Types and Symptoms of Lung Cancer

Share This
According to the World Health Organization (WHO), lung cancer accounts for the highest number of cancer deaths, more than twice as high as colorectal cancer. It continues to rise and this data reminds you that you should pay attention to physical heterogeneity. Early symptoms of lung cancer are cough and shortness of breath, followed by chest pain with additional signs and warnings. There are two main types of lung cancer: Non-small-cell lung carcinoma and Small-cell lung cancer carcinoma and several types of lung cancer by differentiation and morphological characteristics. This article will introduce early signs, ethology, symptoms, cancer types and staging.

Risk factors

The most accessible way to get cancer is smoking, which increases the risk of cancer. Excluding family history, other factors that increase the risk of lung cancer are:

High levels of air pollution

  • Arsenic
  • Radon gas
  • Asbestos
  • Exposure to carcinogenic chemicals such as Uranium, coal-fired products, gasoline or diesel exhaust gases.

What are the potential symptoms of lung cancer?

For smokers, cough is the most neglected sign of lung cancer. If cough persists along with blood, it is a sign of exacerbation. In addition, respiration, shortness of breath and chest pain are often overlooked potential symptoms of lung cancer. In addition to the above, other possible symptoms are: loss of appetite, weight loss, weakness, fatigue, dysphagia, hoarseness of voice, facial paralysis, ptosis of the eyelids, bone pain, etc. Some of these signs are early symptoms. If you have these conditions, please consult a doctor.

Non-small cell lung cancer

Non-small cell lung cancer is the most common type of lung cancer and can be divided into the following three categories:

Squamous-cell Carcinoma

Most of this type of tumor lesions begin near the central bronchus, where cavity is formed in the tumor centre and necrosis.

Adenocarcinoma

Non-smokers often suffer from lung cancer, which is usually long on the margins of the lungs. One type of bronchioloalveolar carcinoma is common in women who have no history of smoking.

Large-cell lung carcinoma

The rapid growth and diffusion of these cancer cells make it very difficult to treat.

Small cell lung cancer

Small cell lung cancer tumors usually appear in larger bronchial areas. The cause of this is very closely related to smoking, and the proportion of such cancers is less likely but the future outlook is not optimistic, as cancer cells are found to have the ability to transfer to other organs.

Cancer metastasis

Metastatic Cancer refers to the spread of cancer from the onset site to the rest of the body. Why is the lung cancer mortality rate so high? One of the reasons for the difficulty of treatment is that there is a chance of metastasis in early cancer. The most common part of lung cancer is Adrenal Glandliver. In addition, the lungs is common metastasis for other cancers.

What does cancer stage mean?

Lung cancer uses TNM (representing tumor Tumor, local lymph nodes Regional Lymph Nodes, and distant metastasis Distant The Metastasis) stoning system is the standard, the higher the number, the larger the tumor.

More common classifications are expressed as periods.

Stage 0: Cancer cells are still in their initial position.
Stage 1: Cancer cells continue to grow but have not spread to nearby tissues.
Stage 2 and 3 (Stage II, III): Cancer cells continue to grow outside the primary site, while spreading and affecting surrounding tissues.
Stage IV: This period means that cancer has spread to other organs or parts of the body, sometimes referred to as “late”.

Always pay attention to the body

Although lung cancer is deadly, you can reduce the risk of cancer by avoiding potential risk factors. The easiest way to quit smoking is to keep abreast of eating, exercise and other healthy habits. and other cancer information. Regular health checks are also key to prevention.
