INTRODUCTION: Breast milk is a great source of nutrients for the baby's immunological and psychological development, and has a strong impact on infant mortality. It all starts in the thirty-second week of gestation, as this is the time when the fetus begins to show sucking reflexes. The breastfeeding process can be very difficult, since if there is no monitoring, there may be cracks in the breasts, making the process very painful. METHODS: This is a descriptive and qualitative study, which took place in person and virtually in the city of Porto Velho/RO at the Physiotherapy School Clinic of the São Lucas University Center, with the objective of hearing reports from women/mothers who are or have been exclusively breastfeeding. Thirty-eight female women, aged 20 years and older, were selected to report their breastfeeding process as lactating women. RESULTS AND DISCUSSION: One of the reasons for this development is the incorrect breastfeeding process. The main risk factors identified were: the baby's latch on to the mother's breast, where there is incompatibility between mother and child, primary and race/color of the mother defined as white or yellow. Many lactating women end up thinking that all they have to do is let the baby latch on to the breast and perform the suction, since even the positioning of the child interferes in the process. It was also evident in the interviews that most of the women did not perform the procedure due to lack of knowledge, often not being instructed by the health professional, or for fear of the effects of the procedure, since most of the women interviewed are very young and from lower social classes, they end up having this transgression of low performance of the procedure. CONCLUSION: Laser therapy has been shown to be an effective and safe intervention in the treatment of breast fissures, a common complication during breastfeeding that can cause intense pain and difficulties in breastfeeding. By using low-level laser therapy, it is possible to promote healing of injured tissues, relieve pain and reduce inflammation, providing greater comfort to mothers and encouraging continued breastfeeding. The importance of this treatment lies in its rapid and non-invasive effect, offering an alternative to traditional therapies, such as ointments and dressings, which often do not provide immediate or complete relief. In addition, laser therapy helps to prevent early weaning, contributing to the well-being of the baby and the mother, since exclusive breastfeeding is essential in the first months of life.
