Types of lung cancer and what are the classifications of lung cancer?

If the physical condition allows, it is best to have surgery, radiotherapy, drugs, etc., which can only be temporarily relieved and delay the development time.

Non-small cell lung cancer and small cell lung cancer, peripheral lung cancer and central lung cancer.

Lung cancer can be divided into two main categories: non-small cell lung cancer and small cell lung cancer. It has been clinically proven that these two types of lung cancer grow and spread differently, and the methods are also significantly different, and the prognosis is also different.

Small cell lung cancer: Also known as oat cell carcinoma, it accounts for about 20% of lung cancers. This type of lung cancer grows rapidly and easily spreads to other parts of the body.

The causes of small cell lung cancer are inextricably linked to smoking. Small cell lung cancer is mainly based on chemotherapy and radiation. Non-small cell lung cancer:

About 80% of lung cancer patients have non-small cell lung cancer. This type of cancer grows and spreads more slowly than small cell lung cancer. There are three types of non-small cell lung cancer:

Squamous cell carcinoma, adenocarcinoma, and large cell lung cancer, which differ in cell types. Most non-small cell lung cancers are related to smoking, but the cause of a few adenocarcinoma and many cases of large cell lung cancer is unknown. Early-stage non-small cell lung cancer (NSCLC) is characterized by surgery, chemotherapy and radiation.

Patients with advanced disease mainly receive chemotherapy and radiotherapy combined with biological immunity. Up to now, there are two types of lung cancer, and lung cancer patients must be diagnosed with which type they are, so as to be better.

There are two main categories of lung cancer:

1) Small cell lung cancer: endocrine cells that arise from the lungs;

2) Non-small cell lung cancer: including 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.

Gamma Knife is suitable for those who can't be operated on and patients who can't bear chemotherapy, you can choose Gamma Knife**, which is relatively better!

Generally, the effect is ideal for those with a diameter of less than 2cm, but it cannot be thorough for relatively large lesions.

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.

Lung cancer can be divided into primary lung cancer and secondary lung cancer. If lung cancer is classified according to pathology, it can be divided into small cell lung cancer and non-small cell lung cancer, while non-small cell lung cancer includes adenocarcinoma, phosphate cancer, undifferentiated lung cancer, large cell carcinoma, etc. According to the location of lung cancer, it can be divided into ** type lung cancer and peripheral lung cancer.

1. Small cell lung cancer: small cell lung cancer (SCLC) or oat cell carcinoma, nearly 20% of lung cancer patients belong to this type; Small cell lung cancer (SCLC) has a short doubling time and rapid progression, often accompanied by endocrine abnormalities or carcinoid syndrome; Because patients have hematogenous metastasis in the early stage and are sensitive to chemoradiotherapy, systemic chemotherapy should be the main treatment of small cell lung cancer, combined with radiotherapy and surgery. The key to success in comprehensive lineage small cell lung cancer.

2. Non-small cell lung cancer: Non-small cell lung cancer (NSCLC) class, about 80% of lung cancer patients belong to this type. This distinction is quite important because the regimens for these two types of lung cancer are very different.

Chemistry is the main treatment for small cell lung cancer patients, and surgery does not play a major role in this type of lung cancer patients. On the other hand, surgery** is mainly for patients with non-small cell lung cancer.

Clinical types of lung cancer.

1. Squamous cell carcinoma (also known as squamous cell carcinoma): It is the most common among various types of lung cancer, accounting for about 50%. Most of the patients are over 50 years old, and most men are affected.

Most of them originate from the larger bronchial tubes and are often type ** lung cancer. Although the degree of differentiation of squamous cell carcinoma varies, the growth and development rate is relatively slow and the course of the disease is longer. Sensitive to radiation and chemistry**.

Lymphatic metastasis occurs first, and hematogenous metastases occur later.

2. Undifferentiated carcinoma: the incidence is second only to squamous cell carcinoma, more common in men, the age of onset is younger, and generally originates from the larger bronchi. According to the morphology of tissue cells, type ** lung cancer can be divided into several types, such as oat cells, small round cells and large cells, among which oat cells are the most common.

Undifferentiated carcinoma has a high degree of malignancy, rapid growth, and extensive lymphatic and hematogenous metastasis occurs earlier, is more sensitive to radiation and chemistry**, and has the worst prognosis among all types of lung cancer.

3. Adenocarcinoma: originates from the bronchial mucosal epithelium, and a few mucus glands originate from the large bronchi. The incidence is lower than that of squamous cell carcinoma and undifferentiated carcinoma, and the age of onset is younger, and it is relatively more common in women.

Most adenocarcinomas originate in the smaller bronchial tubes and are peripheral lung cancers. There are usually no obvious clinical symptoms in the early stages, and they are often detected on chest x-ray. Presents as a round or oval mass that usually grows slowly, but sometimes hematogenous metastases occur early.

Lymphatic metastases occur later.

4. Alveolar cell carcinoma: originates from the bronchial mucosal epithelium, also known as bronchiolar alveolar cell carcinoma or bronchiolar adenocarcinoma. It is located around the lung field, and the incidence rate of all types of lung cancer is the lowest, and it is more common in women.

In general, the degree of differentiation is higher and the growth is slower. Cancer cells grow along the bronchiolar alveolar ducts and alveolar walls without violating the alveolar septum. Lymphatic and hematogenous metastases occur late but may spread through the bronchial tubes to other lobes or invade the pleura.

Alveolar cell carcinoma has two morphological types: nodular and diffuse. The former can be a single nodule or multiple nodules; The latter morphology resembles a pneumonic lesion. For the nodular type with limited scope, surgical resection is effective.

In life, many elderly people suffer from lung diseases, and in severe cases, they will become cancerous and produce lung cancer.

This is a terrible malignant disease, and once it is detected at an advanced stage, it is very difficult to **. Since there are many types of lung cancer, some people don't fully understand them, so let me introduce you to these classifications.

It is most common in bronchial adenomas. Originates from silverophiles in the bronchial mucosa that contain neurosecretory granules. 90% of them occur in large bronchial tubes, which is a ** type tumor.

10% occur in small bronchial peripheral tumors. Lung cancer is the most common primary malignant tumor of the lung, and the vast majority of lung cancers originate from the bronchial mucosal epithelium, so it is also called bronchial lung cancer.

1. Bronchial carcinoid.

Carcinoid organisms grow under the bronchial mucosa, and when they protrude into the bronchial lumen, they form a polypoid mass with a smooth surface and abundant blood vessels, which is easy to bleed. In some cases, the tumor grows inside and outside the bronchial wall at the same time, forming a mass in the bronchial lumen and lungs, which is dumbbell-shaped. The cancer cells are small, morphologically similar, and are lined up in flakes.

Sometimes pseudoacinar is formed, the nucleus is small, the staining is deep, the cytoplasm is eosinophilic, and contains neurosecretory granules.

2. Bronchial cystic adenocarcinoma.

Also known as cylindrical adenoma, it is less common in bronchial adenoma. Originates from glandular ducts or bronchial mucosal secretory glands. Most occur in the lower trachea or proximal bronchi.

It is highly malignant and often erodes the trachea or bronchial wall and its surrounding tissues, causing obstruction of the bronchial lumen, and there may be lymph nodes or distant metastases. Tumor cells are in a sieve-like row, interwoven into columns, ** forming voids and containing eosinophilic substances.

3. Mucoepithelioid carcinoma is the least common in preparative bronchial adenoma. Originating from the bronchial mucosal secretory glands of the lobes, they are often polyp-like, with an intact superficial mucosa and secretion of mucus. Microscopic tumors consist of a mixture of squamous epithelial cells and mucus-secreting columnar cells.

Malignancy is generally low but can erode adjacent tissues.

It is divided into four main categories. Small cell lung cancer, large cell lung cancer, squamous cell carcinoma, adenocarcinoma,

Facing the reality, accepting the reality, positively**, finding a good doctor and a good method, you can be effective**If there is a condition, it is best to combine traditional Chinese and Western medicine**, which can complement each other's advantages, complement each other, treat the symptoms and root causes together, and have a better effect. Therefore, it is also necessary to establish confidence in defeating cancer. Let's face it and believe that you can beat the disease.

Lung cancer can be divided into two main categories: non-small cell lung cancer and small cell lung cancer.

Smoking and environmental factors lead to blockage of meridians, malignant changes in the physique, no matter how good the medicine is, cancer is a local manifestation of systemic diseases, Western medicine**: headache doctor, foot pain doctor, Chinese medicine can carry out systemic conditioning, improve the body's immunity; Prevent the growth of cancer cells; Kills cancer cells; J meridian tumor elimination can dredge the meridians, change the physique, the body qi and blood are sufficient, the meridians are smooth, and many diseases will naturally disappear. It is important for patients to strengthen exercise, improve their own immunity, maintain an optimistic attitude, and face the disease positively.

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.

According to the pathological classification criteria of the World Health Organization, the histological classification of lung cancer can be divided into squamous cell carcinoma, small cell carcinoma, adenocarcinoma, large cell carcinoma, adenosquamous cell carcinoma, sarcomatoid carcinoma, carcinoid carcinoma, salivary gland carcinoma and unclassified carcinoma. The clinical classification of lung cancer can be divided into non-small cell lung cancer (including squamous cell carcinoma, adenocarcinoma, adenosquamous cell carcinoma, large cell carcinoma and sarcomatoid carcinoma, etc.) and small cell lung cancer (including compound small cell carcinoma). You can take a look at (Liu also persevered in the journey of cancer) to understand.

Lung cancer is one of the malignant tumors with the fastest growth rate and mortality rate, and the greatest threat to the health and life of the population. It can be divided into: squamous cell carcinoma, solid tumors are larger, and metastasis occurs later.

Adenocarcinoma is usually asymptomatic in its early stages, so it is easy to ignore. Large cell carcinoma, a solid tumor that grows rapidly and is prone to metastasis, is a common metastasis in the brain, and the prognosis is also poor.

Lung cancer is divided into three types: early, middle and late, lung cancer can be effectively removed by surgery in the early stage, which is conducive to preventing the spread and metastasis of the disease. Fuda recommends that you seek medical treatment nearby to avoid delaying your condition.

Lung cancer is classified as small cell lung cancer and non-small cell lung cancer. The latter include squamous cell carcinoma, adenocarcinoma, large cell lung cancer, mixed cancer, etc. If the examination finds that there are lung shadows, and there are symptoms such as weight loss, chest pain, cough, etc., it is necessary to diagnose lung cancer in time, lung cancer is not terrible, pay attention to diet and rest in life, and simple exercise to improve body resistance.

Things are man-made, and people will overcome the disease, and this is also the truth that we have realized in (Liu Ye's journey). Know how to take care of yourself better.

According to the location of the tumor and the macroscopic morphology, the classification of lung cancer is as follows: 1**, the tumor occurs in the bronchi above the segment, that is, in the lobe bronchi and segmental bronchi.

2.In the peripheral type, the tumor occurs in the bronchi below the segment. 3.

In the diffuse form, the tumour occurs in the bronchioles or alveoli and diffusely in both lungs.

Hello; The routine of lung cancer is as follows: 1. Surgery**: It is still the preferred method for many lung cancer patients.

2. Radiation**: It is not of much help to patients who are not suitable for resection, and the reason is that they cannot be anatomically positioned. Radiation** relieves symptoms of cardia obstruction and relieves chronic bleeding from unresectable lesions.

3. Chemistry**: advanced lung cancer, surgery combined with chemotherapy; Postoperatively** Immunochemotherapy is indicated. 4. Immunization**.

Lung cancer is divided into, small cell carcinoma, non-small cell carcinoma, squamous cell carcinoma, adenocarcinoma.

Liu is also very strong "Perseverance Liu Yi" Therefore, it is also necessary to establish confidence in defeating cancer. Let's face it and believe that you can beat the disease.

Squamous cell carcinoma, adenocarcinoma, etc.
