Outcome Measures

Primary Outcomes (1)

  • The reproducibility of breast shape through cross-correlation values, both with and without the use of a bra

    Evaluating the reproducibility of breast shape through cross-correlation values in cone-beam CT and planning CT matching. This study involves comparing groups of patients wearing and not wearing a bra

    During the radiotherapy, an average of 1 month

Secondary Outcomes (3)

  • Radiation dosimetric evaluation

    at the time of completion of radiotherapy

  • Patient satisfaction assessment

    at the time of completion of radiotherapy

  • Assessment of treatment toxicity

    at 6 months and 12 months after the radiotherapy

Study Arms (2)

Group wearing a bra

EXPERIMENTAL

Patients wear a bra while receiving radiotherapy.

Device: Group wearing a radiotherapy bra

Group not wearing a bra

NO INTERVENTION

Patients do not wear a bra while receiving radiotherapy.

Interventions

Group wearing a radiotherapy bra

Group wearing a bra
