Oliva,

So sorry to hear about your sister. You might try to get your sister to
investigate alternatives -- one place to start might be Dr. Lorraine Day's
site --- she claims she cured herself of cancer:
http://www.drday.com/.

Also there is Dr. Burzynski at www.cancermed.com

She might also go to alternativemedicine site for referrals.

Definitely tell her to get off the carbs   and to eat fats -- cancer cells
can't metabolize fats well -- that's why they rely on sugars.

Namaste, Liz
