Brief summary
Accelerated Partial Breast Irradiation by Mammosite and intensity modulated radiotherapy is safe and effective in patients with early stage breast cancer resected by lumpectomy.
Interventions
Treatment will be performed using high dose rate brachytherapy, starting between 2-5 days of implant, 34 Gy at 1 cm in 3.4 Gy fractions BID for 5 treatment days with typical boost dose od 10 Gy given in 2 fractions at least 6 hours apart.
