What is the meaning of hem marker?

Hem marker: A person who carries certain genetic markers associated with a higher risk of developing a blood-related cancer, such as leukemia, lymphoma, or myeloma. These genetic markers may indicate a predisposition or susceptibility to these types of cancers, but it does not necessarily mean that the individual will develop the disease. Hematologists and geneticists use this information to identify and monitor individuals who may be at higher risk for developing blood cancers, allowing for closer surveillance and early intervention if needed.
