The lung cancer is among the most frequent causes of death in the world. It occurs because of uncontrolled cell growth in lung tissue and if left untreated can spread to other parts of the body as well.
The smoke is the number one risk factor for getting lung cancer, but it can also develop in people who have never smoked. People who have a family history of lung cancer, especially a parent or a sibling, they are at greater risk. Other risk factors include exposure to secondhand smoke or noxious gases. Lung cancer occurs mostly in older people, almost 70% of people who have contracted over 65 years, while 3% are less than 45 years. Lung cancer is responsible for approximately 27% of all cancer deaths each year. More people die of lung cancer than in colon cancer, breast and prostate cancer combined.
This is because this cancer is diagnosed at an advanced stage that makes it more difficult to treat. In many cases, it may not be any noticeable symptoms in the earlier stages. Therefore it is essential to understand the possible signs and symptoms, and consult your doctor when the disease is still in the early stages. Here are the 10 symptoms of lung cancer do not ignore.
1. Chronic Cough
We all suffer from cold and cough from time to time. But if you have a chronic cough that lasts more than three weeks and no symptoms of cold, it may be an early sign of lung cancer. Often patients complain of chest pain that extends up to the shoulder or down the arm during cough, which may be dry or produce mucus. If you have a persistent cough that lasts for weeks and does not respond to medication, consult your doctor.

If you experience a sudden shortness of breath, do not take it lightly and consult your doctor.
5. Bone and Chest Pain
The chest pain that worsens with coughing, laughing or deep breathing is often an early symptom of lung cancer. This happens when the cancer spreads to the lining of a lung. In advanced stages, the cancer can spread to the bone and you may even feel pain in your back, arms, neck, shoulder or other body areas. This type of pain often worsens at night to rest lying on your back. The duration and severity of the pain can vary depending on several factors, including local effects of the tumor and its spread.
