LUNG CANCER LEARN MORE ...

  • Lung cancer is a process caused by the uncontrolled growth of abnormal cells in the lung

    Normally, cells grow and divide to form new cells that will replace those that have aged and died. While these new normal cells differentiate to occupy a place and function to maintain life, the tumor cells grow and multiply in a disordered way, giving rise to a tumor

    Malignant tumors or cancers are characterized by their ability to invade other parts of the body. In lung cancer abnormal growth is initially pulmonary, but is able to invade and damage the surrounding organs and tissues. Later on the tumor can invade blood vessels and lymph vessels, allowing tumour cells to enter the blood and lymph system and reach other organs and tissues (lymph nodes, liver, bones, brain,…) where new tumours will form (metastases).

    Like all organs in our body, the lungs are made up of many types of cells, giving rise to different lung cancers. Lung cancer comprises two major types: non-small cell lung cancer (NSCLC), with two main subtypes: adenocarcinoma, the most common (60%) and squamous cell carcinoma (25-30%), and small cell lung carcer (SCLC). These two types of lung carcinoma have a very different evolution, treatment and prognosis.
