Sorry you had so much trouble with the old forum. It was frustrating for me contacting the "Program Experts" over and over and have them say they could not replicate the behaviour. I sent them emails from others and still nothing. Completely useless and I wish I had never used the program I do for my website. The entire program is a piece of rubbish with so many glitches all the time. Problem is there is a lot of info on the website and to redo would be worse. It took countless hours to manually change the forum over. The "Program Experts" modified the phpbb to fit their program. Clearly clueless when they did that. Hopefully there will be no more problems for you or anyone else.
I will leave the medical question to the "Experts" I can assure you the "Experts" here in the field of oncology do know what they are doing
