A registry is an observation database. Participation in this registry does not require any additional or different procedures or drugs other than those you would normally receive for breast cancer. Registry databases are used to identify trends in medical care that help the medical community identify optimal care for different diseases.

The data will be compiled on the safety and performance of the Partial Breast Brachytherapy Applicator based on the information collected about the treatment and follow up visits.

PURPOSE OF STUDY

The patient understand that she has cancer of the breast. The patient understand that is offered the opportunity to participate in a registry study to collect data on the FDA approved device,Partial Breast Brachytherapy Applicator. Partial Breast Brachytherapy is a treatment method that works by delivering radiation from inside the breast directly to the tissue where cancer is most likely to recur. The Partial Breast Brachytherapy Applicator is a device that has tiny catheters or wires that fit inside the lumpectomy cavity (the space left after the tumor is removed). Radioactive sources (seed) are placed within the device by a computer controlled machine. This radioactive source will deliver the radiation therapy to the breast
