In our study population there were 227 females and 64 males, and the mean study patient age was 50 years (range 20–83 years). There were 79 of 225 females (35%) who had a cancer, as diagnosed by histopathology. The mean age for females was 50 years (range 20–83 years), and for males was also 50 years (range 23–80 years). The rate of malignancy for each BSRTC category in females was; 14.2%, 3.2 %, 26.4 %, 19.5 %, 81.3% and 100% for non-diagnostic, benign, AUS/FLUS, sFN, sM, and malignant diagnoses, respectively (Table 2). There were 34 of 64 males (53.1%) who had a cancer diagnosed by postoperative histopathology. The rate of malignancy for each BSRTC diagnostic category in males was 0%, 7.7%, 25%, 46.2%, 66.7% and 95% for non-diagnostic, benign, AUS/FLUS, sFN, sM and malignant diagnoses, respectively (Table 2). Even though thyroid cancer was significantly more common in males (p=0.021), gender did not significantly influence specific BRSTC diagnostic category cancer risk estimation (Table 2).
