World Cancer Day

World Cancer Day is on 4 February 2025.

We're raising awareness of the impact a cancer diagnosis can have on people's lives and highlighting the urgent need to provide better care for more people.

We're also sharing ways to get support, and how together we can help everyone affected by cancer.

A message to my younger self

Looking back can be powerful. In this heartfelt video, Nellie and Adil share a message to their younger selves before cancer. They reflect on the challenges they faced and the strengths they found.  

Whether you’re going through cancer yourself or supporting someone who is, their words offer reassurance, honesty, and hope.  

Wes Streeting ‘In conversation’ with Nick Robinson

This World Cancer Day we live-streamed a conversation between Wes Streeting, Secretary of State for Health and Social Care, and Nick Robinson, journalist and broadcaster.

This event was an exciting opportunity to bring members of the cancer community together to share their experiences ahead of the Government’s development of the Cancer Plan for England.

Watch a recording of the event.

Information about cancer

Cancer is when abnormal cells multiply and grow out of control. Over time, these cells can grow into a lump called a tumour. We have information to help understand what cancer is, how cancer starts and how we can help. See our information about cancer types, diagnostic tests, cancer treatments and drugs. 

If you need cancer information or support in your language, we have resources in other languages to help you. You can ask for some of our information to be translated into your language, or use our interpreter service on the Macmillan Support Line. 

You can also get information in other formats such as easy read and British Sign Language.
