The Effect of Education Given on Preventing Mouth Ulcers in Women With Breast Cancer

The intervention group was trained on the use of the Oral Mucositis Prevention Patient Education Handbook, which was prepared by the researchers based on literature information and expert opinions. Participants in the intervention group received telephone consultations on days 7 and 14. The control group continued to receive routine nursing care. The second interview was completed on day 21, when both the intervention and control group patients returned for their next treatment cycle, using the WHO Oral Toxicity Criteria, ADR, and EORTC QLQ-C30 Version 3.0 Quality of Life Scale.
