The only reliable way to determine whether a<unk><unk>  tumour is benign or malignant is through a biopsy. The two methods for acquisition of tumour<unk>  for cytopathological analysis are: *Needle aspiration biopsy, via needle *Surgically, via an incision made into the tumour A pathologist examines the<unk>  under a microscope. If cancer is present, the pathologist can usually determine the type of cancer and its grade. Here, 'grade' refers to a scale used to represent concisely the predicted growth rate of the tumour and its tendency to spread, and this is determined by the degree to which the cancer cells appear abnormal when examined under a microscope. Low-grade sarcomas, although cancerous, are defined as those that are less likely to metastasise. High-grade sarcomas are defined as those more likely to spread to other parts of the body. For<unk> , the two histological grading systems are the National Cancer Institute system and the French Federation of Cancer Centers Sarcoma Group system.<unk> s commonly originate in the upper body, in the shoulder or upper chest. Some symptoms are uneven posture, pain in the trapezius muscle, and cervical inflexibility difficulty in turning the head. The most common site to which<unk>  spreads is the lungs.
