Sonja Hoy, BS, PGDip, of The Royal Marsden NHS Foundation Trust, London, UK, discusses the importance of good oral hygiene in cancer patients at the UK Oncology Forum (OF) 2018, held in Liverpool, UK. All cancer patients are entitled to good oral and dental care, particularly as most cancer treatments have side effects that affect the mouth. Unfortunately, this issue is often overlooked in the care pathway. The UK Oncology Nursing Society (UKONS) wants to promote oral hygiene as a priority of post-treatment care and educate patients on good oral hygiene throughout this difficult time.
