Additionally, through this study, we aimed to investigate the impact of tamoxifen treatment, an anti-oestrogen drug used following breast cancer treatment, on histopathological changes. Breast cancer is the most common type of cancer and cause of death in women worldwide. Cervical cancer ranks as the second most prevalent form of cancer among women globally, with prevalence rates ranking just behind those of breast cancer. Human papillomavirus (HPV) positivity is a requirement for the development of cervical cancer, although it is not the sole factor responsible. Materials and Methods: A comparison was made between the histopathological results of 52 patients diagnosed with breast cancer, who tested positive for HPV in routine cervical cytological screenings and underwent colposcopic biopsy, and 230 cases without any abnormalities. A study was conducted to compare healthy individuals between the ages of 30 and 65 who were diagnosed with breast cancer and those who did not have breast cancer. The participants underwent HPV screening as part of the national cervical cytology screening programme. Results: The average age of those diagnosed with breast cancer was 46.73 \u00b1 7.54; in comparison, the average age of participants in the control group was 47.49 \u00b1 7.95. There was no statistically significant difference in age between the two groups (p: 0.530). A total of 51 cases (98.1%) of breast cancer were found to have actively used the anti-oestrogen drug tamoxifen for a duration ranging from at least 6 months to 5 years. One patient (1.9%) in the breast cancer group did not use tamoxifen. During routine cervical cytological screenings, it was observed that both breast cancer cases and healthy cases tested positive for HPV. The most commonly detected types of HPV in both groups were HPV 16 and 18, with rates of 73.1% noted in the breast cancer group and 92.6% noted in the healthy group, results consistent with the rates found in the general population. HPV 16 was found in 58.7% of participants in the control group and 42.3% of participants in the breast cancer group. There was a statistically significant difference between the two groups (p: 0.032). There was no statistically significant difference observed between the two groups in terms of normal, high-grade cervical intraepithelial lesions (HGSILs); low-grade cervical intraepithelial lesions (LGSILs); and chronic cervicitis histopathological lesions based on colposcopic and endocervical biopsy results, smear cytology, and HPV results (p-values of 0.913 and 0.877, respectively). Conclusions: Our study results indicate that tamoxifen treatment, an anti-oestrogen drug administered for chemoprevention purposes in the management of breast cancer, does not lead to an increase in abnormal histological changes in the cervix uteri. In all cases of breast cancer, gynaecological examination and cervical cytological screening should be advised.<\/jats:p>","DOI":"10.3390\/medicina60081268","type":"journal-article","created":{"date-parts":[[2024,8,6]],"date-time":"2024-08-06T10:54:24Z","timestamp":1722941664000},"page":"1268","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["The Impact of Tamoxifen Usage in Breast Cancer Patients on the Development of Histopathological Lesions in the Cervix Uteri"],"prefix":"10.3390","volume":"60","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-8613-2711","authenticated-orcid":false,"given":"Ferhat","family":"Cetin","sequence":"first","affiliation":[{"name":"Department of Obstetrics and Gynecology, Private Osmaniye Park Hospital, 80010 Osmaniye, Turkey"},{"name":"Selimiye, B\u00f6lge Trafik Yan\u0131, Musa \u015eahin Bulvar\u0131, Merkez, 80010 Osmaniye, Turkey"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6385-4730","authenticated-orcid":false,"given":"\u0130lkan","family":"Kayar","sequence":"additional","affiliation":[{"name":"Department of Obstetrics and Gynecology, Osmaniye State Hospital, 80000 Osmaniye, Turkey"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0009-0003-1506-6061","authenticated-orcid":false,"given":"Goksu","family":"Goc","sequence":"additional","affiliation":[{"name":"Department of Obstetrics and Gynecology, American Hospital, 10000 Prishtine, Kosovo"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1939-3743","authenticated-orcid":false,"given":"\u00d6zer","family":"Birge","sequence":"additional","affiliation":[{"name":"Department of Gynecological Oncology, Niger Turkey Friendship Hospital, Niamey 920271, Niger"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2024,8,6]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"6","DOI":"10.1186\/1447-056X-7-6","article-title":"Breast Cancer in Iran: Need for Greater Women Awareness of Warning Signs and Effective Screening Methods","volume":"7","author":"Montazeri","year":"2008","journal-title":"Asia Pac.
