Writing on his Twitter account, @arkangel2605, John says:
"I start chemo 2moro--I urge everyone to be checked for cancer regularly, ’cause cancer growth is rapid--and before you know it--agonising."
This announcement itself follows John’s surgery in May this year where a malignant tumour was removed.
Please send John your good wishes via his management at jw@qedg.co.uk.
