The main symptoms of lung cancer are:
- a new cough or change in an ongoing cough
- chest pain
- repeated bouts of pneumonia or bronchitis
- coughing or spitting up blood
A person may have also experienced symptoms such as fatigue, weight loss, hoarse voice, wheezing, difficulty swallowing, and abdominal or joint pain.
Lung cancer symptoms can be vague and the disease is often discovered when it is advanced (has spread to other parts of the body). Having any one of these symptoms does not necessarily mean that you have cancer.
Some of these symptoms may be caused by other conditions or from the side effects of smoking. However, if you have symptoms, see your doctor without delay.
Sometimes, there are no symptoms and the cancer is found during routine tests (often an x-ray or CT scan) for other conditions. If so, the cancer is more likely to be in an early stage of development (confined to the lungs).
