Mammography is the main method of visualizing the mammary glands for the diagnosis of pathologies. This method allows you to analyze any changes in the breast, for example, the visible symptoms of breast cancer are the entrained nipple, the accumulation of single microcalcinates, vascularization around the tumor, the shape of the tumor with indistinct, uneven edges, a spicule-shaped contour. To standardize the analysis of results by scientists from the American College of Radiology, a BI-RADS system was developed. One of the classifications of neoplasms in this system is their form. In the work the technology of recognition of new formations of a mammary gland of three basic types is offered: a cyst, a fibroadenoma and a cancer, based on the analysis of their form. The aim of the work is to find the basic geometric characteristics of the new formations (area, perimeter, shape factor, convex hull surface, convex hull form factor), classification of neoplasms based on analysis of their shape. The obtained results of experimental research have shown the opportunity to use the given algorithm in mammographic screening.

Key words: mammogram, mammary gland cyst, fibroadenoma, breast cancer, recognition, geometric features, BI-RADS, form, convex hull.
