The problem is Thai National Health Service (NHS) don't yet offer breast cancer screening. I have read they propose to do so, however, it will be limited to age 40-59 AND with immediate family history. Even when it's in place my wife wouldn't qualify. Agree, Bangkok Hospital would have treated my wife. The lady cancer doctor told her she also worked in NHS and suggested my wife could take the results/reports to a Government hospital for them to treat her. Surgery, chemotherapy and radiotherapy has/will be given at our Regional Government Hospital.
Don't have much faith in alternative/traditional/herbal remedies myself. Two years ago my brother-in-law passed away at age 56 from kidney failure. Zero sympathy from family because he had long since refused to take prescription medication, preferring Chinese Herbal remedies.
My wife has had three Covid jabs before refusing to have any more. Myself, five to date and seeking more. Her two friends I don't know about.
