Cancer Prevention02:59

Cancer Prevention

7.5K
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.

Assessment of the Rectum and Anus01:25

Assessment of the Rectum and Anus

940
Evaluating the rectum and anus plays a crucial role in conducting a thorough physical examination of the gastrointestinal system. Although it may be uncomfortable and often embarrassing for the patient, it holds immense diagnostic value, particularly in detecting gastrointestinal diseases and abnormalities. This guide will explain how to perform this assessment using inspection and palpation methods.
Rectal Inspection
Begin by inspecting the perianal and anal areas for color, texture, rashes,...

Cancer Survival Analysis01:21

Cancer Survival Analysis

592
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...

Prevalence and Incidence01:08

Prevalence and Incidence

1.4K
In statistical epidemiology and health sciences, two essential metrics—prevalence and incidence—are fundamental for understanding disease dynamics within a population. These measures enable public health officials, epidemiologists, and researchers to assess the burden of diseases, allocate resources effectively, and design impactful public health policies and interventions.
Prevalence indicates the proportion of individuals in a population who have a specific disease or health...

Cancer

53.3K
Cancers arise due to mutations in genes involved in the regulation of cell division, which leads to unrestricted cell proliferation. Modern science and medicine have made great strides in the understanding and treatment of cancer, including eradicating cancer in some patients. However, there is still no cure for cancer. This is largely due to the fact that cancer is a large group of many diseases.

Mouse Models of Cancer Study02:43

Mouse Models of Cancer Study

6.3K
Mice have long served as models for studying human biology and pathology because of their phylogenetic and physiological similarity with humans. They are also easy to maintain and breed in the laboratory, and hence, many inbred strains are now available for research. Studies on mice have contributed immeasurably to our understanding of cancer biology.
The development of transgenic, knockout, and knock-in mice has led to an exponential increase in their use as model organisms in research,...

Summary

Colorectal cancer (CRC) incidence is rising in adults under 50, while declining in older adults. Addressing this trend requires improved screening and treatment access, especially for Alaska Natives.

Area of Science:

  • Oncology
  • Epidemiology
  • Public Health

Background:

  • Colorectal cancer (CRC) is a leading cause of cancer death in the U.S.
  • Recent data highlights shifts in CRC incidence and mortality across different age groups and demographics.
  • Understanding these trends is crucial for public health strategies and cancer prevention efforts.

Purpose of the Study:

  • To provide an updated analysis of colorectal cancer (CRC) occurrence in the United States.
  • To examine trends in CRC incidence and mortality based on age, race, and ethnicity.
  • To identify disparities and inform strategies for accelerating progress against CRC.

Main Methods:

  • Analysis of incidence data from population-based cancer registries (through 2016).
  • Analysis of mortality data from the National Center for Health Statistics (through 2017).
  • Examination of trends by age groups (younger than 50, 50-64, 65 and older) and demographic categories.

Main Results:

  • In 2020, an estimated 147,950 new CRC cases and 53,200 deaths are projected.
  • CRC incidence is increasing by approximately 2% annually in individuals younger than 50.
  • While CRC mortality is declining overall, rates are increasing in those younger than 50 and stable in American Indians/Alaska Natives.

Conclusions:

  • Despite overall declines, rising CRC incidence in younger adults necessitates further investigation into causes.
  • Disparities persist, with higher incidence rates in Black individuals and Alaska Natives.
  • Enhanced screening access and high-quality treatment are vital to accelerate progress against colorectal cancer, particularly in underserved populations.
