My 49 yr old mother has hypoechoic superficial abdominal wall lump of about 6cm in right hypochondrium separate from liver,gb and kidney .reports are attached. Her hb level is only 5 since last year and has persistent abdomen pain and various other problems. Her esr was also 80 recently. Local doctor is giving her mk xone s  antibiotic injection and other gas medicine and she feels some improvement. Is there any test other than biopsy which could confirm whether it's cancerous or not. Pls guide.
