«Currently, approximately 1 in 5 women who undergo breast - conserving surgery, also known as
lumpectomy, require repeat surgery due to inadequate excision of the tumor during the initial
surgical procedure,» explains Arnie D. Purushotham, MD, professor at King's College London, UK.
A new study by UCLA scientists has found that women diagnosed with breast cancer and treated with a one - week regimen of partial breast radiation after the
surgical removal of the tumor, or
lumpectomy, saw no increase in cancer recurrence or difference in cosmetic outcomes compared to women who received radiation of the entire breast for a period of up to six weeks after surgery.
