A young doctor from Bristol, who reached his fundraising target of £100,000 for Cancer Research UK, has died of a cancer that runs in his family.
Dr Mark Sims, 28, died on January 19 after battling malignant melanoma caused by a genetic fault, which also affected his brother, father, aunt and grandmother.
His fiancee, Georgie Latcham, posted a heartbreaking final message online describing his last few hours. She ended the post by saying "I'll never forget the memories and he'll always be my hero".
She added: "watching my 28-year-old fiance cruelly robbed of his sight, hearing, swallowing, walking, speech, along with any chance of a future was heartbreaking and wrong."
Mark Sims was 15 when first diagnosed with skin cancer but was later given the all clear.
In 2015, the disease returned and spread to his lung, liver, spleen and gall bladder.
Earlier this month Mark was given the news that nothing more could be done to treat him, which spurred him to announce he wanted to raise £100,000 for Cancer Research UK.
