Thanks for the reply, Barbara - but nothing I read there (or anywhere else) indicates there is a current, effective home treatment that is effective on lung tissue.
I stand with my earlier statement that, like many other newer therapies, this one is "not ready for prime time" - especially using devices available on-line without a prescription, and being used without medical supervision because there can be significant risks to improper use of infrared lights.

@blm1007blm1007, Hi Barbara, I do believe you are referring to a different doctor Anderson.
The doctor I was referring to is dr. Paul Anderson, he is an educator and a clinician in alternative medicines for chronic illnesses and cancer. He is in Seattle (Washington). He gives many detailed talks on YouTube, some for laypeople and some for practicians.
Best wishes of great health to all of us!
