The tumor has not been treated and the size is 1.5cm. I would advise you not to hesitate any longer and treat the tumor right away. It can still be "cured" with treatment. But if you wait any longer and metastasis occurs, you will miss the opportunity to "cure". As for how to do treatment. There are surgical methods and non-surgical methods, so we need to discuss them together and reach a consensus. If you can accept it, we can help you treat this tumor.
