Neo-RT

A Study Investigating Whether Changing the Sequence of Treatments (Starting Radiotherapy Followed by Hormone Therapy Before Surgery) is Feasible

Research summary

Four in 10 women diagnosed with breast cancer undergo mastectomy with or without breast reconstruction and less than half are satisfied with how they look unclothed. Breast conservation (removing the area with the lump only) can offer less extensive surgery and improved breast appearance, which can therefore increase well-being.

Intensity-modulated radiotherapy (IMRT) closely shapes the radiation beam to the cancer and is currently given after breast surgery. A new combination of IMRT followed by hormone treatment given before surgery, may increase the possibility of breast conservation.
