Woman Takes Legal Action After 11 Years of Cancer Treatment Following Alleged Misdiagnosis
A 34-year-old mother is taking legal action against the NHS after spending more than a decade undergoing chemotherapy for a brain tumour she now says she never had.
Becky Jones was just 21 when doctors told her that she had a Grade 4 glioblastoma, one of the most aggressive forms of brain cancer. The diagnosis came after she experienced severe migraines and underwent a brain scan that revealed a mass.
According to reports, Becky was told that she might have only six to 12 months to live. She was subsequently placed on an intensive treatment programme that included chemotherapy and radiotherapy.
More than a decade later, however, experts reviewing her medical records have reportedly concluded that the abnormality was consistent with tumefactive demyelination, an inflammatory condition affecting the brain, rather than cancer.
The case has raised serious questions about diagnosis, treatment decisions and the importance of reviewing long-term medical care.
A Diagnosis That Changed Her Life
Becky’s ordeal reportedly began in December 2012, when a scan identified a mass in her brain. A biopsy was planned to establish exactly what the abnormality was.
However, according to Becky’s account, the initial biopsy results were lost. She says she was later transferred to University Hospitals Coventry and Warwickshire, where doctors diagnosed her with Grade 4 glioblastoma without having seen the original results.
When the biopsy information eventually became available, Becky says it indicated several possible explanations, including a lesion, an infection or tumefactive demyelination.
Despite this uncertainty, she says treatment for cancer began.
She underwent chemotherapy using temozolomide, commonly known as TMZ, alongside radiotherapy. Rather than receiving treatment for a short, defined period, Becky says she continued taking chemotherapy for approximately 11 years.
She estimates that she went through around 156 cycles of chemotherapy.
For someone who had been told she was facing a terminal illness, stopping treatment was understandably frightening. Becky says she was repeatedly led to believe that chemotherapy was keeping her alive and that discontinuing it could result in her death.
The Physical and Emotional Cost
The long period of treatment reportedly had a significant impact on Becky’s physical and emotional wellbeing.
She has described experiencing nausea, fatigue, anxiety, depression, ulcers, stomach problems and constipation. She has also raised concerns about the possibility of early menopause as a consequence of her treatment.
The consequences were not limited to her health.
Becky says her diagnosis affected her career ambitions and prevented her from pursuing her goal of joining the police. Her driving licence was reportedly revoked for two years, further limiting her independence.
She also says that the cancer diagnosis changed the way she lived her everyday life.
Because she believed she had cancer and was undergoing chemotherapy, she was warned that illnesses such as food poisoning could pose serious risks. She avoided family gatherings and says she took additional precautions during the Covid pandemic.
One of the most painful consequences came when her own mother was diagnosed with cancer.
Becky has said that she spent time shielding herself from others because she believed she was seriously ill. Looking back, she feels that she lost opportunities to spend time with her mother during an important period of her life.
Questions About the Original Diagnosis
The situation began to change after Becky stopped taking temozolomide in March 2024. This followed a call informing her that her treatment would end after the retirement of Professor Ian Brown, the consultant oncologist who had supervised treatment for the patients involved in the case.
Becky says that she had previously questioned whether she really had a brain tumour, particularly because she could not see an obvious tumour on later scans. She says she trusted the medical professionals who told her that the chemotherapy was keeping her alive.
By 2025, after years of clear MRI scans, she began questioning the original diagnosis more seriously.
Expert reviews arranged through lawyers reportedly concluded that the biopsy findings were consistent with tumefactive demyelination.
Tumefactive demyelination can produce a mass-like appearance in the brain and can therefore sometimes resemble a tumour on imaging. According to the report, experts reviewing Becky’s case said the condition could potentially have been treated with steroids rather than prolonged chemotherapy.
For Becky, learning that she may never have had cancer was a life-changing moment.
She has described discovering the findings during a conference with clinical experts and said that the reality of what had happened only truly became clear when specialists told her she had never had a tumour.
Wider Concerns About Patient Care
Becky is not the only patient involved in legal action.
More than 40 patients are reportedly taking action against the health service over claims relating to prolonged treatment with temozolomide.
The cases have also attracted attention because of a preliminary review by the Royal College of Physicians. The review reportedly found that patients at the Coventry hospital had routinely received extended courses of the drug despite little or no evidence of benefit.
It also raised concerns about the failure of staff and pharmacy teams to challenge patients who were apparently receiving oral chemotherapy continuously for periods of 10 to 15 years.
These findings have prompted broader questions about how long-term treatment is monitored and how decisions are reviewed when patients remain on powerful medicines for many years.
Professor Ian Brown, who is now retired, is reportedly subject to an investigation by the General Medical Council.
The legal claims and regulatory investigation are ongoing, meaning allegations made against individuals or organisations should not be treated as established facts unless confirmed through legal or official findings.
A Story About the Importance of Review
Becky’s experience highlights the profound consequences that a medical diagnosis can have beyond the treatment itself.
A serious diagnosis can influence a person's career, relationships, family life and understanding of their future. In Becky’s case, she was reportedly told that she might not survive beyond a year and that she would never have children.
Despite those warnings, she later became a mother of two after pausing chemotherapy.
Her story also demonstrates why medical diagnoses can require continued review, particularly when treatment continues for many years or when new evidence emerges.
The case will now move forward through legal and regulatory processes. Becky says she wants answers about how her diagnosis and treatment were allowed to continue for so long and why her concerns were not addressed earlier.
University Hospitals Coventry and Warwickshire NHS Trust has said that affected patients have been reviewed by senior clinicians and that appropriate care plans have been put in place. The trust has also stated that patient safety, experience and wellbeing remain priorities.
For Becky, however, the impact of the alleged misdiagnosis cannot simply be measured in years of treatment. She says it affected her health, ambitions, relationships and the way she experienced some of the most important years of her life.
The case is therefore likely to remain under close scrutiny as the legal claims and investigations develop.
