My wife had grade 1 oscc in oral cavity and was surgically operated with lymph nodes removal and neck dissection, even though it had not invaded the nodes. It was in 2014. In 2018/may during oral rehab, a small wound possibly caused by a broken tooth, was detected close to the previous site. Was surgically removed and found to be gr1 oscc,but no lymph node spread or spread in adjoining tissues. I am apprehensive of her survival.
