Hi CTS, your friend is fortunate to have you for his support. It will take around 7-10 days to recover from surgery and in the meantime, your friend will get reports which will tell whether the margins were clear and how's the lymph nodes that were extracted.

Depending on the result, oncologist will decide on further course of treatment. If things are good, your friend may need few monthly follow-ups and then every quarter. If not, he may have to go concurrent chemo-radiation. Tell your friend to be brave - will to win this disease is what helps the most.
