When you quit smoking some benefits are immediate, such as:

  • Blood pressure and heart rate return to normal within 20 minutes
  • 8 hours after your last cigarette your carbon monoxide levels in your blood drop, your blood oxygen improves and breathing is easier
  • Risk of heart attack drops within 24 hours of quitting and your lungs will start to clear out mucus
  • Within 48  hours your sense of smell and taste improve, so you will probably start to enjoy food more
  • Energy levels start to improve three days after stopping smoking
  • Improved immune response

Quitting smoking leads to:

  • Improved treatment outcomes
  • Reduced side effects
  • Decreased risk of infection
  • Improved breathing and increased energy
  • Improved quality of life

Continued tobacco use after a cancer diagnosis leads to:

  • Higher rates of complications from surgery, and slower recovery
  • Higher treatment related toxicity from chemotherapy and radiation therapy
  • Increased risk of cancer recurrence
  • Increased risk of heart and lung disease
  • Reduced treatment effectiveness
  • Increased risk of a second cancer
  • Shorter survival

Conclusions from the 2014 Surgeon General’s report  include:

  • In cancer patients and survivors quitting smoking improves health outcomes
  • Smoking increases the risk for  recurrence, poorer response to treatment, and increased treatment related toxicity

Evidence suggests that the risk of dying can be lowered 30-40% by quitting smoking at the time of a cancer diagnosis.  For some cancer diagnosis the benefits of quitting smoking may be equal to cancer treatments.

Quitting smoking during your cancer experience is a very difficult time, however it is a very important time to quit smoking.  Smoking during cancer treatment can lead to less effective treatment and more severe side effects from the treatment. This is because of chemicals in the smoke, not the nicotine. If you are receiving care at Grand River Regional Cancer Centre and would like support to reduce or stop smoking you can:

  • Speak to your health care provider about quitting smoking;
  • Call our Tobacco Cessation Clinic (519-749-4370 ext. 3848) to speak with our staff about the supports available to you including counseling, medication or both. Our quit coach can help you identify local opportunities that offer free nicotine replacement, such as nicotine patches; or
