Abstract
The article had been built the model to determine the carcinoma and benign types. Potentially, the physical quantities could be differ of each them. The biopsy methods had developed in classifying the
both carcinoma and benign types. In this research, the probability of gray-level pairs on certain distance are derived from the mathematical model of the mammography physical quantities are used.
In the previous research, determination of infiltrating ductal carcinoma and infiltrating lobuler carcinomahistopathology types, breast cancer stadium, health level of contra lateral,andreadability
increasing x-ray mammography images on histopathology types determination on breast cancer using special patern cropping are succeeded. In this research, the mathematical model of the mammography
physical quantities is succeeded to determine the carcinoma and benign histopathology types. The model had been proposed for testing 120 the new patients mammogram at Dokter Soetomo Hospital,
Surabaya, Indonesia. The research results showed the physical quantities could be predict the carcinoma and benign histopathology types in 86,67 sensitivity for 2 x 2 cm sample sized and
α = 5 .
Keywords : mammography, ca mammae, carcinoma, benign.
1. Introduction
The following methods of the breast cancer early detection had been patented are employing histogram peak detection [1], histogram alteration [2], pixel mapping [3], neural network [4], contour [5], wavelet
filter dan artificial neural networks [6], minimally invasive diagnosis and treatment [7], morphological closing [8], histological analysis [9], blood vessel walls [10], but all the above methods detect the

presence of microcalcification only, but determination of the type of carcinoma and benign breast cancer are not supported.The classifying types of Infiltrating Duktal Carcinoma and Infiltrating
Lobuler Carcinoma breast cancer histopathology using physical parameter in86,36 sensitivityin previous research are succeeded [11]. The determination of the level of the contra lateral breast health
using physical parameters in 93.75 sensitivity [12], the breast cancer stadium state in 86.67 sensitivity of [13]. Also, the readibility x-rays results of mammography on breast cancer
histopathological type determination using a special pattern croping through physical parameters in 97.5 sensitivity are succeeded too [14].
This paper organized as follows, section 2 discussing the radiation intensity on ca mammae, section 3 about physical quantities of the result of X-ray mammography images, the probability function in
section 4, section 5 about the multinomial linear regression function as an outcome types of carcinoma and benign, results and discussion in section 6 and the last section are conclusions.
2. The Radiation Intensity on Ca Mammae
Increase of the radiation absorption intensity depends on breast cancer density increasing due to pixel intensity values of carcinoma and benign types are different. So that the physical parameters between
the types of carcinoma and benign are different. The transmittance of the X-ray radiation intensity are written in equation 2.1 bellow [11][12][13][14].
