Experts briefly analyze the common types of lung cancer

The classification of lung cancer is a matter of great concern to many lung cancer patients and their families, and it has a great impact on the treatment of lung cancer. So what are the common types of lung cancer ? Let's talk about the common types of lung cancer.

In general, the common types of lung cancer are:

1. Squamous cell carcinoma (also known as squamous cell carcinoma)

It is the most common type of lung cancer, accounting for about 50%. Most patients are over 50 years old, and most are men. Most of them originate from larger bronchi and are often central lung cancers. Although the degree of differentiation of squamous cell carcinoma varies, it generally grows and develops slowly and has a long course. It is more sensitive to radiation and chemotherapy. It first metastasizes through the lymph nodes, and blood metastasis occurs later.

2. Undifferentiated carcinoma

The incidence of this type of lung cancer is second only to squamous cell carcinoma. It is more common in men, with a younger age of onset, and generally originates from larger bronchi. Central lung cancer can be divided into several types based on the morphology of tissue cells, such as oat cell, small round cell and large cell, among which oat cell is the most common. Undifferentiated carcinoma is highly malignant, grows fast, and metastasizes to lymph nodes and blood at an early stage. It is more sensitive to radiation and chemotherapy and has the worst prognosis among all types of lung cancer.

3. Adenocarcinoma

Originated from the bronchial mucosal epithelium, a few originate from the mucous glands of large bronchi, and are also a common type of lung cancer. The incidence rate is lower than that of squamous cell carcinoma and undifferentiated carcinoma, the age of onset is younger, and it is relatively more common in women. Most adenocarcinomas originate from smaller bronchi and are peripheral lung cancers. There are generally no obvious clinical symptoms in the early stages, and they are often discovered during chest X-ray examinations. They appear as round or oval masses, which generally grow slowly, but sometimes blood metastasis occurs in the early stages. Lymphatic metastasis occurs later.

The above is an introduction to the common types of lung cancer. I believe everyone has some understanding of this. Once you have lung cancer, you must go to the hospital for treatment in time to avoid missing the best time for treatment.
