Women with breast cancer have shown autonomic dysfunction evaluated by the Heart Rate Variability (HRV). However, there are few studies in the literature evaluating possible changes in long-term cardiac modulation in breast cancer survivor, in different postoperative periods, compared to individuals without the cancer diagnosis. The objective of this study was to investigate the relationship of the postoperative time of breast cancer on cardiac autonomic modulation and compare these values to those of women without cancer. It is a cross-sectional study consisting of 45 women aged 35-70 years, divided into post breast cancer groups (BCG1 and BCG2) and control group (CG). The BCG1 consisted of women after breast cancer surgery, with up to 18 months postoperatively and BCG2 with more than 18 months. The CG was composed of women without cancer. HRV indexes were used in the time domain, the frequency domain and geometric indices. The parasympathetic indices RMSSD, HF and SD1, and the SDNN index corresponding to sympathetic and parasympathetic modulation, in milliseconds, showed statistically significant reductions (p=0.0001) of BCG1 and BCG2 when compared GC. The LF values, which has a predominance of sympathetic tone, proved to be reduced in the cancer group, but statistically significant only when compared BCG2 and CG (p = 0.020)...
