Amid flurry of new cancer drugs, how many offer real benefits?
Marlene McCarthy's breast cancer has grown relentlessly over the past seven years, spreading painfully through her bones and making it impossible to walk without a cane.
Although the 73-year-old knows there's no cure for her disease, she wants researchers to do better. It's been years, she said, since she has found a drug that has actually helped. McCarthy said she's frustrated that the Food and Drug Administration is approving cancer drugs without proof that they cure patients or help them live longer.
"That simply isn't good enough," said McCarthy, of Coventry, R.I. "I understand [why] that could be satisfactory for some people. It isn't to me."
