Non-small cell lung cancer (NSCLC) is a form of cancer that begins in the lungs and usually affects older adults. It is the most common type of lung cancer, accounting for over 80% of cases.

NSCLC develops when cells in the lungs become abnormal and start to divide and grow quickly. The abnormal cells form a tumor, which can grow and spread throughout the body.

The exact cause of NSCLC is unknown but it is linked to a variety of risk factors, including smoking, exposure to asbestos, a family history of lung cancer, and age.

The primary symptom of NSCLC is a persistent cough. Other symptoms may include chest pain, weight loss, hoarseness, or coughing up blood. Diagnosis of NSCLC typically requires imaging tests such as a computerized tomography (CT) scan or positron emission tomography (PET) scan.

Treatment for NSCLC can include surgery, radiation therapy, chemotherapy, targeted therapy, and immunotherapy. Depending on the stage and type of cancer, treatments may be used alone or in combination.

It's important to remember that early detection of NSCLC is key to successful treatment. If you have any of the symptoms of NSCLC, contact your doctor as soon as possible. They will perform tests to diagnose NSCLC or another type of lung cancer.

Even though NSCLC is a serious illness, it can be treated if caught early. With new advancements in cancer treatments, more people are surviving for longer after being diagnosed with the disease. If you have been diagnosed with NSCLC, talk to your doctor about treatment options to give yourself the best chance for survival.
