Hi @tucsonfunnyfarm, welcome to the group. I'm sure that you must be reeling from the new of stage 4 colon cancer. You're not alone. Other members like @brenz @komalkochar @sc1218 and @tressa are living with stage 4 or caring for someone living with stage 4. You might be interested in these discussions too:

Tucsonfunnyfarm, is this your first diagnosis of colon cancer or is it a recurrence of cancer?
