Some lung cancer symptoms include a cough that doesn't go away with or without blood, chest pain, shortness of breath or wheezing, hoarseness and unexpected weight loss, according to Mayo Clinic. Symptoms often don't start appearing until the lung disease becomes advanced.

A chronic cough doesn't necessarily mean the patient has lung cancer. Coughs associated with cancer are often new and don't go away. In patients who already have a chronic cough, lung cancer may cause a change in the cough, says Mayo Clinic. Blood that comes up with the cough doesn't have to be in large quantities. Even small amounts of blood can occur with lung cancer.

As the disease advances, the patient may notice additional symptoms. This is typically due to the disease spreading to other parts of the body, according to the American Cancer Society. Potential symptoms include pain in the bones, jaundice, swollen lymph nodes or nervous system symptoms, such as headaches, weakness or dizziness.

Cancer near the top of the lungs sometimes affects a nerve that goes into the neck, states the American Cancer Society. When this occurs, the patient may experience shoulder pain, eyelid drooping or weakness, a smaller pupil or decreased sweating in the face. Tumors in the upper right lung sometimes press against the superior vena cava, causing swelling or skin discoloration in the face, upper chest, neck and arms.
