in the cynon valley, christopher mugford joins the local choir rehearsal. together. for months, he's been worried he may have bowel cancer after showing symptoms. injanuary, he was told he'd need further tests. a date in march was set for the colonoscopy but lockdown meant non—emergency operations were cancelled. i think it's 30, 31 weeks beyond the date that i was supposed to have surgery. and if it's a cancer inside me, it's progressing. my concern is notjust for myself, there were 25 or 30 people in that room, waiting to see a colorectal surgeon. i'm lucky knowing about it, i went to my gp straight away. if any of those people had waited, they could be in an advanced stage of having cancer and not getting treatment and none of them know. as christopher waits for his tests, he's not alone. during the first lockdown, it's feared thousands of others waited longer for their tests too. this cancer hospital in cardiff sees around 5,000 new cases a year, but in lockdown fewer emerged. there are some thousands of patients who have not come through to the system
