Objective: To perform the detection and typing of human papilloma (HPV) virus in biopsy samples of breast tissue invasive ductal cancer. Methods: Cross-sectional study of 57 biopsies of invasive ductal carcinoma, and 41 biopsies of benign breast lesions of Venezuelan patients were evaluated using the PCR-RFLP technique for the presence of the human papillomavirus genome. The OR risk was evaluated by statistical analysis using SPSS package. Results: Thirty-three (57.9%) of invasive ductal carcinoma samples had a positive result for human papillomavirus, 19 of them could be classified as: HPV-6b 15.15%; HPV-11 3.03%; HPV-18 12.12%; HPV-33 27.27%; HPV-45 3.03% and HPV-58 3.03%. This group 42.4% were positive not determined for the presence of virus DNA. Six biopsies of benign lesions (14.6%) had human papillomavirus infection, determining for themselves the types HPV-6b 33.33%, 16.67% HPV-11, HPV-33 16.67% and 33.33% not determined positive. It is statistically determined that the presence of human papillomavirus in breast tissue 10.77 times increases the possibility of developing invasive ductal carcinoma. Conclusions: These findings corroborate the results of other researchers, placing human papillomavirus as a possible agent involved in the immortalization of epithelial cells of the breast.
