"That's what I wanted the most.

But I'm afraid, no such luck.

I'm learning the hard way that I need to take things slowly, a little at a time in eye-drop quantities."It was Loney's partner, Dan Hunt, who finally began to reveal the brutal toll of the pair's long separation.

Avastin, a biologic agent to target cancer cells specifically, was approved a year ago and is tripling response rates in colon cancer patients.

Most of the standard chemotherapy agents still cause side effects in many patients, but administration of antinausea and antidiarrheal medications and others helps control or minimize many reactions.For those patients whose cancer has metabolized to the liver, two new treatments are available.

They are radiofrequency ablation, which uses electrical currents to destroy the tumor, and implantation of a radioactive isotope (yttrium) to do the same thing.Also in development are a new vaccine to boost immune system response, and the use of biologic agents to prevent colon cancer or its recurrence.
