About the C50 Code Range
Malignant breast neoplasms are cancers that start in the breast or spread there from another site.
Under C50, most subdivisions identify where the cancer is in the breast. They distinguish the nipple and areola, central portion, upper and lower inner quadrants, upper and lower outer quadrants, and axillary tail. Other subdivisions identify overlapping sites (C50.8), an unspecified site (C50.9), or a malignant inflammatory neoplasm (C50.A).
