Whenever a word lung cancer strikes our ears, we immediately point our finger towards the frequent smokers. Four out of five people today becomes the victim of lung cancer. According to the study, chances of lung cancer in non-smokers is more than that of chain smokers.
Abnormal and unrestrained division of cells in body parts leads to cancer. This division can even alter the genetic structure of the cell. Moreover, intake of carcinogenic substances boosts the speeding up of cell division.
Smoking is a primary action of developing lung cancer in chain smokers. But, study says around 10 to 15 percent of non-smokers in the US are diagnosed with lung cancer. Have you ever thought what can be the reason behind this?
Second-hand smoking or indirect smoking is the cause of lung cancer in non-smokers. They are two basic types of second-hand smoking. One is due to slow burning of bidi, hookah, and cigar and other type include those who inhale the smoke given out by other chain smokers.
Seventy chemicals in indirect smoking are cancer-causing and life-threatening. Hence, decreasing the levels of second-hand smoking is of prime importance. Educating the people, conducting useful seminars and spreading health awareness are the ways to make people realize the hindrances of smoking whether it may be direct or indirect.
Symptoms of lung cancer:
- A cough shedding out blood
- Determined coughing
- Difficulty in breathing
- Unnecessary and mysterious weight loss
Dr. Geoff Oxnard, a specialist in lung cancer says, “Detecting cancer in older people with X-ray scans is much easier as they are already very sick all the time. Hence, they do regular checkups. But, this doesn’t happen with youngsters. They are already very fit and fine. They rarely do their medical checkup. Hence, detection of cancers in young people is really sometimes a challenging job. The symptoms are usually overlooked.”
What precautions should we take?
- Avoid polluting the air, as it may contain high traces of carcinogens.
- Avoid public smoking
- Avoid exposure to radon gas
