Grade I

Grade I refers to the mildest level of severity in a classification system used to describe the extent of a condition, such as a tumor or injury. It indicates that the affected tissue or abnormality is only slightly damaged or abnormal, with minimal impact on function or appearance. Typically, Grade I lesions are easier to treat and may have a better overall prognosis compared to higher grades. This grading helps healthcare professionals determine the appropriate treatment approach and predict likely outcomes.
