This study aimed to describe the experiences of chemotherapy-induced oral mucositis among patients with breast cancer. Its primary focus is on how chemotherapy-induced oral mucositis affects day-to-day functioning, psychological wellness and overall quality of life.

12 Jordanian women who had been diagnosed with breast cancer and had presented with chemotherapy-induced oral mucositis were the purposive sample for this qualitative study, which employed in-depth, semistructured interviews. The verbatim transcriptions of the interviews were subjected to thematic analysis.

The thematic analysis of the 12 participants’ reviews revealed five main themes: distressing physical manifestations, eating and nutritional struggles, mouth care difficulties, psychological strain, social and emotional consequences, and coping and adaptation strategies.

Breast cancer patients’ daily routines, mental health and quality of life are all significantly impacted by chemotherapy-induced oral mucositis. According to the study, individuals with breast cancer who experience chemotherapy-induced oral mucositis should get patient-centred care and address their emotional, psychological, social and physical discomfort to maximise their outcomes.
