stage IB soft tissue sarcoma


(...TIH-shoo sar-KOH-muh)
Stage I is divided into stages IA and IB. In stage IB, the tumor is low-grade (likely to grow and spread slowly) and larger than 5 centimeters. It may be either superficial (in subcutaneous tissue with no spread into connective tissue or muscle below) or deep (in the muscle and may be in connective or subcutaneous tissue).
