Depends. If you have thymoma removed by "traditional" technique, median sternotomy (split breast bone), recovery can be several months. Modern techniques will allow you to go home day after surgery and recovery within few weeks or less. I encourage patients to seek out a well trained, modern, minimally invasive thoracic surgeon.
Depends on approach. Standard approach would be through a sternotomy (splitting the breast bone) which would typically require 4-6 weeks recovery. There are minimally invasive alternatives (thoracoscopy or robotic surgery) for selected patients with thymoma that usually have shorter recovery (2-3 weeks).
3-4 week. Usual time 3-4 week.
