We was told yesterday that my dad has T3 colon cancer. MRI has revealed that it doesn't have looked to have spread anywhere else, but the doctors are suspicious on a couple of the lymph nodes so are questioning if the cancer has gone through the bowel wall. I know that the cancer can spread via the lymph nodes, the doctor did say that his bloods test being "normal" was a good sign. He is soon to start radiotherapy and chemotherapy fir 3 to 4 moths to try and shrink the tumor and stop it spreading. An operation is the last resort the doctor said and thats something we will chat about later down the line. Obviously there is a chance the treatment doesn't work, but if it is does, is this enough to stop if spreading from the lymph nodes into other parts of the body. I'm concerned that they don't know for sure if it is in the lmpth nodes. Also, has anyone had an experience dealing with this cancer at this stage as my worst fears are that it will take over his whole body and result in death.
