treatments all matter.
A lung tumor also cannot be reliably evaluated by looking at symptoms alone. A person may have a persistent cough, coughing up blood, chest discomfort, shortness of breath, unexplained weight loss, recurrent respiratory infections, or ongoing fatigue. These symptoms can have many causes, but persistent or worsening symptoms deserve medical evaluation.
When doctors suspect lung cancer, they may use imaging such as a chest CT scan to examine the lungs. If a suspicious mass is found, additional testing may be necessary to determine whether it is cancer and, if so, what type it is.
