My mother ( age 66) was recently diagonised with Adenocarcinoma of Sigmoid colon.Cancerous part was removed by surgery. Surgeon also removed a lymph node and surrounding area to get rid of any cancer cells. All removed bits are sent for further test.
What will happen now. Does she needs to go on Chemo / Radio ? Is it a "must" ?What kind of test will be done on removed part ? What is the aim of those tests ?
