Now, if we don’t take care of this organ, it will likely deteriorate. And the common disease it usually gets is lung cancer which is caused by smoking in most cases.
Smoking is the biggest risk factor because of more than 60 different toxic substances it contains which are carcinogenic or cancer-causing substances. The risk increases with the length of time and number of sticks you’ve smoked.
Apart from smoking, here are the other causes of this type of cancer:
- Passive smoking where non-smokers are being frequently exposed to tobacco smoke.
- Radon or the natural radioactive gas that is found in all rocks and soils due to small quantities of uranium present in them.
- Pollution and being exposed to certain hazardous chemicals like:
- arsenic
- asbestos
- beryllium
- cadmium
- coal and coke fumes
- silica
- nickel
- Genes may also be contributing factor. If you have come from a family with a history of lung cancer, it may also mean that you are at a higher risk of developing it as per an article from American Lung Association.
Accordingly, lung cancer doesn’t have symptoms during its early stages but symptoms will start to occur if it advances.
Among the symptoms to watch out for include a cough that doesn’t go away, coughing blood, shortness of breath, chest pain, hoarseness, loss of weight without even doing anything, bone pain, and headache.
