Incidence & Prevalence in Canada

  • In 2017, an estimated 2,900 new cases of multiple myeloma will be diagnosed and approximately 1,450 myeloma-associated deaths.
  • In the period from 2003 to 2012, the annual percentage rate in mortality rate was 0.9% in men and -1.8% in women. 
  • The average age at diagnosis is 62 years for men and 61 years for women, with only 4% of cases diagnosed in individuals under the age of 45.
  • The incidence of myeloma varies from country to country, from a low of fewer than one per 100,000 people in China, to a high of about four per 100,000 people in most western industrialized countries.  

Incidence, prevalence and mortality, what's the difference?

  • INCIDENCE: The number of new cases diagnosed in a year.
  • MORTALITY: The number of deaths attributed to cancer.
  • PREVALENCE: The total number of cases of a disease at a specific time.
  • Prevalence is influenced by both the incidence and the mortality rate. Prevalence increases when survival rates increase, even though incidence remains the same.
  • As multiple myeloma patients live longer, the prevalence increases.
