Post-lumpectomy radiation therapy
Radiation therapy is performed in breast cancer to destroy any trace of cancer cells that may be left after lumpectomy. It reduces the rate of recurrence in 75% of patients, and it is considered a standard of therapy in every stage of the disease, even in low-grade breast cancer, and even if the patient has the best prognosis. There are two types of post-lumpectomy radiation therapy: partial breast radiation and whole breast radiation, and the dosage is also variable, usually administered for 5 days. However, in some cases of low-grade cancer, a single dose of radiotherapy might be the best option after lumpectomy.
