Module 3 - Prevalence Flashcards
What is the global cancer burden in terms of new cases and deaths according to GLOBOCAN in 2018?
In 2018, worldwide, there were 18,078,957 million new cancer cases (2.4 cases per 1,000 people) and 9,555,027 million cancer deaths, with 43,841,302 million people living with cancer (diagnosed in the past 5 years).
How is the global cancer burden shifting in terms of regions?
The global cancer burden is shifting from more developed countries to economically disadvantaged countries.
Where can one find Canadian cancer statistics, and what do they reveal about cancer in Canada?
Canadian cancer statistics are compiled by the Government of Canada and can be found at https://www.cancer.ca. Approximately 2 in 5 Canadians will develop cancer within their lifetime, and about 1 in 4 Canadians will die of cancer. In 2020, there were estimated to be about 225,800 new cancer diagnoses in Canada, with approximately 83,300 deaths from cancer.
What are the leading types of cancer in Canada, and which one is the leading cause of cancer death?
The leading types of cancer in Canada are lung, breast, colorectal, and prostate cancer. Lung cancer is the leading cause of cancer death in Canada.
How has the lung cancer death rate changed in Canada over the past 25 years, and what factors may have contributed to this change?
The lung cancer death rate in Canada has dropped, especially for men, over the past 25 years. This decline may be related to changes in lifestyle habits, such as smoking cessation, which have resulted in an overall decline in the cancer death rate since the early 1990s.
What percentage of lung cancers are preventable, and what is the primary attributable factor for lung cancer?
An estimated 86% of lung cancers are preventable, and 72% of them are attributable to tobacco smoke, highlighting the importance of prevention efforts. Reducing mortality for this disease also requires improvements in treatment.
Why is measuring the cancer burden in Canada important?
Measuring the cancer burden in Canada is crucial because it informs research priorities and resource allocation for the effective treatment and management of cancer. It helps identify areas where prevention and treatment strategies can have the most significant impact.
According to the World Health Organization (WHO), what is the most effective long-term strategy for preventing cancer?
The World Health Organization (WHO) suggests that prevention is the most effective long-term strategy for preventing cancer.
What is the most commonly diagnosed cancer in Canada (excluding non-melanoma skin cancers)?
Lung and bronchus cancer is the most commonly diagnosed cancer in Canada (excluding non-melanoma skin cancers).
Lung and bronchus cancer is the most commonly diagnosed cancer in Canada (excluding non-melanoma skin cancers).
Lung and bronchus cancer is the leading cause of death from cancer for both men and women in Canada.
What does “incidence” in cancer statistics refer to?
Incidence is the total number of new cases of cancer.
What does “mortality” in cancer statistics refer to?
Mortality is the number of deaths due to cancer.
How many Canadians are estimated to be diagnosed with lung and bronchus cancer in 2022?
In 2022, an estimated 30,000 Canadians will be diagnosed with lung and bronchus cancer.
How many Canadians are estimated to die from lung and bronchus cancer in 2022?
In 2022, an estimated 20,700 Canadians will die from lung and bronchus cancer.
How does the incidence and mortality of lung and bronchus cancer differ between men and women in Canada in 2022?
In 2022, an estimated 15,000 men will be diagnosed with lung and bronchus cancer, with 10,600 deaths. For women, there will be an estimated 15,000 diagnoses and 10,100 deaths.
What is the 5-year net survival rate for lung and bronchus cancer in Canada (estimates for 2015 to 2017)?
The 5-year net survival rate for lung and bronchus cancer in Canada is estimated to be 19% for males and 26% for females.
When did the rate of new lung and bronchus cancer cases begin decreasing in Canadian men and women, and why do these trends differ?
In Canadian men, the rate began decreasing in 1990. In women, it started decreasing in 2013. These differences are likely due to variations in tobacco use, with more men smoking than women.
What is the estimated probability of developing or dying from lung and bronchus cancer for Canadian men and women?
It is estimated that about 1 in 15 Canadian men will develop lung and bronchus cancer during their lifetime, with 1 in 18 dying from it. For Canadian women, the estimates are about 1 in 15 developing it and 1 in 20 dying from it during their lifetime.
What is the most common cancer among Canadian women (excluding non-melanoma skin cancers)?
Breast cancer is the most common cancer among Canadian women (excluding non-melanoma skin cancers).
What is the second leading cause of death from cancer in Canadian women?
Breast cancer is the second leading cause of death from cancer in Canadian women.
