Hello Scott
I have been having HBO on a weekly basis for over five year now but under pressure as that is more beneficial but before I started I did contact a professor at Dundee university who was an expert in HBO, because I did not want to compromise the treatment I was having at the time and if I change treatments I always ask them.
Now can I say it has helped ?? Impossible to quantify but it has helped with keeping up my hemoglobin and energy levels, the one thing I always remember that the professor said in his email is that cancer hates oxygen I hope it does help you.
Regards
Peter
