I am 55 & diagnoses with colorectal cancer in December 2010 (sigmoid by pathology, but surgeon called it rectal).  I was stopped after 7 cycles of FOLFOX 7 (neutropenia, fever, anemia).  I only received 3 weeks of 5FU during radiation, because of severe diarrhea.  I was put on medrol dose pack on June 3 (when radiation stopped), but continue with severe diarrhea, weight loss, and severe abdominal pain and cramping ( despite GI muscle relaxants).  What can I do?

Summarized question: How can colorectal cancer be further treated?
