I'm sorry to hear about your dad's state of health.
The Singapore public health system is well-respected, but MDS is a rare disease, so to find out more about what can be done for your dad, you might have to seek out specialists who understand the disease.
Even without knowing more about MDS yourself, you could try to arrange a consultation with the doctors in Singapore who have the most experience with bone marrow failure diseases, if you can identify them. According to the
MDS Foundation, Dr. Aloysius Y. Ho at Singapore General Hospital is one such expert.
You can also help your dad by learning more about MDS, so you can ask the right questions. I suggest finding out what MDS "subtype" your dad has, and getting a copy of his blood test results to see which blood counts are low, and how low. You might also try to find out what his bone marrow "blast count" is, since that's one measure of risk.
Once you have information like the above, it might become clear whether your dad is eligible for drug treatment. Asking for treatment recommendations is one of the primary reasons to get a second opinion.
Make sure you talk to your dad about all of this, and that he knows you are there to support him. He may have strong opinions about the kind of care he receives, but chances are that you'll be better able to gather information than he will.
