This is the first time I have read that article.
Much of the information there is incorrect. I had a 9 cm tumor abalated last December and so far, so good. The physician who did my ablation told me he has done up to 13 cm (about the size of a grapefruit) by multiple placements of the needle.
And I can't imagine what "unwanted side effect" they might be talking about.
My ablation It cost about 18,000 and surgery would have been 80,000+ including sugery and recovery. I walked out th day of the procedure
and went grocery shopping that night.
Insurance is a problem. Except for liver cancer they still consider RFA experimental so they can refuse to pay. But it make no sense for them to put the patient through torment, then pay 80,000 instead of 18,000.
RFA saved my life. Makes me angry to see thsi slant which might discourage others. Thanks for bringing to to my attention.
