Definition of the Lung Tumors

Lung tumors are abnormal growths of cells that form in the lungs. They can be benign (noncancerous) or malignant (cancerous). Benign tumors are not usually life-threatening and can often be removed surgically. Malignant tumors, however, can spread to other parts of the body and are more difficult to treat. The most common type of lung tumor is non-small cell lung cancer (NSCLC). This type of cancer is divided into three subtypes: adenocarcinoma, squamous cell carcinoma, and large cell carcinoma. Adenocarcinoma is the most common type of NSCLC and is usually found in the outer parts of the lungs. Squamous cell carcinoma is found in the middle of the lungs and is usually more aggressive than adenocarcinoma. Large cell carcinoma is the least common type of NSCLC and is found in any part of the lungs. Other types of lung tumors include small cell lung cancer (SCLC), which is more aggressive and spreads quickly; bronchoalveolar carcinoma, which is a type of adenocarcinoma; and carcinoid tumors, which are slow-growing tumors that usually don’t spread. Lung tumors are usually diagnosed with imaging tests such as X-rays, CT scans, and MRI scans. Biopsies may also be used to confirm the diagnosis. Treatment for lung tumors depends on the type and stage of the cancer. Surgery, chemotherapy, and radiation therapy are all possible treatments. Lung tumors can be life-threatening, so it’s important to seek medical attention if you experience any symptoms such as a persistent cough, chest pain, or shortness of breath. Early diagnosis and treatment can help improve outcomes and increase the chances of a successful recovery.
