Police are investigating claims that a surgeon wrongly put more than a thousand women through breast cancer operations.
Ian Paterson is alleged to have used a technique on 700 women that is not recommended in Britain because it can leave infected tissue behind.
It is also claimed he carried out operations - including mastectomies - on at least 450 women who didn't have cancer.
ITV News' west of England correspondent Emily Morgan spoke to one of the women involved:
A spokesman for the Heart of England NHS Foundation Trust has said that an external review of breast surgery at Solihull Hospital found that Mr Paterson was not following new guidelines.
In a statement, he said:
An NHS helpline has been set up for patients of the breast cancer surgeon Ian Paterson who is being investigated for possible misconduct.
Dr Aresh Anwar, medical director for Solihull Hospital, said: "We have invited all of Mr Paterson's patients who underwent a mastectomy to see an alternative surgeon for a review of their treatment and care.
"We are keen to hear from any patient who may have concerns or further questions and have set up a helpline to ensure that these can be addressed quickly."
The Heart of England NHS Foundation Trust advice line can be contacted on 0121 424 5473 between 9am and midday, Monday to Friday.
Thompsons Solicitors have also set up a helpline for women who may be affected on 08000 224 224.
A surgeon being investigated over his treatment of more than 1,000 women allegedly misdiagnosed 450 healthy women with breast cancer.
ITV News Correspondent Daisy McAndrew reports:
A woman who claims she had two lumpectomies when her condition was benign said she felt "betrayed" and "angry" she had gone through "unnecessary" surgery.
Thompsons Solicitors, which is pursuing negligence claims for several women, made the following claims about breast surgeon Ian Paterson.
- Mr Paterson allegedly performed invasive breast surgery on 450 women when a biopsy might have been sufficient.
- A General Medical Council investigation into Mr Paterson potentially spans up to 700 cases of an unregulated procedure that involved leaving some breast tissue behind after a mastectomy.
- The solicitors said the breast surgeon worked at numerous NHS and private hospitals from 1994 - including those run by Heart of England NHS Foundation Trust - which covers hospitals in Sutton Coldfield, Solihull and Birmingham.
Surgeon Ian Paterson, who has been suspended by the General Medical Council amid allegations about his treatment of more than 1,000 breast cancer patients, released the following statement:
A grandmother who claims she was incorrectly diagnosed with cancer by a Birmingham breast surgeon said she was "speechless" after learning she never had the disease.
Gail Boichat said she had her breast removed by surgeon Ian Paterson at Good Hope Hospital in Sutton Coldfield.
“My life has been ruined,’’ Mrs Boichat told the Birmingham Mail.
‘‘Paterson told me I had to have a mastectomy if I wanted to survive. Afterwards I was put on a strong drug which had devastating side effects, including the early menopause.
“When the doctor told me that I didn’t have cancer, I was left speechless, shocked, and upset. The lump had been benign all along."
West Midlands Police confirmed they are investigating a local surgeon over allegations he carried out hundreds of unnecessary breast cancer operations:
