Six months after the procedure, this is what he wrote (ref post on June 29, 2012). "However, my experience with cancer pain only started in the last four months or so. In fact, it started after my HIFU treatment in China and I believe it has to do with the dead tumor tissues inside my right abdominal area and also the healing wounds of the tissues and blood vessels after the HIFU treatment"
He had also expected that the HIFU procedure would be able to remove the entire kidney tumour. However, it was only able to remove 90% of it. He discovered this fact only when he was there.
It is not my intention here to speculate on what happened. We also have to bear in mind that after the HIFU therapy, he did not go back to China for follow up. He said that it was not necessary. He was also not closely monitored by a local doctor. Without a scan, he had assumed that the constant pain at his abdominal area was from dead tumour tissues after HIFU. In July this year, doctors discovered that the cancer had spread mainly to his abdominal area causing him great pain and later, breathing difficulties.
Even though we do our research, there may still be many things we may miss or be unable to anticipate, just from reading research material from the internet and books. In his own words. Chang said "What I want to say is that in theory, it may sound very good but in practice, it may not be so simple."
I urge readers to take the time to find out more information as well as get feedback from other patients on any treatment which they wish to pursue. Of course, we understand that cancer patients sometimes feel that they are running out of time. As for the HIFU therapy, researchers in Europe are still doing trials in its use for cancer treatment. But they are not sure how well this will work as yet.
