Objective: to investigate the incidence of invasive breast cancer (IBC) in pre- and postmenopausal women treated with T therapy and T in combination with E (T/E)
2,377 pre- and post-menopausal women were treated with T or T/E implants.
Total cases divided by the total sample size and years in study was expressed as an incidence per 100,000 person-years.
The BC incidence was compared with age-specific Surveillance Epidemiology and End Results (SEER) incidence rates.
Conclusions: T and/or T/E pellet implants significantly reduced the incidence of breast cancer in pre- and post-menopausal women. The addition of E did not increase the incidence over using T alone.

Objective: to investigate the incidence of IBC in pre- and postmenopausal women (presenting with symptoms of androgen deficiency) treated with subcutaneous testosterone implants or testosterone implants combined with anastrozole.
10-year prospective cohort study
Incidence rates on testosterone therapy were compared to age-specific Surveillance Epidemiology and End Results (SEER) incidence rates and historical controls.
Conclusions: Long-term therapy with subcutaneous testosterone, or testosterone combined with anastrozole, did not increase the incidence of invasive breast cancer.
