Leukaemia patient William Tam Wai-leong welcomed the idea of a mandatory medical saving and insurance scheme but said there should be more flexibility in how the money could be used. Mr Tam, 31, was diagnosed with leukaemia, a cancer of the blood, three years ago and has since spent about HK$20,000 a month on drugs and treatment. 'I can only afford the drugs thanks to my parents' financial support. Otherwise, it is totally impossible,' he said. Mr Tam said he now took four Imatinib pills every day, which cost him HK$18,400 a month. Imatinib is not provided by the Hospital Authority. Mr Tam was not eligible for assistance from the Samaritan Fund because he could not pass the asset-limit means test. He also spends more than HK$1,000 a month on Chinese medicine. Mr Tam said he used to work as a salesman earning more than HK$25,000 a month but had to quit after contracting the disease. He said he now earned about HK$10,000 a month by doing some part-time work. 'In the next 10 years, I will need over HK$2 million to buy drugs. How can I save up so much money?' He said he was willing to make mandatory medical savings that would help him after retirement. But he wanted a more flexible scheme that would allow him to use or claim money whenever he needed to cover his medical expenses. 'What if there is a medical breakthrough with a cure for leukaemia when I am 40 and I need a big sum of money to pay for it?'
