    en.wikipedia.org/wiki/Radiation-induced_cancer

    Radiation hormesis is the conjecture that a low level of ionizing radiation (i.e., near the level of Earth's natural background radiation) helps "immunize" cells against DNA damage from other causes (such as free radicals or larger doses of ionizing radiation), and decreases the risk of cancer. The theory proposes that such low levels activate ...

    en.wikipedia.org/wiki/Lung_cancer

    Lung cancer, also known as lung carcinoma, is a malignant tumor that begins in the lung. Lung cancer is caused by genetic damage to the DNA of cells in the airways, often caused by cigarette smoking or inhaling damaging chemicals. Damaged airway cells gain the ability to multiply unchecked, causing the growth of a tumor.

    Cancer Radiation is a potential cause of cancer, and secondary malignancies are seen in some patients. Cancer survivors are already more likely than the general population to develop malignancies due to a number of factors including lifestyle choices, genetics, and previous radiation treatment.

    Radiation-induced lung injury (RILI) is a general term for damage to the lungs as a result of exposure to ionizing radiation. [1] In general terms, such damage is divided into early inflammatory damage ( radiation pneumonitis ) and later complications of chronic scarring ( radiation fibrosis ).

    In 2019, the FDA granted accelerated approval to pembrolizumab for people with metastatic small cell lung cancer (SCLC) with disease progression on or after platinum-based chemotherapy and at least one other prior line of therapy. [49] Non-small cell lung cancer (NSCLC) cells expressing programmed death-ligand 1 (PD-L1) could interact with ...

    These tests include lung cancer screening, breast cancer screening, and more. [26] [27] Radiation is also used as therapy for many different types of cancer. [28] About 50% of all cancer patients receive radiation therapy. [28] Radiation therapy destroys cancer cells, stopping them from growing. [28]
