Query: NOT WORTH A LOT OF MONEY!

I HAVE A COPY OF THIS BOOK. IT IS FULL OF INTERESTING INFORMATION ABOUT CANCER BUT REALLY HARD TO FOLLOW IN SOME WAYS. CERTAINLY NOT WORTH A LOT OF MONEY FOR A SOFT COVER BOOK WITH LAST THAN 250 PAGES. A LOT OF THE INFORMATION IN THIS BOOK CAN BE FOUND ONLINE. WHAT A BIG SAVINGS THAT IS!
