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-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.
