If she makes it to her 40th birthday, Kim will be among the longest-surviving 10% of people diagnosed with her type of cancer.
She said this has led to her treasuring every moment with her sons.
“I don’t know if I’ll see them start school,” she said.
“You take those little moments for granted until you realise they could be taken away.
“My diagnosis has given me the clarity to enjoy every moment I have with my boys.”
She added: “I know I would have made a bloody good granny.”
Kim said her experience had also brought home the lack of attention and resource given to tackling brain cancer, where survival rates in the UK have not changed for decades.
She said this felt like an “injustice” given that survival rates for many other cancers had improved “dramatically” over the same period.
She has joined the Brain Cancer Justice (BCJ) campaign group, which is urging politicians to provide greater support and funding for rare cancers.
The group is also calling for a dedicated minister for rare cancers to ensure continuity in research, funding and policy.
