All You Need To Know About Lung cancer and it’s preventions
Lung cancer is a type of cancer that affects the lungs. Your lungs are two spongy organs in the human chest that takes in oxygen when you inhale, and it releases carbon dioxide when you exhale. Lung cancer is the leading cause of cancer deaths all over the world.
According to researches, smoking causes majority of lung cancer cases recorded; both in smokers and people exposed to second hand smokes. But lung cancer also occurs in people who never smoked and in those who never had long exposure to second hand smoke. In these cases there may be no clear causes of lung cancer.
HOW SMOKING CAUSES LUNG CANCER
Doctors believe smoking causes lung cancer by damaging the cells lined in the lungs. When you inhale cigarette smoke, which is full of cancer-causing substances like carcinogens, changes in the lungs begin almost immediately.
At first your body may be able to repair the damages done, but, with each repeated exposure, normal cells in the lungs begin to increasingly get damaged. Overtime, the damage causes cells to act abnormally and eventually cancer may develop.
There’s no sure way to prevent lung cancer, but you can reduce your risk if you:
- Don’t smoke.
If you’ve never smoked, don’t start. Talk to your children about not smoking so that they can avoid this high risk factor for lung cancer. Begin conversations about the dangers of smoking with your children early so that they know how to react to peer pressure.
- Stop smoking.
Stop smoking now. Quitting reduces your risk of lung cancer, even if you’ve smoked for long. Talk to your doctor about strategies to aide in smoke stopping. Options include nicotine replacement products, medications and support groups.
