Sponsor: Mayo Clinic
Current Primary Outcome:
- Frequency of Breast Pain [ Time Frame: 4 weeks, 10 weeks ]Participants will complete a breast pain diary indicating the sensation of pain on a daily basis. The frequency of breast pain will be determined by the number of days per week that the subject recorded experiencing pain at 4 weeks and 10 weeks of each treatment.
- Severity of Breast Pain [ Time Frame: 4 weeks, 10 weeks ]Severity will measured using a 100 mm visual analog scale (VAS). The VAS does not have any pre-set marks between the extremes. For the pain severity VAS, 0 means no pain and 100 means extreme pain. The investigator measures the written mark of the participant in mm, and records this for the value of pain severity. The severity of breast pain will be determined by the mean of breast pain scores (determined for all days and for days for which pain is greater than 0) at 4 weeks and 10 weeks of each treatment.
Original Primary Outcome:
- Frequency of Breast Pain
- Severity of Breast Pain
Current Secondary Outcome: Mean Days of Pain During the 10 Week Treatment Periods [ Time Frame: Approximately 12 weeks and at 24 weeks after randomization ]
Original Secondary Outcome:
- Side effects
- Adherence
- Level of anxiety generated by breast symptoms
