A respiration mimic device, comprising:

• a lung simulant including a chamber having an interior space filled with fluid, a lung mimic, to be contracted or expanded, accommodated at the interior space in the chamber, and a tumor mimic distributed in the lung mimic;
• a driving unit for copying motion patterns of the lung according to actual respiration and contracting or expanding the lung mimic;
• and
• an abdomen simulant for elevating vertically according to contraction or expansion of the lung mimic and copying an abdomen, the abdomen simulant comprising:
• a first rod in which one end is hinge-coupled with the driving rod;
• a second rod, in which one end is hinge-coupled with a fastener, hinge-coupled with the first rod to cross with the first rod;
• and
• a supporting plate coupled with the other end of the first rod and coupled with the other end of the second rod to be slid.
