Veteran health service investigator Sir Ian Kennedy delivered his damning verdict on the Heart of England NHS Foundation Trust.
The trust's hospitals included Solihull Hospital where surgeon Ian Paterson treated hundreds of women with breast cancer with partial mastectomy over a six year period.
The treatment left them exposed to risk of cancer recurrence and mostly the women believed they were to undergo full breast removal, the report reveals.
Sir Ian's report tells how nurses and other doctors struggled to raise concerns about Mr Paterson's practices.
Eventually he was subject to disciplinary proceedings - but this meant nothing was done to alert his patients to the risks they faced because of "confidentiality."
Mr Paterson had joined the hospital in 1998 and was suspended from practice by the General Medical Council in October 2012 and by his employers in May 2011.
The first internal report on his work was produced in 2004, Sir Ian says, but did not deal with the issue of patient consent and made no recommendations on the partial nature of the breast removals.
The report says the surgeon was "charismatic and charming and was much-liked by his patients. He was not, however, a team-player in an area of care which is absolutely dependent on clinicians working efficiently and effectively as a team." He was also seen as "highly effective" and "efficient".
It says oncologists treating the women felt "ignored" and regarded management as remote. Sir Ian says they should have taken their concerns further.
Even after 2007 the response of senior managers at the hospital was neither sufficiently “robust nor rigorous," Sir Ian says.
A statement from trust chairman Lord Philip Hunt said yesterday the findings were "shocking."
The trust said it was giving a "full and unreserved" apology to patients and staff.
A new study suggests the perfume may have powerful properties to treat ovarian cancer.
It comes from a tree found in Africa and Arabia, the Boswellia sacra tree, and has long been used as a herbal medicine for problems such as asthma and skin disease.
Researchers from Leicester University, UK, have gained backing from the government of Oman to research the spice.
Now laboratory studies suggest a compound known as AKBA (acetyl-11-keto-beta-boswellic acid) can kill cancer cells in the late stage of the disease.
Researcher Kamla Al-Salmani said: "After a year of studying the AKBA compound with ovarian cancer cell lines in vitro, we have been able to show it is effective at killing the cancer cells. Frankincense is taken by many people with no known side effects.
"This finding has enormous potential to be taken to a clinical trial in the future and developed into an additional treatment for ovarian cancer."
Fellow researcher Dr Mark Evans said: "What has been most surprising is that the cells we have tested which are resistant to chemotherapy have shown to be more sensitive to this compound, suggesting frankincense may indeed be able to help overcome drug resistance, and lead to an improved survival rate for patients with late-stage ovarian cancer"
Some 30 NHS trusts have signed up to an alcohol-free January project.
Campaigners hope that by persuading people to avoid alcohol in the New Year they can prevent the pleasures of the festive season turn into long term dependency on drink.
The project is being backed by NHS Employers, Public Health England and Alcohol concern.
Participants will get daily tips on how to resist temptation.
NHS Employers chief executive Dean Royles has already taken the January "pledge."
He said: "It's hard to talk about alcohol consumption without sounding like a killjoy at Christmas time, when people’s shopping trolleys are filling up with festive favourites. It is a really important health issue and right that we help set a good example.
"This season is always tough on the NHS and alcohol plays a big part in this. It increases demand on A&E and puts pressure on staff, who want to enjoy the celebrations without it affecting their life-saving work.
"The alcohol consumption of NHS staff is pretty typical of the wider population but I'm confident many will go the extra mile and have a Dry January, helping signpost others to change where alcohol has become a habit."
Professor Kevin Fenton, of Public Health England, said: "Going dry in January can provide an opportunity to reassess drinking patterns, break any bad habits and reset the dial on alcohol consumption for a healthier future."
And some of the 17 cancer specialties at the Colchester Hospital University NHS Foundation Trust are not meeting safety standards, according to the report commissioned by NHS England.
An inquiry team says it uncovered new problems in the hospital group following the scandal about false performance reports being issued by the hospital.
There have been allegations that staff were bullied to suppress concerns.
Investigations are also under way to see if patients were removed from waiting lists without doctors knowing.
The hospital is already under investigation by Essex Police over allegations of fraud.
Local NHS England director Andrew Pike said: "This has been a major undertaking but NHS England - and its health partners - is committed to do everything it can to ensure that the Hospital provides safe care to its patients."
The hospital says it has appointed a new cancer medical lead and a new cancer services manager and is about to appoint a lead cancer nurse.
It said there was little evidence of the problems placing patients at serious risk - as one year survival rates from cancer in the district are a little lower than English rates.
Medical director Dr Sean MacDonnell said: "The report identifies a number of problems in our cancer services which are extremely concerning but which we have started to address.
"However, it is important to stress to current cancer patients and their families that the main issues are with our processes - which we are determined to put right - and the report does not question the quality of chemotherapy, radiotherapy or surgery for patients with cancer."
