Hi sir, My father was having parotid swelling. Last month surgery was done and they removed and sent for biopsy. Few days back biopsy reports came and they informed us it's low grade cancer. Doctors told us to go for radiation treatment for 6 weeks(5days per week). Final Impression in biopsy report was "left total parotidectomy specimen, low grade adenoids cystic carcinoma,pT2 pN0,margins involved by the tumour." Could you please let us know is it really required radiation? Or any other way to cure the decease? Please find the attached reports for reference. Thank you.
