A person with lung cancer may have the following symptoms:
1. Persistent cough or changes in cough
If you have a cold, your cough should go away after a week or two, but if it persists over a long time, you should see your doctor. If you are a smoker or suffers from chronic cough, notice if there are any changes in your chronic cough, for example: coughing more frequently, deeper cough with a deeper or hoarse sound, coughing up blood or having more mucus than usual.
2. Shortness of breath: If you are short of breath while doing a task that you could have done easily in the past, it may be a symptom of lung cancer. This symptom can occur if lung tumor blocks or narrows an airway, or if fluid from it builds up in the chest.
3. Chest and bone pain: One of the symptoms may be pain in the chest, shoulder, or back area. Lung cancer that has spread to the bones may cause pain at the sites of the affected bone. If it has spread to the brain it may cause a number of neurological symptoms and headaches. So listen to your body and if the pain persists and doesn’t go away, go to see your doctor
4. Wheezing: While a whistling sound when you breathe can result from asthma or allergies, it can also be associated with lung cancer. If wheezing persists, visit your doctor to find the cause of it.
5. Voice changes: Your voice becomes hoarser and deeper or you notice any other significant changes in your voice. While hoarseness can result from a simple cold, if it persists then go to see your doctor.
6. Persistent chest infections : Infections such as bronchitis and pneumonia that don’t go away or keep coming back.
7. Weight loss, loss of appetite, fatigue and weakness: These are non-specific symptoms that can be seen with many other cancer types or other diseases, but if the changes are unexplained and persist, then go to your doctor to find the cause of it.
