that there is indeed a lesion in the lung, and the signs of malignancy are obvious.

Considering lung cancer with brain metastases, it is basically fine. However, the final diagnosis still depends on pathology.

There are also patients with low back pain, who have low back pain for a while, thinking that they are tired from work, and they don't care, but the pain is getting worse and worse. I did an X-ray of the lumbar spine, slight bone damage, X-ray may not be visible, it is best to do CT, CT found that the bones of the lumbar spine were destroyed and some were eaten, and the possibility of metastasis should be suspected first, the first thing to think of lung cancer is to do chest CT to take a look.

Lung cancer is also prone to metastasis of the adrenal glands. The probable mechanism is hematogenous metastasis. Therefore, many people who suspect lung cancer and need surgery routinely do adrenal gland scans to see if there are metastatic lesions in the adrenal glands.

There is also the occurrence of metastases in the lungs themselves.

The metastasis of lung cancer to other organs is not in a certain order, and everyone will be different, and the most terrible thing about cancer is its ease of metastasis. Lung cancer is the most common cancer, and the risk of metastasis is also high. Among lung cancers, there is small cell lung cancer, which is prone to lymph node metastasis at an early stage.

Lung adenocarcinoma is prone to metastasis of the brain, liver, bones, adrenal glands, lymph nodes and abdominal cavity, and there is no prescribed order for its metastasis, and everyone may be different, so it may not be the earliest metastasis.

First it will be transferred to the brain, and then to the bones; Liver; Among these organs, it is necessary to pay attention to them in daily life. And. Eat foods that are high in protein and low in sugar. Don't eat sweets in your daily life.

Hello, the ways of lung cancer spread and metastasis can generally be summarized into four types: local invasion, blood tract metastasis, lymphatic tract metastasis and implant metastasis. Local invasion is when a tumour invades adjacent organs or tissues. The main sites of bloodstream metastases are the liver, bones, brain, adrenal glands, and the lungs themselves.

Lymphatic metastasis is an important pathway for lung cancer metastasis, especially small cell undifferentiated carcinoma.

Lung cancer can metastasize to multiple sites in the early stage, the most common is lymph node metastasis, liver metastases, brain metastases, bone metastases, etc. may occur.

Local invasion is when a tumour invades adjacent organs or tissues. The main sites of bloodstream metastases are the liver, bones, brain, adrenal glands, and the lungs themselves.

Lymphatic metastasis is an important pathway for lung cancer metastasis, especially small cell undifferentiated carcinoma, which can occur early. Implant metastasis is when the tumor is directly implanted somewhere to grow and form a new lesion, which can occur at any site.

In the advanced stage of lung cancer, metastasis of various organs can occur, which can cause corresponding symptoms, often bring great pain to patients, and even threaten life.

The most common clinical metastases are the following sites:

Brain metastases from lung cancer.

Unexplained headache, vomiting, visual disturbances, personality and spleen changes in lung cancer patients may be caused by intracranial hypertension or cranial nerve damage caused by lung cancer metastasizing to the brain.

Bone metastases from lung cancer.

About 50% of lung cancer patients eventually develop bone metastases from multiple sites.

Liver metastases from lung cancer.

The liver is also a common site of metastasis of lung cancer, with liver metastases occurring in about 28-33% of lung cancers.

Kidney and adrenal metastases from lung cancer.

Kidney and adrenal glands are the result of hematogen metastasis in the advanced stage of lung cancer, and about 17%-20% of lung cancer patients have kidney and adrenal metastases.

Metastasis of lung cancer to other sites.

In addition to the above-mentioned common metastatic sites, the less common metastatic sites of lung cancer include metastasis of subcutaneous tissue, muscle, intra-abdominal cavity, heart and other parts, and the symptoms are often related to the metastatic site.
