Only sign of mother's nine brain tumours was tiny spot on her back

UK mum diagnosed with 9 brain tumours after a small spot on her back was revealed to be stage 4 melanoma.

A UK mother of three was diagnosed with nine brain tumours after noticing a small mark on her back.

 

LONDON, UNITED KINGDOM — A seemingly harmless mark on her back turned out to be the first warning sign of an aggressive form of cancer for 42-year-old mother Gemma Allen. What began as a spot noticed by her husband led to the shocking discovery of nine tumours in her brain and further spread to her lungs.

 

The ordeal began in October 2024, shortly after a short break with friends. One morning, Gemma experienced a strange numbness in her arm. Initially brushing it off, she soon developed more symptoms — difficulty typing, coordination issues, and sensations that concerned her family. After weeks of struggling to get a general practitioner appointment, she called NHS 111 and was advised to go directly to A&E.

 

Doctors nearly sent her home after initial assessments showed no alarming signs. However, a last-minute decision to perform a head scan changed everything. It revealed a mass in her brain. Further scans showed a total of nine brain tumours, one as large as 35mm, and small nodules in her lungs. A biopsy of the skin mark confirmed it was melanoma, a serious form of skin cancer.

 

Gemma began immediate treatment with a targeted therapy pill matched to her cancer’s genetic mutation. Her condition improved quickly, regaining movement and coordination. But within months, her health declined again. A scan revealed the largest tumour had grown by 10mm in less than a week. Doctors told her urgent brain surgery was necessary to prevent permanent paralysis on her left side.

 

The tumour was located in a sensitive region of her brain responsible for movement and sensation. During surgery, electrodes and limb sensors were used to minimize damage. Post-surgery, she faced temporary paralysis and continues to walk with a frame, working hard to regain her independence.

 

Though her cancer is considered incurable, new immunotherapy treatments offer some hope for extended survival. Gemma’s friends have launched a fundraiser to help create a healing garden for her.

 

Now focused on making the most of every day, Gemma is sharing her story to raise awareness. She hopes others won't ignore unusual signs or small changes in their bodies.
