Host response, signs and symptoms of lung cancer.

One of the symptoms of lung cancer are Cough Doesn’t Go Away. One of the most common signs of lung cancer is a persistent cough. It may seem obvious that this symptom should be checked out, but it is often attributed to something else. Perhaps you think it is allergies or just another winter cold, or that if you just wait another week, it will go away. Even if it seems like there is a simple reason for your chronic cough, if it is lasting, get it checked out.

One of the other symptoms is coughing up blood. There are many conditions that will cause cough blood. One of them is Lung cancer.

Shortness of breath is also one of the symptoms of the Lung Cancer. You maybe thought that you are a little older than other people or have decreased ability to climb up stairs without catching your breath. Tell it to your doctor if your have this symptom.

Other symptom is recurrent pneumonia and bronchitis. Lung cancer can cause pneumonia. It can be difficult to diagnose when the lung infections occur. Changes in X-ray caused by pneumonia can make it difficult to see the cancer cells in some cases. If you found out that you have lung infections, ask your doctor if you need to be checked out for further more details.

Lung cancer also can cause pain in your chest and back. Certainly, symptoms of pain in your chest or back are more likely to be related to a cause other than lung cancer. Most of us have had back pain after lifting someone we probably shouldn’t have. But pain that persists, especially if you can’t think of any reason for that pain, should prompt a call to your doctor. Chest pain related to lung cancer tends to be constant rather than intermittent, and may worsen with time.

Lung cancer also can cause pain in your shoulder. When lung cancer grows more nearer to the top of the lungs, they can put pressure on nerves in your armpit. This will cause the pain to go inside of the arm down to the hands.

Lung cancer also can cause weight loss without trying. Losing of weight is just a normal thing in daily life, but if your weight decreases without eating less or exercise, there must be something wrong with your body. Cancer can cause change in metabolism in your body so that weight loss occurs even you eat a proper calories of food.

But if the lung cancer has spread to other parts of the body, others symptoms may also occur. The patient will also get headache if the brain is also affected. The person will also get stroke. Difficulty in swallowing is also the symptoms of lung cancer. The voice of the person will also change (persistent hoarseness and clearing throat often). The fingernails of the patient will also experience clubbing as a result of lung cancer (fingernails become rounded).
