Human population cytogenetic studies have revealed that a majority of persons who are prone to developing malignant features possess chromatin bodies termed as marker dots (MDs) measuring nearly 2 to 3 microns. These MDs are seen emanating from certain specific chromosomes, which may be early indicators of neoplastic transformation within cells.
