An Overview of Lung Cancer

Abstract

Lung cancer is characterised by unregulated cell growth. The most prevalent cancer killer worldwide is lung cancer. Lung cancer diagnoses and deaths are rising worldwide. Males and females over 70 have the highest lung cancer risk. Since 50% of lung cancer patients acquire a new cough, smokers or former smokers should be concerned. Lung cancer's complex pathogenesis is yet unknown. Smoking and carcinogen exposure can cause lung epithelial dysplasia. The most prevalent lung cancer diagnosis methods are flexible bronchoscopy and transthoracic sampling. Immunotherapy helps the immune system recognise and fight cancer cells as foreign intruders. Radiation and four to six chemotherapy cycles are usual for mediastinal or hilar lymph node LS-SCLC.
