Doctor's Notes on Lung Cancer
- shortness of breath,
- chest pain,
- persistent cough and/or coughing up blood,
- wheezing or hoarseness and
- respiratory infections.
Indirect signs and symptoms due to chemicals released from the cancer cells may include
- finger clubbing,
- new bone formation,
- blood clots, or nervous system degeneration and
- electrolyte abnormalities.
There are many different types of lung cancers but most share these signs and symptoms.
Lung cancer is caused by abnormal growth and multiplication of lung cells; this is considered primary lung cancer while many other cancers in the lungs are due to metastatic cancer cells that originated in organs other than the lung that traveled through the body to reach the lungs. About 90% of lung cancers are due to smoking; other potential causes are air pollution, asbestos exposure, radon exposure, and lung diseases such as tuberculosis. Exposure to arsenic, chromium, nickel, ethers, and aromatic hydrocarbons increase the risk of developing lung cancer.
