Don't know where your brother lives, but Houston has a terrific cancer center. My ex-husband's wife owes her life to them. She had a cough and went in for a physical. They discovered it was lung cancer that had spread to her bones, hips, shoulders, skull, and brain.(She'd never smoked.) They put her on chemo and then an experimental drug, and the cancer vanished. It recurred within 6 weeks, though, as a lesion in her liver. Two more experimental drugs, and it looks as though they found the right cocktail. (Prayers for your brother.)
Are you talking about Dr. Stanislaw Bryzinski? He is controversial, but there are people who swear by him.
M.D. Anderson Cancer Hospital is the best in the world, and is also in Houston.
