Rachael said she was hoping to "leave an imprint of my love behind for the rest of [her son's] life". At the end, even though her body was at its weakest, her voice was at its strongest and most powerful.
After the heartbreaking phone call during which doctors told her that her cancer had metastasized, Bland wrote, "I scooped [Freddie] up and dashed home and then had to break [husband] Steve's heart with the news that my cancer was now metastatic and therefore incurable".
Recently, she garnered admiration for her positive approach to dealing with cancer, devoting herself to her acclaimed podcast, "You, Me and the Big C" as well as her supportive blog, "Big C little Me".

Her hugely popular podcast You, Me and the Big C also won awards for Rachael Bland and her co-presenters, Deborah James, a former deputy head teacher being treated for bowel cancer, and the lifestyle blogger Lauren Mahon, who had successfully completed treatment for breast cancer.
Tuesday, in a piece Rachael wrote before discovering her time was so cruelly limited, she shared her plans to prepare husband Steve and their three-year-old son Freddie, for the day when she would no longer be here.
Tony Livesey, Rachael's colleague and friend, said: "5 live's lost one of its brightest spirits".

"You'll never know how much those messages meant to her and us. Her legacy is a testament to how much more we need to do to beat this awful disease". Bright, funny, feisty. She allowed us to have a frank conversation about cancer with those closest to us.
She said: "I have to suppress a lot of the darkest thoughts about Freddie growing up without his mummy around". I listened to one of Rachel's podcasts this week and was amazed at how charming, amusing and gracious she was in the face of such tragic circumstances. She married her colleague Steve Bland in 2013. "Our sympathies go out to her family and many friends at this hard time". I will get through this for you Freddie.
BBC weather presenter Simon King, responded to her husband Steve: "Devastating news Steve, I'm so so sorry". She has also put together a collection of handwritten notebooks, perfume, and other personal items for Freddie.More news: Tropical Storm Gordon forms near Florida Keys
