From Me to You is hosting 'From Me to Brew' which gives people the chance to host events and raise cash to get more letters sent to Worcester Breast Unit Haven and other sites.
It aims at inspiring people to write letters and create connections to bring comfort to people who are going through cancer.
Alison Hitchcock, Co-Founder of From Me to You said: "We're very excited by our latest campaign as it is such an enjoyable way to get people together and ensure that no one has to face cancer alone.
"Whether people would like to host their From Me to Brew gatherings at home, take over the staff room at work or have a stall outside a local school, every single event will make a huge difference to our work and allow us to get more letters to more people.
"Every year we send over 10,000 letters to cancer patients - helping to ease the loneliness and isolation they can experience during treatment and recovery.
"To some, our letters bring a welcomed distraction from cancer.
"To others they are a lifeline. From Me to Brew is another way to help keep people with cancer connected, one cuppa, cake or biscuit at a time."
Organisers who raise over £200 from their From Me to Brew event will also be entered into a prize draw to win a writing set from The Wildflower Illustrations Company.
