Study Notes

Factors Contributing to Cancer Risk

Multiple factors can contribute to cancer risk, including environmental risk factors and acquired conditions.

Environmental Risk Factors for Cancer

Established environmental risk factors for cancer include radiation, certain chemicals, and UV radiation.

Age and Cancer Risk

Adults older than 55 are most likely to develop carcinomas, likely due to the accumulation of genetic mutations over time.
The risk of cancer increases with age, particularly after age 55.

Acquired Conditions and Cancer Risk

Acquired conditions, such as chronic inflammatory diseases, can increase the risk of cancer.
Chronic inflammatory diseases increase the risk of cancer due to the production of reactive oxygen species (ROS) and chronic DNA damage.

Cancer Risk and Immunodeficiency

Immunodeficient patients are at an increased risk for cancer due to their inability to combat cancer cells effectively.

Cellular Changes and Cancer Risk

Metaplasia is the process by which one differentiated somatic cell is replaced with another.
Dysplasia is an example of localized morphologic changes in epithelial tissue that increase the risk of malignant transformation.
Hyperplasia is the term for the increase in the number of normal cells in a tissue.

Cellular Response to Inflammation

Chronic inflammatory diseases can lead to tissue damage, which is repaired through cellular processes.
Activated immune cells can produce reactive oxygen species (ROS), which can damage DNA and lead to carcinogenesis.
Inflammatory mediators produced by immune cells can promote cellular proliferation, preventing apoptosis and increasing the risk of cancer.

Cancer Hallmarks

The Warburg effect is a hallmark of cancer, where malignant cells exhibit altered metabolic activity.
Another hallmark of cancer is the ability to evade apoptosis.
"Robbins and Cotran Pathologic Basis of Disease" is a reference book for pathology concepts.

Other Concepts

Cancer risk is not increased by coffee consumption, which is NOT an established environmental risk factor for cancer.
