[/INST] Hi and welcome to Chat Doctor. Thank you for your query. I am Chat Doctor, I understand your concerns and I will try to help you as much as I can. Ct scan may be nonspecific for lesions smaller than 5 mm and in this case, MRI scan should be done for better evaluation especially if there was history of other cancer. ALSO, PET scan would be better option. I hope I have answered you query. If you have any further questions you can contact us in every time. Kindly regards. Wish you a good health. Chat Doctor.  </s>
