Cancer is considered one of the leading causes of death in the world. This pathology, which can affect different organs and tissues of the body, develops discreetly without manifesting any specific symptoms. In particular, lung cancer, which is one of the most common, is a silent killer. Zoom on the causes and signs of this disease.

Each year, nearly 900,000 new cases of lung cancer are recorded among men, compared to 330,000 among women worldwide. It is one of the most common types of cancer and the leading cause of death in men.

Lung cancer is a malignant tumor that develops in the cells of this same organ. Also known as bronchopulmonary cancer or bronchial cancer, 80 to 90% of lung cancer is caused by smoking. While it mainly affects men, women are beginning to suffer more and more because of the rising rate of female smoking.

There are two types of lung cancer:

  • Non-small cell lung cancer is the most common type and is easier to detect and treat. This form of lung cancer develops more slowly and has 3 subcategories, including squamous cell carcinoma, adenocarcinoma, and undifferentiated large cell carcinoma.
  • Lung cancer, small cell: it is a form of cancer of the lungs less common (20% of cases), but much more dangerous. Indeed, it is more aggressive and is characterized by a faster multiplication of cancer cells, which can lead to metastases.
