The necessity to include the internal mammary nodes (IMNs) during breast and nodal irradiation for every patient remains under discussion, particularly for early-stage breast cancers. The dosimetric effect on nearby musculoskeletal (MSK) structures when targeting the IMNs remains to be completely understood; hence the focus of this current study.&lt;/div&gt;&lt;/div&gt;&lt;div&gt;&lt;h3&gt;Methods&lt;/h3&gt;&lt;div&gt;This retrospective study included breast cancer patients who underwent lumpectomy and nodal sampling followed by adjuvant hypofractionated whole breast and regional nodal RT (4005 cGy in 15 fractions) who were treated between January 1, 2022, and November 30, 2023 at a single institution. MSK structures such as the bones (ribs, scapula), muscles (pectoralis, rhomboids), and joints (glenohumeral, acromioclavicular) were retrospectively contoured on the CT simulation images. Two RT plans (one with and one without IMN coverage) were created, and dosimetric parameters including mean (Dmean), near maximum (D2), near minimum (D98) and volumes received 15, 20 and 40 Gy (V15, V20, V40) were compared. Standardized mean difference between the plans was calculated for each dosimetric parameter, and Wilxocon’s signed-rank test was used for comparison. Univariable linear regression analysis was used to identify patient and tumor factors that were associated with more significant dosimetric differences.&lt;/div&gt;&lt;/div&gt;&lt;div&gt;&lt;h3&gt;Results&lt;/h3&gt;&lt;div&gt;A total of 30 breast cancer patients with a median age of 63 (range 30–82 years) were selected for analysis.
