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.

In his final few hours he was surrounded by all of us, we held his hand and kissed him. He passed away and then we sang his favourite songs to him with the music therapist and his guitar. These were songs Mark had sang with the music therapist when he was admitted to the Marsden in early January. Mark had asked the man to learn 'our' song which we would have had our first dance to, and this was the last song we sang to Mark. This meant so much to us and I didn't want to let go of his hand.

We are devastated, and it hasn't quite sunk in that I'll never see him again. Thank you so much for all your messages, they mean the world to me and I'm trying to reply to all of them. Mark really appreciated you all, and I'm so grateful he got to see his justgiving page reach over £100,000 for Cancer Research UK.

He has touched many people's lives and I am so proud of him and feel so privileged I got to spend the time with him that I did. We had amazing times, and he would've had a beautiful future with a great career as a doctor but cancer stole this from him. He was determined to raise as much awareness as possible to beat Melanoma (an aggressive form of skin cancer that affects too many young people). He donated his body to research to help them find further answers to beat this disease, he's written a book and he'll continue to raise money for Cancer Research UK. I'll never forget the memories and he'll always be my hero xxxx
