Bronchiolar carcinoma, also known as bronchiolar adenocarcinoma, is a rare type of lung cancer that originates from the bronchioles, which are the smallest airways within the lungs. It is classified as a subtype of adenocarcinoma, a type of non-small cell lung cancer.
Bronchiolar carcinoma usually develops in individuals with a history of smoking or exposure to environmental toxins, although it can also occur in non-smokers. It typically affects adults, with a higher incidence in males.
This cancer starts in the lining of the bronchioles, the tiny air passages that connect the bronchi (the larger airways) to the alveoli (the air sacs in the lungs). The abnormal growth of cells in the bronchioles leads to the formation of tumors, which can spread locally or metastasize to other parts of the body.
Symptoms of bronchiolar carcinoma may include coughing, wheezing, shortness of breath, chest pain, fatigue, weight loss, and coughing up blood. However, these symptoms can be nonspecific and similar to other respiratory diseases, making early diagnosis challenging.
Treatment for bronchiolar carcinoma usually involves a combination of surgery, radiation therapy, and chemotherapy. The specific treatment plan depends on factors such as the stage of cancer, overall health of the patient, and presence of any genetic mutations. Prognosis varies widely and is influenced by various factors, including tumor size, stage of cancer at diagnosis, and the patient’s overall health.
In summary, bronchiolar carcinoma is a rare form of lung cancer that arises in the bronchioles. Early detection and appropriate treatment are essential for improving the prognosis and outcomes for patients with this condition.
