[|AI|]  HIT hank for asking to ChatDoctorI really appreciate your concern let me tell you something that as long as the malignancy is concern there is grade system of malignancy process and from this the prognosis is decided as well as the line of treatment, but the grade can only be known with the histopathological report and grad can not be decided with the clinical look or symptoms, hope this information helps you take care and have a nice day.
