Are the treatment options safe?
Treating the cancer with endocrine therapy before surgery is safe. It is recommended as an approach to consider in national and international health care guidelines.
Your endocrine therapy treatment starts the day you join the study and your tumour will be monitored closely both at the hospital and with scans.
Endocrine therapy is very effective for oestrogen sensitive breast cancer. You would also not be offered this research if we did not think the treatment options were good and safe.
However, during the close monitoring, the clinical team will always be able to schedule your surgery early if medically required.
