Abstract
BACKGROUND: Cancer during pregnancy is a rare event. However, knowledge about treatment has progressed in recent years with improved maternal and neonatal outcomes. The number of women who decide to continue their pregnancy and undergo cancer treatment is increasing. MAIN BODY: Women face two critical events simultaneously; oncological illness and pregnancy, with different and conflicting emotions. In addition, the last trimester of gestation sets the ground for construction of the mother-child relationship, which is of great importance for the child's development. Studies have showed that maternal exposure to stressful events during pregnancy is linked to adverse outcomes in children. Although several authors consider cancer to be a 'critical life event', studies that address the psychosocial implications of cancer in expecting mothers are scarce. There are no studies addressing the possible negative impact of a cancer diagnosis during pregnancy on the mother-child relationship and on the child's development. It is important to emphasize the need for in-depth knowledge of the contributing psychological factors involved in order to provide holistic, individualised, and supportive care. CONCLUSION: An analysis of cognitive aspects, emotional processes, and maternal attachment in cases of cancer during pregnancy may contribute to the development of a model of care, both in an evolutionary and in a psycho-oncology context, with implications for clinical practice.
