There are many types of lung cancer, today let experts from Hefei Phoenix Cancer Hospital tell you about the types of lung cancer, if you want to know, come and have a look. Experts said that more than 96% of lung cancer patients’ development starts from bronchial tube, and according to the different parts of development, it can be divided into two types: central type and peripheral type. One type is central type lung cancer: it develops in the central position of lung. Lung cancer is divided into different kinds according to other classifications. What are the types of lung cancer? Small cell lung cancer, also called oat cell cancer, accounts for about 20% of lung cancer. This type of lung cancer grows rapidly and easily metastasizes to other parts of the body. The cause of small cell lung cancer is closely related to smoking. The treatment of small cell lung cancer is mainly based on chemotherapy, together with radiation therapy. 2. Bronchial Carcinoma Most of the cancers appear in the submucosa of bronchial tubes and protrude into the lumen of bronchial tubes to form polypoid masses with smooth surface and rich blood vessels, which are easy to bleed. In some cases, the tumor grows inside and outside the bronchial wall at the same time, forming lumps in the bronchial cavity and lungs, similar to the shape of dumbbells, which is also one of the lung cancer types. Peripheral lung cancer usually occurs in the periphery of lungs, so it usually does not produce symptoms of cough and hemoptysis. Some patients may have hidden pain, dull pain, or intermittent pain in the chest, but when the tumor increases in size. In order to prevent misdiagnosis, usually patients over forty years old who suddenly find round shadows in the lungs and cannot be diagnosed as tuberculosis, it is better to have timely surgical treatment. 4. Non-small cell lung cancer About 80% of lung cancer patients get non-small cell lung cancer. This kind of cancer grows and spreads slowly compared with small cell lung cancer. There are three types of non-small cell lung cancer: squamous, adenocarcinoma and large cell lung cancer, which have different cell types. The cause of most non-small cell lung cancers is related to smoking, but the cause of a few cases of adenocarcinoma and many cases of large cell lung cancer is unknown. Treatment for early stage non-small cell lung cancer is primarily surgery with chemotherapy and radiation. Patients with advanced stage mainly receive a combination of chemotherapy and radiotherapy. Bronchial cystic adenocarcinoma, also known as cylindrical adenoma, is one of the rare types of lung cancer. It occurs in the glandular ducts or bronchial mucosa secretory glands. Most of them occur in the lower part of the trachea or proximal birth bronchus. The degree of malignancy is high, and it often erodes the wall of the trachea or bronchus and its surrounding tissues, which may lead to the obstruction of the bronchial lumen and gonorrhea nodes or distant metastasis. Tumor cells are arranged like a sieve, interwoven into columns, with gaps in the middle, containing eosinophilic substances. Mucinous epithelioid carcinoma is a rare type of lung cancer. It occurs in bronchial mucosa secretion gland of lung lobe, which looks similar to polyp, with intact surface mucosa and secretion of mucus at the same time. On microscopic examination the tumor consists of a mixture of squamous epithelial cells and mucus-secreting columnar cells. The severity is relatively low, but it has a corrosive effect on nearby tissues.
