                        My motherinlaw had the surgery 3 weeks ago (I believe her size was 5 cm) and kept it from her kids they told us after she had the surgery done.  The survival rate is 98 % if you have the surgery.  It is only when it ruptures that the rate significantly decreases.  I vote you have the surgery.  Wow you've been through a lot.  My mother inlaw has had the same traumatic 4 years surviving colon cancer and she has survived this too.    God bless
