About the C57 Code Range
These cancers affect female genital organs, including the fallopian tube, broad ligament, round ligament, parametrium, and uterine adnexa.
The subdivisions separate cancers by site. The fallopian tube (C57.0), broad ligament (C57.1), and round ligament (C57.2) each split into right, left, and unspecified sides. Other subdivisions identify the parametrium, unspecified uterine adnexa, other specified organs, overlapping sites, or an unspecified female genital organ.
