in the breast series ( 17,756 patients ) a small deficit of cervical tumours was observed ( o = 16 , e = 2.119 , o/e = 0.76 , p > 0.05 ) , while in the cervix series ( 4817 patients ) a small excess of breast tumours was found ( o = 29 , e = 23.38 , o/e = 1.24 , p > 0.05 ) over a period of 15 years.a theoretical statement of the combined risk of the 2 tumours occurring in the same individual of a general population was developed and was compared with the practical approach of summing the sequence analyses ( complementary analysis ) .
