The percent of new US cancer cases by age, 2023. The epidemiology of cancer is the study of the factors affecting cancer, as a way to infer possible trends and causes. The study of cancer epidemiology uses epidemiological methods to find the cause of cancer and to identify and develop improved treatments.
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).
SEER collects and publishes cancer incidence and survival data from population-based cancer registries covering approximately 34.6% of the population of the United States. SEER coverage includes 30.0% of African Americans, 44% of Hispanics, 49.3% of American Indians and Alaska Natives, 57.5% of Asians, and 68.5% of Hawaiian/Pacific Islanders. [3]

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 rates for different types of cancer in the United States from the Surveillance, Epidemiology, and End Results program.
In epidemiology, prevalence is the proportion of a particular population found to be affected by a medical condition (typically a disease or a risk factor such as smoking or seatbelt use) at a specific time. [1]
Breast cancer incidence by age in women (UK) 2006-08 [21] Breast cancer is the most common cancer in the UK (around 56,000 women and 375 men are diagnosed with the disease every year). It is the fourth most common cause of cancer death (around 11,400 women and 85 men die each year) and the second most common cause of death in women. [22]
Incidence (epidemiology) vs. Prevalence vs. Cumulative incidence; Many medical tests (such as pregnancy tests) have two possible results: positive or negative. However, tests will sometimes yield incorrect results in the form of false positives or false negatives.
