A woman who woke at night with a "really bad pain" in her arm and chest was diagnosed with an "aggressive" cancer that would kill her without treatment.
Eloise May, 20, initially thought the pain was caused by a horse riding injury, or by coming home drunk, the Liverpool Echo reported.
She had "absolutely no idea" doctors would find a lightbulb-sized tumour in the middle of her chest, compressing almost a third of the vein returning blood from her brain to her heart.
