Cancer Prevention

Amazingly, 2 out of 3 cancer deaths are preventable by diet and lifestyle changes alone!

30% of all cancer deaths
are caused by:

This 2016 study published in the Journal of the American Medical Association found that one third of all cancers were caused by smoking.

  • 90% of Lung cancers are caused by smoking
  • 50% of all smokers will die from smoking related diseases
  • Smokers have an increased risk of cancers, heart disease, strokes, and many other diseases

How to quit.

This 2018 study, published in the British Medical Journal shows that people trying to quit smoking will be much more successful if they use  Allen Carr’s Easyway to Stop Smoking rather than the Irish Government initiative Quit.ie

Cancer Ireland Editor’s note:
I have no association with Allen Carr’s Easy Way to Stop Smoking, but I’m happy to promote this method because I found it to be extremely helpful and effective in helping me to quit smoking after 30 years.

If you quit smoking right now…

After 5 years: Your risk of cancer of the mouth, throat, esophagus, and bladder are cut in half. Your risk of cervical cancer and stroke return to normal after 5 years.
After 10 years: You are half as likely to die from lung cancer. Your risk of larynx or pancreatic cancer decreases.
