Has anyone had problems just with local anestheia. I just found out that the newly approved RFA for metasastasis to the liver or primary liver cancers only involves a mild sedative & a local anesthetic to numb the skin. Each metasastasis takes approximately 30 min. to kill with a heated needle tip. Thanks for all the information so far. I actually have no idea yet what procedure or operation would be called for since we have not had scans yet to know where the cancer is--so I am interested also in experience people have had with general as well. Most likely for colon cancer it would spread to the liver. Any other advice about cancer treatment & PD--such as chemo and fever (I think Dad's tremor was progressed by 104 degree temperature which was not treated properly since noone came when he called) also would be greatly appreciated. It sure is great to have these lists (I am on a colon cancer list as well) to check out what doctors say. Best wishes, Suzanne It
