Donna McWhinnie, 26, had no idea she had the glioma tumour - which had been growing for 10 years - until she had a seizure.
As previously reported in the Evening Times, Donna was shocked at the discovery having suffered no previous symptoms.
At 10cm by 5cm it was half the size of her brain.
After undergoing radiotherapy at the Beatson Cancer Centre to bring the noncancerous growth under control, the hairdresser from Coltness, just outside Wishaw in North Lanarkshire, selflessly decided to dedicate her time to helping others.
Donna, who is mum to 21-month-old son Taylor, has amazed her friends and family with her resolve in the face of serious illness and gruelling treatment.
She organised an action-packed fundraising night in Wishaw recently and hundreds of friends and family members turned up to support her.
Donna said: "It was a great night and I would like to thank everyone who donated so generously.
"We raised £3000 for the Beatson and £3000 for Brain Tumour Research.
"My target was £5000 so I am really pleased that I managed to raise so much.
"This has made me want to organise more charity events."
Soon after the charity night, Donna was given some more good news when a scan revealed her tumour had not increased in size and the pressure in her head had reduced.
She said: "The tumour was never going to get any smaller but it is good to know that the pressure is away.
"The doctors told me that they are really surprised that I wasn't crippled with headaches because of the pressure in my brain.
"There is a chance that it will grow again in the future and I will need chemotherapy but for now I just have to monitor my symptoms and go for regular checkups. At the moment I feel fine."
Donna's positivity has amazed her proud family and mum Lesley McWhinnie said of her daughter: "Nobody could fill Donna's shoes - I don't know where she gets the strength."
Donna said she is determined to live her life to the full and spend as much time as possible with her son.
She has given up her her salon Deezignz in Wishaw but it will remain open.
Donna added: "Things have been put into perspective for me and that is why I decided to give up the shop.
"Life is too short and I want to spend as much time as I can with Taylor.
"But I will be back and I will be back with a bang."
