To be able to deal with these tumors, which often affect several organs, the unit comprises various surgical specialists: Gastroenterologist, Urologist, Gynecologist, Orthopedic Surgeon, Plastic Surgeon and Vascular Surgeon. On occasions, before and/or after surgery further treatment is required with chemo and/or radio therapy and, therefore, the unit works with Medical Oncologists and Radiotherapists specialized in these tumors. In addition, other specialists like Radiologists, Anatomopathologists, Nutritionists or Stomal Therapists work together to make the unit work.
