October is almost over and our Big Letter Write has had you joining together in your community groups to write letters.
And those groups have been all over the world - from Cayman Islands to Australia and Brighton to Liverpool.
Almost 60 School groups, church groups, friends, work colleagues and families have been writing letters, making cards and sharing ideas.
Some groups have produced over 90 letters while others just a few but all written with the same kindness and generosity.
And so far we have received well over 370 letters, lots and lots of stamps and some donations too.
But the Big Letter Write isn't done yet. Not had time to get your group together yet? Well, get them together in the next couple of weeks and send your letters and fundraising to us and we'll add them to the final total. Our target was 500 letters so we can definitely get there - changing the day of 500 people going through cancer treatment.
Please keep posting your pictures on social media #BigLetterWrite and sharing your stories.
A huge thank you to everyone who has taken part, including Basildon Bond, BBC Sussex, BBC Surrey, Blake Envelopes, Postal Museum, Brighton Jubilee Library and Jarrovian Wealth.
