Symptoms and Diagnosis of Lung Cancer

“Recurrent Episodic Chest Pain” is the earliest symptom of Lung Cancer. However, the most frequent cause of chest pain is cardio-vascular insufficiency i.e. heart attack which needs to be ruled out by an electrocardiogram. The pain in lung cancer is constant dull aching type while in heart attack it has a sharp shooting nature. As the tumor grows and invades the healthy tissue, its ability to transfer oxygen in the air to blood decreases and patient develops “shortness of breath”. Invasion by cancer cells makes the lung tissue non-functional. This dead tissue is invaded by air born bacteria causing “repeated episodes of pneumonia”.

As the invading cancerous tissue irritates the bronchus i.e. the windpipe, the patient develops “cough which doesn’t improve with medications”. If the cancer tissue erodes through the bronchus damaging its blood supply, patient “coughs up blood”. Metastatic spread of the cancer to distant places indicates failure of body defenses which leads to “loss of weight” and “tired feeling with lethargy”.
