BRCA2 and breast cancer: Among other BRCA2-related male tumours, pancreatic cancer showed a high risk after breast cancer (overall SIR 1.93) and stomach cancer was increased in men who were diagnosed with breast cancer before the age of 56 years; however, no increase was observed for melanoma in contrast to findings from the SEER study (Auvinen et al, 2002; Hemminki and Granstrom, 2002).
