The most common way to test someone for<unk>  is to take a biopsy. Other tests like x-rays, CAT scans, and MRI's can suggest that cancer is present, but only an examination of a piece of the tumor can make a definite diagnosis. Types<unk>  is classified into 3 types: * Type I is multicystic * Type II shows thickening areas (nodules) within this cystic lesion * Type III shows solid masses. Type I<unk>  is made up of mostly cysts, and may be hard to distinguish from benign lung cysts, and there is some evidence that not all type I<unk>  will progress to types II and III. Types II and III are aggressive, and cerebral metastasis is more frequent in<unk>  than in other childhood sarcomas.
