Skin cancer is the most common form of cancer, globally accounting for at least 40% of cancer cases. [5] [20] The most common type is nonmelanoma skin cancer, which occurs in at least 2–3 million people per year. [6] [21] This is a rough estimate; good statistics are not kept. [1]
This is a list of countries by cancer frequency, as measured by the number of new cancer cases per 100,000 population among countries, based on the 2018 GLOBOCAN statistics and including all cancer types (some earlier statistics excluded non-melanoma skin cancer).
Cutaneous squamous-cell carcinoma is the second-most common cancer of the skin (after basal-cell carcinoma, but more common than melanoma). It usually occurs in areas exposed to the sun. Sunlight exposure and immunosuppression are risk factors for SCC of the skin, with chronic sun exposure being the strongest environmental risk factor. [26]
Skin cancer has three main forms: basal cell carcinoma, squamous cell carcinoma and melanoma. The first two are the most prevalent forms. [ 23] Although generally non-melanoma carcinomas have lower associations with mortality than melanomas, fatalities occur, with 534 reported deaths in 2011.
Melanoma is the most dangerous type of skin cancer.[2] Globally, in 2012, it newly occurred in 232,000 people.[2] In 2015, 3.1 million people had active disease, which resulted in 59,800 deaths. [5][6]Australia and New Zealand have the highest rates of melanoma in the world.[2]
Basal-cell carcinoma ( BCC ), also known as basal-cell cancer, basalioma [7] or rodent ulcer, [8] is the most common type of skin cancer. [2] It often appears as a painless raised area of skin, which may be shiny with small blood vessels running over it. [1] It may also present as a raised area with ulceration. [1]
For 40 years, The Skin Cancer Foundation has been awarding research grants to physicians and investigators to support pilot research projects related to prevention, detection and treatment of skin cancer. Since 1981, many of the grantees' studies have led to important breakthroughs. SCF has funded more than $1.8 million in grants as of 2020.
Cancer mortality rates are determined by the relationship of a population's health and lifestyle with their healthcare system. In the United States during 2013–2017, the age-adjusted mortality rate for all types of cancer was 189.5/100,000 for males, and 135.7/100,000 for females. [ 1] Below is an incomplete list of age-adjusted mortality ...
