How long is recovery from tumor removal?

Varies for tumor. Recovery rom tumor surgery depends on the organ from which the tumor is removed and the nature and size of the tumor. Breast excision for Ca heals in several days at home. Colon Ca removal takes about 1 wk to heal. Pancreatic Ca surgery with multiple anastomosis can take 2 wks to heal before going home.
Ambiguous. I am sure you can understand, but your question is perhaps the very definition of ambiguous. What tumor? What kind of surgery? Why you are not asking this of the surgeon planning the procedure? What your medical history and current status of your health is?
