Hello Jennifer, I'm sorry that you too have need of this wonderful group. This is quite a scary stage to be at. Diagnosed, but still waiting for staging and then a definitive treatment plan . I found that once treatment started I was able to relax a bit.
Dont expect everything to happen quickly, it won't. I guess he will have the TORS and neck dissection done together? He will need to have his teeth assessed by an Oncology dentist. Any teeth not in great shape will need extraction prior to radiotherapy. Radiotherapy can not start until the tooth sockets have healed which is about 2 weeks. Radiotherapy does not usually start until about 6 weeks post the surgery to give the tissues time to heal. So, you can see why there seems to be a delay.
Radiation is tough, but it is doable. Come here often for advice and support.
I personally, would not have got through our journey without this site and the support and advice of all on here. I hope we are able to help you in the same way.
