    For study of the curative effects of “Wai Qi” of “Gigong” on the cancer growth and metastasis, 31 animal models of cancer metastasis were used. Since second day after transplantation of U27 cancer, the mice of the “Wai Qi” group were treated for 10-30 minutes every day. The mice of the control group were not given any treatment. 23 and 33 day after transplantation of U27 cancer, the mice were axillary lymph nodes were examined histopthologically.
    It was found that in 16 mice of ``Wai Qi'' quoup ' the lymph nodes metastasis was 1 (l/l6), the lung metastasis was 2 (2/l6) and the average volume of the tumor was 1. 82cm. In 15 mice of the control group ' the lymph nodes metastasis was 6 (6/15) the lung metastasis was 3 (3/15), and the average volume of tumor was 6. 75cm.
    These results indicate that “Wai Qi” of “Qigong” can reduce the tumor volume and metastasis.
