Lucy Davis makes her first public appearance since revealing she is living with incurable stage four breast cancer. In an emotional message shared during the appearance, the actress reflects on her life and career and calls for “more niceness in the world,” also encouraging people not to let others tell them they cannot do something.

Multiple outlets report that Davis is 53 and said she does not know how long she has left following the cancer announcement made earlier this month. Metro and other coverage place the appearance at a sci-fi convention on Saturday, while The Mirror frames the moment around her being in good spirits and sharing time with close colleagues, including Simon Pegg and Edgar Wright. The outlets largely agree on the themes of kindness and determination, with differing emphasis on her personal reflections and the specific setting of the event.
