How to Spot and Diagnose Lung Cancer
While lung cancer can be life-threatening, early detection and modern treatments are improving outcomes for many people. Knowing the common signs and treatment for lung cancer can make a big difference. Keep reading to become informed.
Common Signs and Symptoms of Lung Cancer
Lung cancer often doesn’t cause symptoms in its early stages, which is why regular check-ups and screenings (especially for smokers or those at high risk) are so important. As the disease progresses, certain signs can appear. Here are the most common symptoms to watch for:
1. Persistent Cough
A cough that doesn’t go away or gets worse over time is one of the most common early symptoms. It may be dry or produce mucus.
2. Coughing Up Blood
Even a small amount of blood in your sputum (mucus) can be a warning sign. This symptom should always be checked by a doctor.
3. Chest Pain
Pain in the chest that gets worse when coughing, laughing or breathing deeply may be related to lung cancer, especially if it's persistent.
4. Shortness of Breath
If you find it harder to breathe or get winded doing activities you used to manage easily, it could be a sign that a tumor is affecting your lung function.

5. Wheezing
A whistling sound when breathing can be caused by a blockage or inflammation in the lungs.
6. Hoarseness
A change in your voice, especially if it becomes raspy and lasts more than a few weeks, may be due to pressure on the vocal cords from a tumor.
7. Unexplained Weight Loss
Losing weight without trying—especially if it happens quickly—can be a sign of cancer, including lung cancer.
8. Fatigue
Extreme tiredness that doesn’t improve with rest could indicate your body is using energy to fight disease.
9. Frequent Lung Infections
Repeated bouts of bronchitis or pneumonia could be a sign that a tumor is blocking part of the airway and making the lung more prone to infection.
Treatment Options for Lung Cancer
Treatment depends on the type of lung cancer (non-small cell or small cell), how far it has spread (the stage) and your overall health. Here are the main types of treatment available:
1. Surgery
If the cancer is found early and hasn’t spread, surgery may be an option to remove the tumor and part of the lung. There are several surgical approaches:
- Lobectomy. Removes one section (lobe) of the lung.
- Pneumonectomy. Removes an entire lung.
- Segmentectomy or wedge resection. Removes a smaller part of the lung.
Recovery takes time, but surgery can offer a potential cure in early-stage cases.
2. Radiation Therapy
Radiation uses high-energy beams (like X-rays) to kill cancer cells. It may be used:
- Before surgery to shrink tumors.
- After surgery to kill remaining cancer cells.
- As the main treatment when surgery isn’t possible.
- To relieve symptoms like pain or breathing problems in advanced cases.
3. Chemotherapy
Chemotherapy uses drugs that travel through the bloodstream to kill cancer cells. It’s often used:
- Along with radiation (especially for small cell lung cancer).
- Before or after surgery.
- To treat cancer that has spread to other parts of the body.
Side effects may include nausea, fatigue, and hair loss but newer drugs have made these more manageable.
4. Targeted Therapy
Some lung cancers have genetic mutations that can be treated with drugs designed to “target” those specific changes. These pills or infusions block the cancer’s ability to grow and spread.
Targeted therapy tends to cause fewer side effects than chemotherapy and is usually given to people whose tumors have certain genetic markers (like EGFR, ALK or ROS1 mutations).
5. Immunotherapy
This newer treatment helps the body’s immune system recognize and attack cancer cells. It’s used for some non-small cell lung cancers, especially in later stages.
Drugs like Keytruda (pembrolizumab) and Opdivo (nivolumab) have helped many patients live longer with fewer side effects than traditional chemotherapy.
6. Palliative Care
For people with advanced lung cancer, palliative care focuses on improving quality of life. This includes managing pain, shortness of breath, and emotional support. It can be given alongside other treatments.
Final Thoughts
Lung cancer is a serious diagnosis, but advances in screening and treatment are offering more hope than ever before. Recognizing the symptoms early and seeking prompt medical attention can lead to better outcomes. If you or a loved one are experiencing any of the signs listed above, don’t wait; talk to a healthcare provider. Early action can make all the difference.
