Iranian researchers succeeded in early diagnosis of breast cancer through designing a computer-Aided Detection (CAD) system to conduct sievev mammography and examine computerized images of the mammography.

Dr. Nader Riahi Alam, specialist in medical physics who has designed the system, told ISNA, "Our studies focus on designing a test CAD system to examine mammography images digitally used for the first time in Iran."

He said mammography is the best method to detect breast cancer, adding that the old method's error is some 10-20 percent.

Using CAD, the image is analyzed by software which lessens errors, he said adding only 15-30 percent of the biopsies are malignant, whereas biopsy id risky for the patient.

The doctors can examine abnormality by using the CAD, he added.

The system can be used in hospitals, policlinics, research centers, technical mammography centers and clinics.

Breast cancer (malignant breast neoplasm) is a type of cancer originating from breast tissue, most commonly from the inner lining of milk ducts or the lobules that supply the ducts with milk.

Cancers originating from ducts are known as ductal carcinomas; those originating from lobules are known as lobular carcinomas. Breast cancer is a disease of humans and othermammals; while the overwhelming majority of cases in humans are women, men can sometimes also develop breast cancer.

The size, stage, rate of growth, and other characteristics of the tumor determine the kinds of treatment. Treatment may include surgery, drugs (hormonal therapy and chemotherapy), radiation and immunotherapy.

Surgical removal of the tumor provides the single largest benefit, with surgery alone being capable of producing a cure in many cases. To somewhat increase the likelihood of long-term disease-free survival, several chemotherapy regimens are commonly given in addition to surgery.
