TORS seems to me to be a far less invasive way to remove cancer as opposed to open surgery. And TORS mixed with radiation (if by RT you mean Radiotherapy) gives you less radiation than 7 weeks of straight radiation, I for one would opt for the combination. TORS usually heals well where as radiation heals slowly and often not completely. Keep in mind every case is unique, every patient is unique. When it comes to radiation we have or should have the option of Proton or Photon and at this, the Pro is much more precise and far less invasive.
The morbidity depends again on each individual and cancer type. Typically these cancers are successfully treated more often than other cancers such as Blood, Breast, Lung, and Prostate cancers. Twenty-three years out for me.
Heck of a way to spend your summer but here you are. Good luck and good healing. You can do this.
