J’Ssiah Walters pictured with his siblings – the youngster who has leukaemia has been left with mottled skin by the drugs used to treat the disease. See SWNS story SWSKIN; A mum has made a heartbreaking appeal to get her three-year-old son lifesaving treatment in America after leukaemia surgery complications left his black skin mottled white. Doctors believed Jssiah Browns life had been saved when his brother Kyerell, seven, donated his bone marrow so they could once again play together. But their mother Jeanene Walters, 28, was handed a devastating blow when they learnt the leukaemia is back and British doctors say they can do nothing for it. The family, of Camberwell, south east London, is now trying to raise £150,000 to get Jssiah state-of-the-art proton beam treatment in the USA, or Israel. The treatment, that the parents of five-year-old Ashya King say cured him of brain cancer, destroys cancer cells directly, leaving healthy tissue virtually untouched unlike in chemotherapy.
