Malignant fibrous histiocytomas are often difficult to see on an x-ray if the tumor is in the soft tissue. These growths require diagnosis and assessment by a doctor with expertise in tumors of the extremities. An MRI or CT scan can diagnose MFH tumors. Biopsies can identify the type and grade of the tumor. A PET scan will determine whether the cancer has spread to other parts of the body, such as the brain.
