Why Should I Quit Smoking?

Most of us might have listened, watched or read about cigarette smoking and its harmful effects, but not have taken any action towards it. Somewhere in your lifetime, the effects of smoking may lead to a loss of life of you or your loved one due to the diseases caused by cigarette smoking. The deadliest of all, Lung Cancer, is on rise amongst males & females all over the world & India is no exception.

Cigarette Smoke – Breath Blocker, Heart Stopper & Cancer Trigger

Did you know?

  • Tobacco Smoke contains more than 7000 substances, out of which more than 250 are toxic & more than 70 substances are known to cause cancer.
  • Cigarette smoking claims lives of 6 million people all over the world, out of which 1 million are Indians.
  • In India, there are more than 70,000 diagnosed cases of lung cancer, more than 90% patients losing their lives.
  • Tobacco users, who die prematurely, deprive their families of income, raise the cost of healthcare & hinder economic development of the country.

Cigarette smoking increases the risk of developing

    • Lung cancer in men by 25 times
    • Lung cancer in women by 25.7 times
    • Heart disease (& heart attack) by 2-4 times
    • Stroke by 2-4 times
    • COPD & Asthma deaths – Smokers are 12-13 times more likely to die from COPD & asthma than non-smokers.

You don’t Smoke – Are you at a risk?

Second hand smoking, also called as Passive smoking/Involuntary smoking is a combination of side-stream smoke & smoke inhaled by the smoker. People are exposed to passive smoking at homes, workplaces & public places. There is no safe limit of smoking. Also there is no safe level of exposure to second hand smoke. Cigarette smoking increases the risk of developing –

  • Lung cancer by  20-30%
  • Heart disease by 20-30%
  • Stroke by 20-30%

Second hand smoke harms children

  • SIDS – Sudden Infant Death Syndrome is the sudden unexpected, unexplained death of the child in the first year of life
  • Triggering of Asthma attack in children
  • More chances of developing lung diseases – Bronchitis, Pneumonia
  • More chances of developing cough & wheeze
  • More chances of developing ear infections

So, does quitting help – even for a long-term smoker?

The good news is, yes! Becoming smoke-free is the first step towards reducing the risk of cancer.  It may not be easy and might require external help, but the health benefits far outweigh the damaging effects:

  • Staying smoke-free for 10 years reduces the risk of cancer in the lung by half of that of a smoker, along with reducing risk to others cancers as well.
  • Risk of heart attack falls sharply after 1 year of quitting smoking
  • Risk of stroke falls after 2-5 years of smoking
  • The life expectancy increases no matter what age a person stops smoking; however, the benefit is more if one quits earlier.

What about a person who already has a positive lung cancer diagnosis – will it help to quit smoking now?

The answer is yes, quitting smoking during treatment helps the body to respond to therapy and recover quicker, while also reducing the risk of other infections and respiratory failure. Cancer patients who quit smoking also reduce their risk of recurrent cancer or a second cancer at a later time.

Better late than never!
