How are the types of lung cancer determined, and how many types of lung cancer are there?

It seems that the tumor grows rapidly, and the pathological type should be clarified as soon as possible in order to formulate the best plan, because there are many types of lung cancer, different types of lung cancer have different methods, and flexible bronchoscopy is a diagnostic method recommended by the international anti-cancer association guidelines for lung cancer, which will not lead to spread, rather than delaying it or doing it as soon as possible, otherwise the best opportunity will be lost.

Rest assured, this is very unlikely. Fiber bronchoscope only needs to take a little tissue out for biopsy to determine the pathological type, because the determination of the pathological type is of great guiding significance to **.

The incidence of lung cancer in China is on the rise, and lung cancer has become the number one killer of cancer in our country. According to the location of the lesion, we divide lung cancer into central lung cancer and peripheral lung cancer. According to the pathological type, it is divided into small cell lung cancer and non-small cell lung cancer, and non-small cell lung cancer includes lung squamous cell carcinoma, lung adenocarcinoma, lung large cell carcinoma, adenosquamous cell carcinoma, squamous cell carcinoma and bronchial carcinoid carcinoid.

According to the size of the lesion, whether there are hilar lymph nodes, mediastinal lymph node metastasis, extrapulmonary metastases, brain metastases, bone metastases, and abdominal metastases, we divide lung cancer into, early lung cancer, intermediate lung cancer and advanced lung cancer, according to the medical division in the hospital, divided into stage I lung cancer, stage II lung cancer, stage III lung cancer and stage IV lung cancer.

Does not accelerate its spread. Determine the type before medication**.

The types of lung cancer can be divided into ** type (hilar type), peripheral type and diffuse type according to the location of the tumor in the lung.

According to the histological type, it can be divided into: squamous cell carcinoma (80%-85% is ** type), adenocarcinoma (65% is peripheral type), adenosquamous cell carcinoma, small cell carcinoma (mostly ** type), large cell carcinoma (mostly ** type) and sarcomatoid carcinoma.

Type ** refers to a mass that occurs in the main bronchus or lobe bronchi and forms a mass in the hilum region.

The peripheral form originates in the lung segment or its distal bronchi, forming a solitary nodular or spherical carcinous nodule around the periphery of the lung near the lung membrane.

The diffuse type originates from peripheral lung tissue, and grows diffusely along the alveolar ducts and alveoli, forming most miliary nodules covering part or whole lobes of the lobule; Multiple nodules of varying sizes can also form that are scattered throughout multiple lobes.

Small cell carcinoma, also known as small cell neuroendocrine carcinoma, is the most malignant type of lung cancer, and neurosecretory granules can be seen in the cytoplasm of its cells under electron microscopy. This type of lung cancer grows rapidly, metastasizes early, and most of them have a survival time of less than 1 year. Surgical resection is poor, but sensitive to chemoradiotherapy.

Therefore, when the whole must be integrated, the major hospitals in China surgical resection, radiotherapy and chemotherapy and other methods are simple**lungs. People are a whole, must be through 15 meridians massage to dredge the meridians and stasis, Chinese medicine bath legs and feet to regulate the function of the viscera, combined with Chinese medicine enema to smooth the large intestine, severe patients need to cooperate with nutritional support, psychological ** to regulate the body and mind, the whole body scraping sha to remove stasis and circulation, paste and rub medicine to dredge local qi and blood, from these seven aspects of comprehensive**.

Lung cancer is divided into small cell lung cancer and non-small cell lung cancer, with small cell lung cancer accounting for about 20% of the total number of lung cancers, and non-small cell lung cancer including squamous cell carcinoma, adenocarcinoma and large cell carcinoma. If the patient is diagnosed with small cell lung cancer, the patient can receive chemotherapy and radiotherapy, which has a good ** effect; If it is adenocarcinoma in non-small cell lung cancer, patients can do genetic testing such as gene mutations, which is targeted and has a good effect.

Generally, the four types of lung cancer are divided into two categories: 1) small cell lung cancer, which arises from the endocrine cells of the lungs; 2) Non-small cell lung cancer, i.e. all other types. These include: squamous cell carcinoma, which arises from large airway epithelial cells; Adenocarcinoma (including large cell carcinoma), which arises in the secretory area of the lungs; Bronchoalveolar carcinoma, which arises from the small balloon epithelium or alveolar epithelium.

In this . are all in detail.

Lung cancer is classified into small cell lung cancer and non-small cell lung cancer according to histopathological classification.

Small cell lung cancer accounts for about 15% of the total incidence of lung cancer, is the most malignant type of lung cancer, small cell lung cancer proliferates rapidly, and extensive metastasis can occur in the early stage, most patients have systemic metastasis when they are found, and the efficacy of surgical resection is poor, but it is more sensitive to chemotherapy and radiotherapy.

Second, non-small cell lung cancer is mainly divided into squamous cell carcinoma, adenocarcinoma and large cell carcinoma. Patients with squamous cell carcinoma are generally middle-aged and elderly men, most of them have a history of smoking, the tumor generally grows relatively slowly, metastasizes late, and has more opportunities for surgery, adenocarcinoma is the most common type of lung cancer, adenocarcinoma metastasizes through the blood occurs relatively early, large cell carcinoma has a high degree of malignancy, but metastases small cell carcinoma late.

The main clinical manifestations of lung cancer are hemoptysis, cough, sputum production, chest tightness, chest pain, and dyspnea.

On imaging, it appears as a lung mass, atelectasis, or a shadow in the form of pneumonia.

Lung cancer is classified in the following ways: early, intermediate, and advanced.

The clinical staging of lung cancer is divided into stage I, stage, stage and stage according to the stage of the International Union Against Cancer.

From a pathological point of view, it can be divided into adenocarcinoma and squamous cell carcinoma.

Combined pathological and clinical, it can be divided into non-small cell lung cancer and small cell lung cancer.

If there is no metastasis of mediastinal lymph nodes, it should be an early-stage tumor; Metastases to mediastinal lymph nodes, or distant viscera, should be in the middle and late stages.

What are the different types of lung cancer?

Lung cancer can be divided into peripheral lung cancer and type ** lung cancer according to the location of its tumor. Peripheral lung cancer refers to lung cancer below the bronchial segment, while lung cancer above the segment is called ** lung cancer. According to the histopathological cell type, it is divided into small cell lung cancer and non-small cell lung cancer.

Non-small cell lung cancer can be further divided into large cell carcinoma, squamous cell carcinoma and adenocarcinoma. Among them, small cell lung cancer has a poor prognosis. According to the stage of the tumor, it can be divided into early-stage lung cancer, intermediate lung cancer and advanced lung cancer.

Depending on the type of lung cancer, the severity of the patient's condition is assessed, and guidance**.

There are four types of lung cancer, squamous cell carcinoma: this type of lung cancer is the most prevalent, accounting for almost half of all lung cancer patients. Undifferentiated carcinoma:

The incidence of this type of lung cancer is higher in men than in women, and the age of onset is younger. Adenocarcinoma: This type of lung cancer has a relatively low incidence.

Alveolar cell carcinoma: This is the least common type of lung cancer.
