6. Shortness of Breath or Wheezing
Shortness of breath and wheezing can indicate various conditions, including lung cancer.
Wheezing might be caused by a lung tumor pressing against and narrowing an airway.
5. Chronic cough and Chest Pain
Sometimes, lung cancer and leukemia symptoms mimic a bronchitis or a bad cough. The problem might appear occasionally, or be persistent. These symptoms can also be followed by chest pain extending down the arm, or into the shoulder. In such cases, make sure you make an appointment with a doctor as soon as you can.
In addition, if you cough and your voice is hoarse more than 6 weeks, consult your doctor. There are cases when hoarse voice indicates thyroid, lung, esophageal, or laryngeal cancer.
