NCI patient treatment article for this disease Exact source article; not a clinically reviewed indication or current-standard recommendation.
With this type of radiation therapy, an x-ray machine delivers radiation to either the whole breast, or, if done after mastectomy, to the entire chest wall. Sometimes, radiation will also target the lymph nodes in the armpit or neck area or under the breastbone. Most people have treatment once a day, Monday through Friday, for about 5 to 6 weeks. In some cases, it may be done in 4 weeks or less. Your doctor will recommend the treatment regimen that is right for you.
