Lung Cancer Treatment: Options, What to Expect, and Support

Overview

Lung cancer is a condition where abnormal cells grow uncontrollably in the lungs, the organs that help you breathe. There are two main types: non-small cell lung cancer (NSCLC, which makes up about 85% of all lung cancer cases and tends to grow more slowly) and small cell lung cancer (SCLC, a more aggressive type that spreads quickly to other parts of the body). Treatment for lung cancer is personalized based on the type and stage of the cancer, your overall health, and your personal preferences. In recent years, advances in treatment have significantly improved survival rates and quality of life for many people with lung cancer.

Signs & Symptoms

Early-stage lung cancer often causes no noticeable symptoms. As the cancer grows, common signs and symptoms may include a persistent cough that does not go away, coughing up blood or rust-colored sputum, chest pain that worsens when you breathe or cough, shortness of breath, hoarseness, unexplained weight loss, persistent fatigue, and frequent lung infections like bronchitis or pneumonia.

Causes & Risk Factors

Smoking (including regular exposure to secondhand smoke) is the leading cause of lung cancer, responsible for 80 to 90% of all cases. However, people who have never smoked can also develop lung cancer. Other risk factors include long-term exposure to radon gas (a colorless, odorless radioactive gas that can seep into homes), asbestos, arsenic, or other cancer-causing chemicals, a family history of lung cancer, and previous radiation therapy to the chest.

Diagnosis

If your doctor suspects you may have lung cancer, they will order tests to confirm the diagnosis and determine the stage (how far the cancer has spread). Common diagnostic tests include a chest X-ray or CT scan to look for abnormalities in the lungs, a biopsy (where a small sample of lung tissue is removed and tested for cancer cells), and imaging tests like PET scans or bone scans to check if the cancer has spread to other parts of the body. The stage of your cancer is the most important factor in determining the best treatment plan for you.

Treatment & Management

Lung cancer treatment is tailored to your specific situation, including the type and stage of cancer, your overall health, and your treatment goals. Common treatment options include:

• Surgery: Removes the tumor and a small amount of surrounding healthy tissue, and is most often used for early-stage cancers that have not spread to other parts of the body.
• Radiation therapy: Uses high-energy beams (like X-rays) to kill cancer cells. It may be used as the primary treatment for early-stage tumors, to shrink tumors before surgery, or to relieve symptoms like pain or shortness of breath in advanced cases.
• Chemotherapy: Uses powerful drugs to kill fast-growing cancer cells. It is often used in combination with other treatments, or for cancers that have spread to other parts of the body.
• Targeted therapy: Uses drugs that target specific genetic mutations or changes in cancer cells. It is used for certain types of non-small cell lung cancer that have specific genetic markers, and often causes fewer side effects than chemotherapy.
• Immunotherapy: Uses drugs that help your immune system recognize and attack cancer cells. It is used for some advanced lung cancers, and has improved outcomes for many patients in recent years.
• Palliative care: A type of specialized care focused on relieving symptoms, pain, and stress related to cancer and its treatment, at any stage of illness. It is not the same as hospice care, and can be used alongside curative treatments.

Living With It

During and after lung cancer treatment, small, proactive steps can help you manage side effects and improve your quality of life: eat a balanced diet rich in fruits, vegetables, and lean protein to maintain strength; stay as physically active as your energy allows (short walks or gentle stretching are great options if you are fatigued); avoid all tobacco products and secondhand smoke to reduce strain on your lungs; and connect with a support group, mental health professional, or loved ones to cope with the emotional stress of a cancer diagnosis. Regular follow-up appointments with your oncology team are critical to monitor for cancer recurrence and manage any long-term side effects of treatment.
