What is Well-differentiated Fetal Adenocarcinoma (Lung)?Well-differentiated Fetal Adenocarcinoma (Lung) is a rare lung tumour having tumour glands and tubules. Well-differentiated lung adenocarcinoma mimics fetal lung at 3-4 months of pregnancy.
Disease Etiology (Causes)There is no definite well-known cause. However, certain genetic mutations (alteration or deletion in normal genes or chromosomes) and long-term cigarette smoking, prolonged exposure to silica dust, asbestos, radon gas, and other chemicals are potential risk factors for the development of adenocarcinoma lung.
Disease EpidemiologyIt is a subtype of adenocarcinoma (lung cancer) of the lung. It accounts for 0.1-0.5% of all lung cancer cases. It is slightly more prevalent in older men who smoke for a long time.
