Clinical Trial Summary

When we talk about early identification, we are talking about an ALREADY EXISTING INJURY, triggering a change in the patient's quality of life and a projection of future costs for the health system.

INNOVATIVE ASPECT: While screening mammography identifies an existing lesion, VTM could: Make an early diagnosis before the formation of a visible or palpable tumor mass; Check the metabolic activity in suspicious lesions identified by other diagnostic methods; Demarcate tumor range and tumor similarity from a distance in breast cancer.

Regarding the Risk x Benefit:There are no medications incorporated, associated or administered by the equipment; There is no ionizing radiation incorporated or delivered by the equipment; There are no contraindications for the use of the equipment by the patient (Non-ionizing infrared radiation, without contrast or contact); Audience destined to operate the equipment: Physician / Radiologist with training Therefore, the research in question is of great relevance for such a debilitating health problem for the patient and for the health system.

Description:

Breast cancer control has been one of the priorities on the agenda of the National Health Policy in Brazil. Thus, the Ministry of Health, through the publication "Guidelines for the Early Detection of Breast Cancer in Brazil", recommends the identification of the disease in its early stages through early detection strategies. It is estimated that there will be 66,280 new cases of breast cancer for each year of the three-year period 2020-2022 in Brazil and Population-Based Cancer Registries (RCBP), Hospital Cancer Registries (RHC) and information on Mortality are essential requirements for national and regional programs for cancer control, in addition to guiding the research agenda.

According to the National Cancer Institute (INCA), the benefit of screening mammography is in early identification, allowing for less aggressive treatment.

VTM is a functional method that demonstrates the metabolic intensity in real time, through images in the colors of the visible spectrum without using ionizing energy or contrast. It expresses metabolic alterations before anatomical transformations. It is a method without radiation, contrast, pain or contact, and can be used without limiting the exposure time.
