Melanoma Stats and Facts
MELANOMA STATS & FACTS
The leading cause of melanoma is the over exposure to ultroviolet (UV) radiation from the sun or artificial sources. Exposed human skin can tan or burn – both are signs of damage to the underlying cells. A burn, in particular, is a marker of extensive damage that normal DNA repair mechanisms may not be able to repair. Sunburn at any age is an indicator of UVR overexposure (generally intermittent exposure) and increases the risk of skin cancer, particularly of melanoma.
Melanoma Facts
- Melanoma is a very serious and potentially deadly form of skin cancer and is one of the few cancers with incidence rates on the rise.
- The survival rate for melanoma is high if it is detected early and unlike many cancers, melanoma is often clearly visible on the skin.
- Melanoma can affect anyone regardless of sex, age or race.
- The leading cause of melanoma is overexposure to ultraviolet (UV) radiation from the sun or artificial sources (tanning beds, sunlamps) [1].
- A single blistering sunburn before the age of 20 increases the risk of developing melanoma later in life.
- One indoor tanning session can increase the risk of skin cancer (Ontario Sun Safety Working Group)
- UV exposure can lead to skin damage such as early wrinkling and photoaging [2].
-
UV-emitting tanning devices are now also classified as carcinogenic to humans based on their association with skin and ocular melanoma cancers [3].
Melanoma Stats
- Melanoma is one of the most common cancer types found in young adults aged 15-29[4] and 30-49 [4].
- Melanoma is the 7th most commonly diagnosed cancers in Canada [4].
- In 2019, approximately 7,800 (4,300 males and 3,500 females) Canadians will be diagnosed with melanoma.[4]
- In 2019, it is estimated that 1,300 Canadians will die from melanoma. 840 males and 450 females [4].
- According to World Health Organization (WHO) 85% of melanomas among Canadian men and women aged 30+ years are attributed to UV radiation exposure. [5]
- Early exposure to tanning beds can increase a person’s chance of developing melanoma by up to 75%. [6]
- Artificial tanning devices emit 15x the amount of UV rays as from sun exposure [7]
- Outdoor workers are up to 2.5 to 3.5 times more likely to be diagnosed with skin cancers (Ontario Sun Safety Working Group)
CANADIAN CANCER STATS 2019 OVERVIEW
All statistics are from Canadian Cancer Statistics 2019
7,800 Canadians will be diagnosed with melanoma in 2019
Projected new cases for melanoma, by sex and province, Canada
*Canada totals include provincial and territorial estimates. Territories are
not included separately due to small numbers.
** Quebec was not included because a different projection method
was used for Quebec than the other regions, meaning the
estimates are not comparable. See Appendix II: Data source and
methods for additional details.
Melanoma is on the Rise
In males, the incidence rate for melanoma has increased steadily at about 2.2% per year since 1984. In females, the incidence rate for melanoma was stable from the mid-1980s to the mid-1990s, but it began increasing after 1994 (2.0%). Exposure to ultraviolet (UV) radiation through sunlight, tanning beds and sun lamps is a well established risk factor for melanoma.(23) Other risk factors include having a fair complexion, the number and type of moles, personal and family history of skin cancer, a weakened immune system and a history of severe blistering sunburns.

840 males
450 females
Lifetime Probability of dying from melanoma by gender, Canada, 2019
1 in 219 males
1 in 402 females
Melanoma is one of the most common cancer deaths for youth aged 15-29 and young adults 30-49. It accounts for 4% of all cancer deaths for both age categories.
Mortality Rates on the Rise
With the rising number of new cancer cases, there will be a corresponding increase in the need for screening, diagnostics, treatment and support services, including palliative care. It will also be important to promptly develop strategies to address the cancers that are showing significant increases in incidence rates, such as liver, thyroid and melanoma.

Canadian Cancer Statistics 2019 Appendix II note: Non-melanoma skin cancers (neoplasms, NOS; epithelial neoplasms, NOS; basal and squamous) are not included since most PTCRs do not collect incidence data on this type of cancer. These cancers are difficult to register because they may be diagnosed and/or treated in a variety of settings that do not report to the PTCRs, including dermatologist offices.

Tanning Beds are Dangerous
In 2009, WHO’s International Agency for Research on Cancer (IARC) classified exposure to UV-emitting tanning devices as carcinogenic to humans.
