The blindness of a shop manager at 29 years old was caused by two misdiagnoses from doctors.

Andi Peel from Leicester began to experience severe headaches in August 2019 while she was running the Carphone Warehouse mobile telephone store.

After the pain worsened, he saw his GP and was told that he likely had migraines due to the job pressure.

Peel suffered a panic attack that left him confused and with no memory. He was then referred to Leicester Royal Infirmary.

Doctors once more put an end to the stress of work and sent him off.

The tumour was diagnosed in January 2020 after Peel pulled over his car due to severe pain.

Peel was told by his doctor that he has glioblastomamultiforme, which is a rapid-growing tumour that develops in the brain.

He has been completely blinded since the tumor grew despite chemotherapy and radiotherapy.

Mr Peel (picutred in hospital) visited his GP after the pain continued only to be told he was probably suffering from migraines as a result of the pressure of his job.

Following the continued pain, Mr Peel saw his GP. The doctor told him that he likely had migraines due to the job pressure. Doctors once more attributed the pain to stress at work and released him. He was diagnosed with glioblastomamultiforme, which is a rapid-growing tumour that develops in the brain. The cancer has grown and, despite chemotherapy and radiotherapy treatment, he is now completely blind.

Deb Peel (48), a aunt of Mr Peel from Groby, Leicester said that Andi visited his GP who diagnosed him with migraines. But then he experienced confusion and panic attacks and couldn’t recall anything. 

Mr Peel's vision began to deteriorate in October 2021 and he is now completely blind

In October 2021, Mr Peel began to lose his vision and is now totally blind.

“He visited Leicester Royal Infirmary. But they told him it was stress.

“I was shocked. Andi, my third son is similar to mine so it was a shock that I would lose someone so significant.

“When we received confirmation it was a GBM it was almost like death.

Andi was not interested in knowing how long he’d live. However, Google will show you that it takes between 12 and 18 months.

After radiotherapy, chemotherapy and removal of the tumor at Queen’s Medical Centre (QMC), in Nottingham, ‘Andi’ received treatment.

“Since that time, he’s had several seizures, one of which caused him to dislocate both his shoulders.

“Andi has not had stable scans since December 2020. The scans showed that Andi’s tumour had grown and they have told us there is no treatment for him.

His vision has been progressively worsened since October 2021. He is now completely blind. 

Teacher and mother-of-2 Ms. Peel will be walking 10,000 steps daily in February to help raise money for Brain Tumour Research. 

She stated that Andi is the inspiration. He is an unstoppable warrior, who never gave up on himself or felt sorry for him.

“Until faced with this kind of reality, one doesn’t realize how brutal the facts can be.”

Ms Peel said said: 'The inspiration comes from Andi (pictured left, with his cousins) who is so amazing. He's an absolute warrior who has never given up or felt sorry for himself'

Ms. Peel said that Andi (pictured right, with his cousins), is her inspiration. He’s an absolute fighter who has never lost heart or been sorry for his actions.

Brain tumours are the most deadly form of cancer that kills children under 40 years old. Yet, only 1% of national cancer research funding has ever been dedicated to this terrible disease.

“If even a small thing, such as going on a walk to raise funds for other families that don’t have this experience, it is worth every penny.”

Matthew Price, Brain Tumour Research’s community development manager said that Deb was a great supporter of our work. It is only through people like Deb that we can continue to research brain tumors and make a difference for Andi’s battle against this terrible disease.

The best thing about the 10,000 Steps a Day Challenge in February is how you can incorporate your steps into your daily life.

This could include a morning coffee, catching up at a local park with friends, taking the bus less frequently, walking the streets, and walking the dog while on the phone.

“You can even join forces with colleagues or friends to complete your steps.


Glioblastoma, the most serious brain tumor, is the best. In July 2017, Senator John McCain was told he had one.

Figures show that patients are only 10% likely to survive five years following their diagnosis. Average lifespan ranges between 14 to 16 months.

According to The American Association of Neurological Surgeons, three adults will die from glioblastoma for every 100,000 people.

This cancer is more common in those between 50 and 60 years old. There is no connection between glioblastoma development and previous experience with other types of cancers.


Tumors are composed of an accumulation of cells that rapidly grow in the brain. In most cases, there is no family history.

Surgeons say it won’t spread and it will not affect other organs.

Glioblastoma, unlike other types of brain tumors that can be found in specific areas of the brain is not limited to one area. 

What is the best treatment? 

The cancerous tissues are extremely hard to eradicate because they have likely advanced into the brain. 

The surgeon will not remove the entire tumor (or any part thereof) if the damage it does to brain tissue is minimal.

Daily Mail Online was told by Dr Babcar, a Weill Cornell Brain and Spine Center neurosurgeon, in July 2017 that microfibers may spread to other parts of the brain, which an MRI might not detect.

“So even though the tumor has been removed, and the patient is treated with radiation and chemotherapy it can come back.” 


The grade of brain tumors varies depending on their growth rate and severity.

Malignant tumors receive a grade three or four while benign ones get a grade one or 2. 

Glioblastoma can be referred to often as a Grade Four Astrocytoma. This is another kind of brain tumor according to the AANS.


Patients complain often of headaches, blurred vision, difficulty with memory and dizziness.

Some symptoms may be non-specific and can vary between people. 

Patients may experience blindness when their tumor compresses their optic nervous, which links the retina and brain.

Therefore, it is difficult to diagnose this disease from symptoms alone.
