A six-year-old boy with leukaemia has vowed: "I will kick cancer's butt."
Jacob Salmon has acute lymphoblastic leukaemia – an aggressive childhood cancer. He has had chemotherapy and surgery and many courses of steroids.
Jacob, who turned six last month, said: "I know what I am fighting. It hurts sometimes but I am not scared of it. I will kick cancer's butt."
After the leukaemia was discovered nine months ago, Jacob had two months of intensive treatment at Sheffield Children's Hospital.
His mum Joanne Salmon, 43, from Hull, told his local paper Hull Daily Mail: "It was the most terrible time. Jacob stopped breathing three times. Each time I thought it was over and each time I thought it was goodbye. But he is an unbelievable fighter and he is still fighting now."
Since the cancer was discovered, Jacob has had 500 hospital procedures including chemotherapy sessions, lumbar punctures and blood transfusions.
Miss Salmon now wants other parents to be aware of the symptoms.
She said: "I remember one day Jacob was fine and the next, he had chapped lips and stiff legs. He was complaining and he was lethargic.
"I thought he was messing about to be honest, but I dragged him to the doctors.
"The next thing I remember is being referred to Sheffield Children's Hospital and receiving the devastating news that my beloved little boy had cancer.
"You think it will never happen to you, but it can.
"I almost didn't take Jacob to hospital but I am so glad I did because he may not be here today otherwise. I would urge all parents, if they are having any problems with their child's health, to get to a doctor. You cannot be too careful."
The diagnosis meant Jacob was unable to start at school. But in September he will spend one hour a day in classes.
Jacob, who has lost his blonde hair five times, still faces three more years of treatment to defeat the disease completely.
"But we cannot give up after coming this far. We will win."
