A genetic test that could determine men at the highest risk of developing aggressive disease could change how prostate cancer is treated, he says, since doctors would be able to more accurately predict which men would need more rigorous follow-up and which men likely wonât have to worry about their prostate that much.
In genetics, a biomarker (identified as genetic marker) is a DNA sequence that causes disease or is associated with susceptibility to disease. They can be used to create genetic maps of whatever organism is being studied.ne example of a commonly used biomarker in medicine is prostate-specific antigen (PSA). This marker can be measured as a proxy of prostate size with rapid changes potentially indicating cancer.
