A retrospective study of relative frequencies and relative risks of cancer of 7,169 dogs which were necropsied between 1981 and 1990 at the Institute of Veterinary Pathology of the FU Berlin was performed. In the sample cancer as cause of death accounted for 24.08% of all necropsied dogs. The mean age of dogs with cancer was 10.2 years while dogs without cancer died at a mean age of 5.3 years. Relative risks of cancer were 1.16 for females and 0.86 for males. Cancer was found in 41.9% of all necropsied boxers, which showed the highest relative risk (1.81) of all breeds. Lymphatic and hematopoietic organs and mammary glands were the most frequent site for tumors. Altogether it could be shown that the most frequent tumors were of epithelial origin (43.91%).
对1981年至1990年间在柏林自由大学兽医病理学研究所进行尸检的7169只狗的癌症相对频率和相对风险进行了回顾性研究。在样本中，癌症作为死亡原因占所有尸检狗的24.08%。患癌症的狗的平均年龄为10.2岁，而未患癌症的狗平均死亡年龄为5.3岁。女性患癌症的相对风险为1.16，男性为0.86。在所有尸检的拳师犬中，41.9%发现患有癌症，这在所有品种中显示出最高的相对风险（1.81）。淋巴和造血器官以及乳腺是最常见的肿瘤部位。总的来说，可以表明最常见的肿瘤起源于上皮组织（43.91%）。
