OBJECTIVE: To investigate the clinicopathological findings of women diagnosed with breast cancer and study the impact of chronic psychological stress on the pathological characteristics of these tumors.
METHODS: We investigated a cohort composed of women diagnosed with breast cancer and divided into two groups. One group was categorized as presenting with chronic psychological stress (by using the Self-Reporting Questionnaire - SRQ-20). Another group of women with breast cancer, but with no previous history of chronic psychological stress, comprised the Control Group. Clinical and pathological data were assessed.
RESULTS: Women presenting with a history of chronic distress were significantly overweight when compared to the Control Group. Furthermore, it was observed that these stressed women also had a significant percentage of aggressive breast cancer subtype, the HER2 amplified tumor, which could be putatively associated with the loss of immunosurveillance.
CONCLUSION: Our findings suggested an interaction among chronic psychological stress, overweight, and the development of more aggressive breast tumors.
