Abstract: The Bronze Age skeletons excavated from the Ganguya cemetery in Jiuquan County, GansuProvince were examined for signs of pathology by X-ray. Results indicate the presence of possible echi nococcus disease around 4000 B.P. In one crania we were able to demonstrate bony lesion which may indicate the presence of 3 possible diseases:
(1) Hand Schüller-Christian's disease.
(2) Eosinophilic granuloma of bones.
(3) The metastases of kidney carcinoma.
We also found that these people suffered from osteoporosis at a younger age than modern populations, at the same time we found many bones containing fluor ination disease, which maybe related to local environment which contained high leve1 of fluorine.

Key words: Brain cancer; Echinococcus diseases; Osteoporosis; Bronze Age
