Non-small cell lung cancer - Symptoms

Description

An in-depth report on the causes, diagnosis, treatment, and prevention of non-small cell lung cancer (NSCLC).

Alternative Names

Lung cancer - non-small cell; NSCLC

Symptoms:

Lung cancer is unlikely to produce symptoms until the disease is advanced. When symptoms develop, they may result from the lung tumor itself, from its effects on tissues outside the lung, or from the spread of cancerous cells to other organs.

Initial symptoms

The first symptoms of lung cancer may include some of the following:

Frequent bouts of pneumonia, or pneumonia that does not clear up in a normal period of time
Coughing (particularly coughing up blood)
Weight loss
Fever
Shortness of breath
Chest pain

Symptoms of Later Stages

Later-stage symptoms and complications include the following:

Shortness of breath: This common symptom is the result of cancer that has spread in the lung and the pleura -- the membrane covering the lung.
Superior vena cava syndrome: In some cases, tumor growth or spreading of the cancer presses against the superior vena cava, a large vein that returns blood from the upper part of the body to the heart. When this happens, a condition called superior vena cava syndrome may occur, leading to obvious swelling in the arms and face.
Trouble swallowing: The esophagus is the pipe that takes food from the mouth to the stomach. The cancer may spread to or press against the esophagus, interfering with swallowing and nutrition.
Hoarseness: Cancer can damage the nerves that control the voice box, causing hoarseness.
Pancoast syndrome: Damage to the brachial plexus, a group of nerves branching from the neck, can cause pain, weakness, or numbness in the arm or hand (Pancoast syndrome).
Bronchoalveolar lung cancer may produce very large amounts of mucus.
Hypercalcemia: Some lung cancers produce substances that remove calcium from bone and release it into the bloodstream, causing a condition called hypercalcemia. Patients with this disorder can experience nausea, vomiting, constipation, weakness, and fatigue.

Other lung cancers (usually small cell cancer) cause the body to retain water, lowering the blood's sodium levels. This condition, called hyponatremia, can produce confusion, weakness, and even seizures.
