I've been very slowly working on a project to help raise awareness about ME/CFS and want to make sure I have my facts correct before it's complete. I read somewhere that ME/CFS is more prevalent in the US than breast cancer, lung cancer or AIDS combined. I believe this comparison referred to the 1 million estimate of CFS vs. the 4 million estimate. For accuracy, I have been trying to find illness prevalence rates in the US for the illnesses mentioned (breast cancer, lung cancer and AIDS), but have not been able to find them. Can anyone help? I just want to make sure the comparison to CFS remains accurate today. Thanks for any help!
