The cases of lung cancer are on the rise, particularly among the urban population. In India alone, lung cancer constitutes 6.9 per cent of all new cancer cases, which is caused mostly due to smoking and air pollution.
Early treatment can help to reduce the number of fatalities, but the problem is that lung cancer is not easy to detect. Most cases of lung cancers do not cause any symptoms until they have spread to a large portion. At times, the initial symptoms are also confused with other conditions, which delays the treatment process. One of the early signs of lung cancer can be detected from the way you cough. So, if you are a smoker or think you are at risk of lung cancer, do not take the signs lightly. Here is what you have to look for.
