Incidence and Prevalence in Canada
- According to the 2016 Canadian Cancer Statistics report, there are approximately 7,455 people living with multiple myeloma in Canada.
- In 2016, an estimated 2,750 new cases of multiple myeloma were diagnosed and there were 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.
- Multiple myeloma accounted for an estimated average of 1.4% of all new cancer cases, and 1.8% of all cancer deaths in Canada, in 2016.
- Men slightly outnumber women in both the number of new cases (1,600 men compared to 1,150 women) and deaths (800 men compared to 640 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.
