After reporting my tumour to doctors 18 months ago, I was diagnosed as having incurable cancer.

Katherine Mills noticed a small lump in her right knee. She thought it might be due to her severe fatigue at university.

Katherine, a communications professional, was diagnosed with incurable breast cancer after she visited four doctors in 18 months.

Katherine was just four months old when she was diagnosed at 22 with Metastatic Angiomatoid Fbrous Histiocytoma.

Katherine, 26, is a Londoner who is currently living with incurable breast cancer. Katherine is trying to help others on their journey.

She has been working alongside Like, a peer support app for cancer patients and survivors, as she says she wants everyone impacted by cancer to have somewhere safe to discuss their experience.

Her own personal experience began in 2016, when she developed a persistent cough that sometimes produced pink sputum. She also noticed a lump at her knee.

Her GP then prescribed antibiotics for a chest problem. Katherine suffered three episodes of fainting on public transport. Katherine’s mum encouraged Katherine to return to the GP.

Katherine stated: “I had a test of my blood and was given iron for anaemia.  This anaemia was monitored, and after one particular blood test my GP called me and told me to go to A&E because my results were worrying.

“I had low haemoglobin so I was admitted to the hospital and given two units of blood by transfusion.

“While I was in hospital, I pointed out the lump behind my knee, but the doctors said it was a ganglion, and nothing to worry about.”

Katherine stated that she was referred to Katherine by her doctor for further tests. These revealed that Katherine had a very high CRP (Creactive Protein) level.

She was then referred back to the Rheumatology Department, where further tests were performed.

Katherine was close to finishing her English Literature & Creative Writing degree.

“I was writing essays from hospital beds and wards”She agreed. The university couldn’t give Katherine a large extension because she didn’t have a clear diagnosis.

She received just three extra weeks of instruction and graduated with a 2:1.


Katherine was then referred to the Renal Department where she was diagnosed as having Granulomatosis and polyangiitis, a rare autoimmune condition.

The treatment included steroids and low-dose chemotherapy agents. However, Katherine still suffered from symptoms.

“By this point, I was also coughing up blood. I was also referred to a respiratory specialist in the hospital. I had a bronchoscopy which was inconclusive. They didn’t find lung cancer cells, and so they ruled out cancer”Katherine said.

Katherine said that Katherine was becoming more dependent on blood transfusions. She had a haemoglobin of 60, when it should have been 120.

“I was also suffering from night sweats – as many as six incidents in a single night. I lost weight, I was vomiting and I was extremely exhausted.”

Know the signs – what is Angiomatoid fibrous histiocytoma (AFH)?

AFH, a rare soft-tissue tumour, has been linked to EWSR1/CREB1 gene fusion.

These are the symptoms  

  • Fainting 
  • Fatigue 
  • Coughing Blood 
  • Weight Loss 
  • Night Sweats 
  • Lump 
  • Joint pain 
  • High Temperature 
  • High Inflammation Markers 

Katherine was suffering with lung lesions and St Thomas and Guy’s hospital was trying to find out what was causing them to grow.

The lump at her back continued to grow. It was first diagnosed as a varicose vein and then as pseudo-aneurysm.

She was placed on treatment in January 2017 for an autoimmune condition she had been misdiagnosed. This was the reason she felt severe pain in her lump, so in March 2017, she received morphine.

Katherine was then referred by the Royal Marsden, who performed a biopsy on the lump. The results were inconclusive. The lump was now the size of an egg and they decided to perform surgery.

“When I went in for surgery, I was prepared to wake up without a leg, depending on what they found in the operating theatre”Katherine said.

Experts examined the leg lump and discovered that it was an uncommon sarcoma called Angiomatoid Fibrous Histiocytoma.

Katherine added: “In June 2017, I underwent an investigative surgery at Guy’s Hospital to remove a piece of the lesion for analysis.

“The sample from my lung was compared with the sample from my leg, and the results confirmed that the lesion in my lung was cancerous and was the same type as the tumour from my leg.

“At that point, I was using an electric wheelchair. My face had been affected by long-term high-dose steroids treatment and I had two large scars from my surgeries.

“But I was still hopeful. Naively, I assumed that now they had identified what was wrong with me, I would receive treatment and begin to recover. “

Katherine informed her that she had an advanced illness with no cure. “Angiomatoid Fibrous Histiocytoma is usually found in the limbs and is treated with surgery. I had tumours in my lungs, liver, spleen, and lymph nodes. Surgery was simply not an option.  ”


She was diagnosed with cancer and began palliative care. However, she was so sick that she couldn’t tolerate chemotherapy.

Katherine was treated in ICU and other types of treatment.

She also added: “My hair fell out and I lost about three stone in as many weeks. My face was still swollen from steroids, but my legs looked like sticks.”

Katherine’s cancer specialists have continued to search for drugs to help her. She started Paclitaxel in 2018, which is used commonly for Breast Cancer.


Alike is an app that assists people in dealing with the challenges of living with cancer.

The Alike app launched by 27-year-old, two-time cancer survivor Brad Gudger, allows users to ‘swipe’To connect based upon a combination of diagnosis, stories, or interest. Individuals can find patients and survivors that they can communicate with on their terms. The app aims to combat the loneliness associated with cancer, by giving people the space to talk through experiences to those others that understand.  

The launch comes after data found that 83 per cent of young people experience loneliness during and after treatment.    

Cancer and loneliness is a growing issue. Each year, approximately 367,000 people are diagnosed as having cancer.  In various studies in the UK, it has been found that 80.7 per cent of young people with a long-term illness or disability reported feelings of loneliness .

Katherine explained that all things are affected by cancer, and hopes that the app will change this.

She stated, “Reach out and talk to your healthcare team. Ask questions. Participate in your own treatment plan. Diagnosis is a lonely place – you might feel like you’ve been catapulted into a parallel universe.

“Everyone else is the same, but you’re undergoing a huge life change. And really, the only people who understand that is people who’ve gone through it. So, I’d genuinely have to say: download the Also app. Having somewhere to vent and talk makes a difference.” 

She stayed on this until March 2020 when she was diagnosed with a fungal chest infection and had to pause chemotherapy to begin anti-fungal treatment.

Katherine received treatment for the first time in March 2021 after her September infection was cleared.

She said, “When I was diagnosed with cancer, I accepted the term.” ‘terminal.’I was aware that my life would be shorter, so knowledge became my weapon.

“Now I have left treatment and been lucky enough to have stable disease, I say that I am living with incurable cancer. 

“There is no known cure for Angiomatoid Fibrous Histiocytoma except surgery, and the position of my remaining tumours makes surgery and other interventions impossible.”

Katherine is now urging others to seek help and support if they have been diagnosed with cancer
