Race and Cancer Genetics: Lessons From BRCA1
January 01, 2002
The study of cancer in specific populations can offer clues useful in determining the extrinsic and intrinsic factors influencing cancer in all populations. Extrinsic factors are sometimes called "environmental" in the broadest sense of the word. They are modifiable or mutable. Intrinsic factors are more inherent to the individual. They are almost always genetic and are immutable or unchangeable. Targeting research on specific populations is and should be a significant ethical issue.
