Welcome to the forum.
I would suggest that you supply more specific information, so that others here might give more useful replies.
Is this an initial Stage IV diagnosis or a recurrence ?
Have you already had prior treatments and / or surgeries ?
What is the exact diagnosis : colon, rectosigmoid, low rectal, single met, multiple mets, liver, lung, both ???? ( Stage IV A or IV B ? )
There is a wealth of information here and to prevent you from having to read thousands of posts !!!!! (BTDT
) ...... the more info you could provide, will yield better answers to your questions. Someone's reply for having a single lung met treated on the west coast ( me ) may not apply to you if you have multiple liver mets and are considering surgeries or HAI on the east coast ...... just as one example.
Please give us more info and ask many more questions as you learn more here !
Best wishes,
CRguy
