Summary
Cancer prevalence in Canada is increasing, driven by an aging population and impacting various cancer types differently. This trend highlights the need for informed healthcare resource planning.
Area of Science:
- Epidemiology
- Public Health
- Oncology
Background:
- Cancer prevalence trends are underreported in scientific literature.
- No prior reports on cancer prevalence trends exist for Canada.
Purpose of the Study:
- To analyze and report on cancer prevalence trends in Canada.
- To identify variations in prevalence trends across different cancer types.
Main Methods:
- Utilized Canadian Cancer Registry incidence data.
- Integrated Canadian Vital Statistics Death Database mortality data.
- Calculated prevalence proportions over time by time since diagnosis for common cancers.
Main Results:
- Observed statistically significant increases in prevalence for most cancers and durations studied.
- Identified population aging as a contributing factor to increased prevalence.
- Noted substantial increases in liver and thyroid cancer prevalence, contrasting with decreases in laryngeal and cervical cancers.
Conclusions:
- Cancer prevalence trends vary significantly by cancer type.
- Understanding these trends is crucial for effective healthcare resource allocation planning.

01:21Cancer Survival Analysis
Cancer survival analysis focuses on quantifying and interpreting the time from a key starting point, such as diagnosis or the initiation of treatment, to a specific endpoint, such as remission or death. This analysis provides critical insights into treatment effectiveness and factors that influence patient outcomes, helping to shape clinical decisions and guide prognostic evaluations. A cornerstone of oncology research, survival analysis tackles the challenges of skewed, non-normally...
02:59Cancer Prevention
Several factors can increase the risk of cancer in an individual. About 50% of cancer cases can be prevented by adopting a healthy lifestyle, regular exercise, eating healthy, and following a modest cancer prevention diet. Epidemiological studies have consistently shown that populations with vegetable and fruit-rich diets have reduced the incidence of cancer. On the other hand, populations who have a diet rich in animal fat, red meat, junk food, or high calories are predisposed to cancer.

03:03mTOR Signaling and Cancer Progression
The mammalian target of rapamycin or mTOR protein was discovered in 1994 due to its direct interaction with rapamycin. The protein gets its name from a yeast homolog called TOR. The mTOR protein complex in mammalian cells plays a major role in balancing anabolic processes such as the synthesis of proteins, lipids, and nucleotides and catabolic processes, such as autophagy in response to environmental cues, such as availability of nutrients and growth factors.

02:07Tumor Progression
Tumor progression is a phenomenon where the pre-formed tumor acquires successive mutations to become clinically more aggressive and malignant. In the 1950s, Foulds first described the stepwise progression of cancer cells through successive stages.
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...
