My words did not put my points forward clearly. Here I will try again.
Comparing apple to apple. Both my friend and I received the same medical procedures and used the same drugs for cancer treatment. I, Singaporean, need to pay SGD$50k in a Singapore Hospital and a Malaysian pays $20k Ringgit in a Malaysia private hospital.
Now, my question is: why is there such a stark difference in the medical cost between Singapore and JB?
As for what class of ward is not important in this case, because for cancer treatment, the patient is not required to be warded. Just need a bed, receive the treatment and we go home. Sometimes, we are allocated to two a room, on other time it could be a four or six bedder.
