London Global Cancer Week (LGCW) 2026, coordinated by the London Global Cancer Week initiative, will take place on 2–6 November 2026 across London, United Kingdom.

Rather than a single conference, LGCW is a city-wide programme of independently hosted events bringing together clinicians, researchers, academics, policymakers, health-system leaders, patient advocates, civil society organisations, industry partners, and global health networks to address inequities in cancer prevention, diagnosis, treatment, survivorship, and health-system capacity. Participating organisations may host in-person, virtual, or hybrid events, including scientific symposia, policy roundtables, community discussions, and workforce-development sessions.

The initiative focuses on highlighting disparities in cancer outcomes, sharing evidence-based and scalable solutions, strengthening international collaboration, and encouraging practical action to improve equitable access to cancer care worldwide. London Global Cancer Week grew from annual global oncology meetings initiated by the Royal Society of Medicine Oncology Section in 2016 and developed into a week-long programme in 2019.
