[Liver tumors and oral contraceptives].

Benign liver cell tumors in young women are reported with increasing frequency. An association between benign tumors and oral contraceptive use was first suggested in 1973 by Janet Baum. During the past ten years we have observed 15 benign liver cell tumors, all of the focal nodular hyperplasia type. Ten of the 15 women were taking or had taken oral contraceptives. This association was found not to be statistically significant (0.06 greater than p greater than 0.05). We also diagnosed 2 liver cell carcinomas in women who had taken contraceptives.
