title: [Analysis of trace elements in scalp hair of healthy people, breast cancer and hyperplasia patients with XRF method].
abstract: The trace element analysis on the scalp hair of patients with breast cancer and hyperplasia was made using the XRF method and compared with that of healthy people. The hair samples from 42 breast cancer patients, 57 hyperplasia patients and 31 healthy people were collected respectively. The results showed that Mn, Cr and K content in the hair of the patients with cancer was much higher than that of the normal (P < 0.05). Significant differences were also found between patients with breast cancer and with hyperplasia in K and Fe content. The former was much higher than the latter (P < 0.05).
