We have analyzed the possible relevance of HPV infection for breast cancer risk among Iranian women from north part of Iran. Among women with breast cancer, 25.9 had positive test results for HPV DNA in breast tumor samples in contrast to 2.4 of women with noncancer status (P = 0.002). The infection of HPV has increased the risk of breast cancer (OR 14.247; 95 CI 1.558-130.284, P = 0.019). The high-risk HPV genotypes (types 16 and 18) in samples of breast cancer patients were the predominant types (53.34). Other genotypes detected in breast cancer were HPV-6, HPV-11, HPV-15, HPV-23, and HPV-124, and one isolate could not be genotyped compared to HPV reference sequences. While the sole detected HPV in control specimens was HPV-124. Our study reveals that HPV infection and age are the risk factors in breast cancer development in the north part of Iran.
