What is mortality, incidence, and prevalence?
Mortality - # of deaths / year
Incidence - # new cases diagnosed / year
Prevalence # individuals with cancer within a certain period / year
How much does cancer account for the deaths in Canada?
Cancer accounts for 29.9% of deaths in Canada since 2011. This is the leading cause of death and beat out CVD which used to be the leading cause.
How does the incidence rate compare to the death rate in both men and women?
There is an increase in diagnosis in both men and women and the slope is a lot steeper, whereas the slope for mortality is a lot lower less steep.
What are the top four cancers among men and women?
Colorectal cancer and lung cancer are both in the top three cancers for both men and women. Prostate cancer is in the top three for men and breast cancer is in the top three for women.
Why is the theory behind the cause of cancer in of the prostate and breast?
The theory behind the endocrine gland cancer is that we have endocrine disrupting chemicals that affect these glands
What are some cancer stats mentioned in the lecture?
196, 900 Canadians will be diagnosed with cancer in 2015
2 in 5 Canadians will develop cancer in their lifetime
1 in 4 Canadians will die from cancer (est, 78000)
What cancer is increasing in incidence in Canadians?
Thyroid cancer is the highest
Some others that are increasing include larynx, melanoma, liver and stomach
What cancer is increasing in mortality in Canadians?
Thyroid is the highest
Some other that are increasing include stomach, liver, larynx, and melanoma
What are the most common cancers among ages 0-14? Which is becoming of great concern and why?

Prostate, breast and lung

Lung, colorectal and prostate
What are the main causes of lung cancer?
Tobacco/cigarette smoking, asbestos exposure and possibly radiation
Why is lung cancer detection so late?
Lung cancer is asymptomatic in 90% of individuals - symptoms are not prevalent
They are masses in the lung, and you can appear perfectly healthy
It is when it metastasizes that it becomes detected
What characteristic do many carcinogens have?
They are liposoluble, so they can penetrate our skin, organs and other body parts quite easily
What are some associations of tobacco and cancer?
Cigarette smoking is responsible for 30% of all cancer deaths
Strongest association with squamous cell carcinoma of the lung
Strong risk factor for cancers of the lower urinary tract, upper GI tract, liver, pancreas, cervix and leukemia
Secondary (environmental) tobacco smoke increases risk for lung cancer
Describe the Public Health Initiatives work
Cigarette consumption grew rapidly during the first half of the last century and began declining beginning with the Surgeon General's 1964 report that tied lung cancer to smoking. While a number of factors, including advertising and distribution of free cigarettes in army rations, drove up smoking in the early part of the century, a range of public antismoking policies implemented beginning in the 1970s (beige boxes), including tobacco tax increases, smoke-free laws, warning labels and advertising bans, has successfully driven down cigarette consumption in the latter half of the century. There is usually a 20- to 30-year lag time between the onset of smoking and the development of lung cancer, and the causal connection between tobacco use and lung cancer is clearly seen in the parallel trends of cigarette use and the corresponding incidence of male lung cancer, peaking and declining with lag time of approximately 20 years
