    Frequently Asked QuestionsLung Cancer Stages

    How does lung cancer spread?

    Cancer cells can break away from your initial tumor and travel to your lymph nodes. Once there, cancer cells multiply, forming new tumors. Additionally, cancer cells can leave your initial tumor and travel through your blood to form new tumors.

    Does my lung cancer stage determine my chance of survival?

    Not entirely. Although survival rates are generally grouped based on stage (a.k.a how far your cancer has spread), other factors affect your prognosis such as age, overall health, how well your cancer responds to treatment, and more.

    What is the most common stage to be diagnosed with lung cancer?

    About 80% of people of individuals are diagnosed at stage III or IV lung cancer, which can mean that the disease has already metastasized to other organs beyond the lungs.

    What is stage 0 lung cancer?

    Stage 0 lung cancer is also called lung carcinoma in situ, or pre-cancer. At this stage, lung cancer is present only in the top layer of cells of the bronchi, bronchioles or alveoli without reaching into the layers below.
