A 10cm tumor is indeed very large, but it is not possible to judge whether the tumor is malignant or not by its size. It may also be a benign lesion, such as a giant hemangioma or cyst, which may grow to 10cm or larger. Tumors are mainly divided into benign tumors and malignant tumors according to the nature of the pathology. If it is a benign tumor, even if it grows very large, it is not necessarily life-threatening, but for such a large tumor, surgery is recommended, like liver cysts or liver hemangiomas that are huge, surgical or interventional methods can be considered for treatment. If the lesion is malignant, it means that the stage is late and there may be no way to do surgery for radical treatment, but only to do palliative surgery, tumor reduction surgery, combined with radiotherapy, chemotherapy, targeted drugs and other comprehensive treatment, it is possible that the treatment effect is not very good and can only be seen while treatment.
