McKenzie-Blu Kemish, four, from Southampton McKenzie-Blu also had a very rare genetic condition – the only reported case in the world – which destroyed his blood cells and caused kidney damage.
This caused serious complications with his chemotherapy treatment, so the medical team at the Southampton General Hospital had to operate to remove the tumour and then kill off any remaining cancerous cells with radiotherapy.
Amberley, who has five other children, said her 'miracle boy' came through the life-threatening surgery relatively unscathed. Now, her 'happy, cheeky little boy' is off treatment and at pre-school for one and half days per week.
She said her CLIC Sargent Social Worker was "amazing and provided us with so much help," including assisting with securing financial grants and benefits after both parents had to give up work to look after McKenzie-Blu and the other children.
Listen out for McKenzie-Blu's incredible story on Wave 105FM on Friday 26 April, as part of the CLIC Sargent Cash for Kids Appeal 2013.
