Table 3 SIR values(95% CI) in relation to tumour type and different time intervals of follow up since diagnosis of gynecomastia. Also number of individuals and personyears for each interval are shown. The lead time between gynecomastia and tumour diagnosis was for esophageal cancer 8 years (6–10 years), skin cancer 6 years (3–25 years) and testicular carcinoma 10 years (3–18) years.
