Russell Brand's mother has breast cancer.

The 38-year-old comedian has cancelled his show at Derby's Assembly Rooms in the East Midlands tonight (07.03.14), so he could be with Barbara after it emerged she is battling the disease.

He also pulled out of a show in Glasgow recently citing ''family reasons'' and told a fan on Twitter soon afterwards: ''Me Mum ain't well (sic).''

Russell later spoke about her illness on his The Trews video blog, saying: ''My mother has currently got breast cancer.''

The funnyman, who is seeking comfort from girlfriend Jemima Khan, also hit out at the CoppaFeel! charity campaign, which encourages women to check their breasts for lumps.

He said he cannot see how using topless models to raise awareness of the illness is helping victims, like his mother.

Russell said: ''I don't feel that this is helping. The NHS, which is slowly being destroyed, that's quite useful.

''The support groups she's attended that the NHS encouraged (are useful), but this, I don't know if it's doing my mum a lot of good (sic).''

Russell's mother, who has suffered a number of bouts of cancer throughout her life, brought him up on her own at their family home in Essex after his dad Ron left when he was six months old.

Russell wrote about Barbara's battle with cancer in his first autobiography 'My Booky Wook' and has spoken out about the disease on a number of occasions.
