National Mammography Day in Brazil
Posted on: 2021-02-05
National Mammography Day is celebrated on February 5 in Brazil; the date aims to alert about the importance of the exam to detect breast cancer. Besides, the test is the most effective for detecting the disease. Publications in the national radiological literature are a reason for reflections and studies on breast assessment using imaging methods. Thinking about it, how did mammography and mammography come about?
Development over the years
Radiographs of breast lesions begin to be taken about 18 years after the appearance of x-rays in 1923 by the German surgeon Albert Salomon. He published his monograph on the usefulness of radiological studies of mastectomy specimens. Thus, there was a demonstration of the possibility of anatomic-radiological and pathological correlation of breast diseases, classifying them into benign and malignant conditions. He found small spots in mastectomy surgeries and called them “microcalcifications”.
The pioneer in improving image quality was Raul Leborgne, who drew attention to the need for technical qualification for the positioning and radiological parameters used.
In 1950, pathologist Helen Ingleby included evaluating the breast and its variations according to the age and menstrual status of the patients, also taking into account the micro and macroscopic radiological correlation with the sectional histological sectioning technique of the breast.
Machine dedicated to mammography
Despite these advances, the first machine dedicated to mammography was launched in 1966, causing several companies’ manufacturing wave. In 1977, a new model with x-ray tubes appeared. And the second generation of this model appeared in 1980.
In Brazil, mammography is associated with the Brazilian Institute of Cancer Control (IBCC), as it was responsible for bringing the first mammograph to the country in 1971.
Today, we know that it was a vast mastological achievement for the country and, since then, the incentive to mammography has only grown. It is necessary to detect the disease early for a more effective fight. The Ministry of Health of Brazil and the World Health Organization recommendation is that screening mammography be performed on women aged 50 to 69 years once every two years, before the onset of symptoms.
