Hi Raj,
I had exactly the same cancer in the cheek seven years ago. My surgery was on March 27 and I did not start radiation until May 20th through July 3rd. Your sisters skin has to heal because radiation will burn her skin. So be patient. I do not have time right now to write more about my case; but I just want to let you know, that you have to trust her doctors about radiation treatment. If they took her cheek out, even her outer skin, it means that they were careful to make sure the cancer was removed. In my case, my cancer was at the beginning stage, so my doctor did not remove my outer skin. I was lucky. Loli

I was diagnosed with HNSSC base tongue left side Metastasis to Lympnodes left neck. My primary ordered a STAT PET Scan on 2/23/22. Confirmed cancer. He referred me to UK Head & Neck cancer center. A University Medical center has all the latest and best treatments for any kind of cancer or medical treatment. I had Chemo/Radiation for 7 weeks started 5/9/22.
I'm still in remission. I'm hoping your Primary referred you guys to Oncologist.
I would like to know how it turned out. My Radiation treatment caused Radiation burns in my throat and an ulcer in jaw on left side, and severe mucositis. It can cause pain, and can affect the mouth, throat, tongue, cheeks, gums, and roof or floor of the mouth. Mucositis is a common side effect of chemotherapy, radiation therapy. Magic mouth wash with lidocaine and benadryl helped some but I had to get nasal gastric tube for at home feedings for months.
