No one should have to face cancer alone.
Macmillan Cancer Support wants to make sure no one has to face cancer alone. A cancer diagnosis can change everything, so we're here to help you with anything from money worries to advice about work, healthcare options to just needing someone to talk to. We're a constant source of support to people affected by cancer and their families and carers.
As treatments improve, more and more people are living with cancer in their daily lives. We fund specialist health care professionals and build cancer care centres to help provide cutting edge support.
We rely completely on our supporters to help us make sure that people facing the toughest fight of their lives don't have to do it alone.
