All you need to know about: lung adenocarcinoma
Lung adenocarcinoma is a form of non-small cell lung cancer, the most prevalent type of lung cancer. It originates from glandular cells that produce substances like mucus. The cancer typically begins in the outer regions of the lungs, impacting cells lining small airways or tiny air sacs called alveoli.
Risk factors for lung adenocarcinoma include smoking, but non-smokers can also develop the disease. Exposure to outdoor air pollution, especially fine particulate matter, is a significant risk factor. Other factors include secondhand tobacco smoke, radon, and workplace exposure to substances like asbestos. A family history of lung cancer can also increase risk.
Symptoms may not appear in early stages, making diagnosis challenging. When symptoms do occur, they resemble those of common respiratory illnesses. Persistent or worsening cough, chest pain, breathlessness, coughing up blood, unexplained weight loss, fatigue, and repeated respiratory infections are possible signs. Changes in voice may also occur. If the cancer spreads to other organs, symptoms can vary depending on the affected area.
Treatment depends on tumour characteristics and stage at diagnosis. It's crucial for individuals with risk factors to undergo regular check-ups and consult a doctor about any persistent symptoms.
