Table 1.
Breast cancer (BC) tissues have a higher frequency of high-risk HPV infections than breast adenosis (BA) tissues
| Disease | n | HPV16/18 infection | ||
|---|---|---|---|---|

| ||||
| Negative n (%) | Positive n (%) | P | ||
| BC | 325 | 291 (89.5) | 34 (10.5) | 0.047 |
| BA | 100 | 96 (96.0) | 4 (4.0) | |
| IDC | 246 | 221 (89.8) | 25 (10.2) | 0.856 |
| ILC | 53 | 47 (88.7) | 6 (11.3) | |
| DCIS | 26 | 23 (88.5) | 3 (11.5) | |
Note: BC, breast cancer; BA, breast adenosis; IDC, invasive ductal carcinoma; ILC, invasive lobular carcinoma; DISC, ductal carcinoma in situ. Positives were compared with negatives using chi-square method.
