Oral mucositis induced by anticancer treatments is an inflammatory ulcerative condition of the oral cavity that arises as a side‑effect of chemotherapy, radiotherapy, or combined modalities. This complication compromises nutrition, quality of life, and can interrupt life‑saving cancer regimens, making its management a critical component of oncology care. The Oral Mucositis Induced by Anticancer Treatments market size was estimated at USD 2.1 billion in 2025, and the market forecast projects a CAGR of approximately 6.4% through 2033, driven by rising cancer incidence, expanding use of intensive chemo‑radiation protocols, and growing reimbursement for supportive‑care therapeutics. The growth outlook reflects heightened clinical awareness, increased adoption of prophylactic agents, and robust pipeline activity across biologics, topical agents, and analgesic formulations, underpinning a sustained industry expansion.
