Who may be able to join

AI generated eligibility summary. Written by an AI model from the official source data and checked on a sample basis. It can contain mistakes, so confirm anything important against the original source. How we use AI

Who might be able to join this trial:

  • Participants must have provided documented informed consent (themselves or through a legally authorized representative)
  • Participants must be aged 40 years or older
  • Participants must be female
  • Participants must be able to read and understand English to complete study questionnaires
  • Participants must have a confirmed breast cancer diagnosis based on tissue testing
  • The breast cancer must be of the epithelial type (certain rarer types, such as lymphoma or sarcoma of the breast, are not included)
  • Participants must have had breast-conserving surgery (lumpectomy), including cases where a second surgery was done to achieve clear margins
  • Participants must have had a surgical procedure to check the lymph nodes under the arm (either a sentinel node biopsy or a full lymph node removal)
  • Participants must have at least one high-risk feature that would lead their radiation oncologist to recommend a boost dose of radiation to the lumpectomy area
  • A doctor must have rated the cosmetic outcome after lumpectomy as "Good" or "Excellent" using a standard four-point scale, assessed before radiation treatment begins
  • Participants of childbearing potential must have a negative pregnancy test (urine or blood) before joining (confirm with trial site for exact definition used)

Who may not be able to join:

  • People who have had prior radiation treatment to the affected breast area in a way that, in the investigator's opinion, would prevent further breast radiation
  • People whose cancer has spread to nearby lymph nodes in a way that requires a broader type of radiation treatment covering the collarbone area
  • People with a serious uncontrolled medical condition
  • People with stage IV (advanced/metastatic) breast cancer
  • People diagnosed with Paget's disease of the nipple
  • People with another current or previous cancer, unless that cancer is unlikely to affect the safety or results of this trial (the trial site would assess this on a case-by-case basis)
  • People who are pregnant or breastfeeding
  • People who, in the investigator's opinion, may not be able to follow all study procedures and requirements
