Mummy's Lump is the UK's first-ever book to help young children whose mums have been diagnosed with breast cancer.

Author Gillian Forrest, Consultant Child Psychiatrist and Senior Research Fellow at Oxford University, who was diagnosed with breast cancer in 1990 when her children were five and seven, said: "Even though I am an experienced child psychiatrist, I was very unsure how to talk to my children about my diagnosis. Nobody asked if I had any problems with explaining what was happening to my children, everything was focused on my condition." 

To help other parents facing the problem Gillian decided to write a book aimed at the under-sixes, which would explain what their mum was going through. 

Mummy's Lump follows Elly and Jack as they learn of their mother's diagnosis and treatment for breast cancer. It has the look and feel of a classic children's story book, with illustrations by Sarah Garson and a read-along narration by Zoë Wanamaker.
