Actress Lucy Davis has revealed she is living with incurable stage 4 breast cancer that began as a symptom so small she almost didn't get it checked out.
Why it matters
Davis's case is a direct warning about small, easy-to-dismiss breast changes; she says she nearly ignored a spot because it didn't match the lump she expected to feel.
What to watch
Davis says she is choosing to focus on joy and purpose during treatment, and is urging others: 'don't ignore anything, get everything checked out.'
