This study aimed to evaluate optimal strategies for a breast cancer screening program in Ghana. A continuous growth model was employed to evaluate the natural history of breast cancer in Ghana, from its onset to detection. We estimated tumor growth rates and the age at which symptomatic detection occurs using the maximum likelihood estimation method based on clinical data from the National Center of Radiotherapy and Nuclear Medicine at Korle Bu Teaching Hospital. Our results revealed that biennial screening provided a better trade-off between interval cancers and overdiagnosis than annual or triennial intervals. The simulation results for early screening under biennial intervals showed an average detection age of 47 years for unscreened individuals (control group) and 46 years for those screened (intervention group). While the screening approach (50\u201369 years) with biennial screening proved more reliable than other strategies, the early screening approach (30-65 years with biennial screenings) provided certain advantages in detection for the Ghanaian population. Our findings highlight the importance of early detection and advocate for the systematic adoption of mammography in Ghana and other low- and middle-income countries, contributing to enhanced breast cancer screening and patient treatment plans, as well as informing policy development.<\/jats:p>","DOI":"10.1371\/journal.pone.0323485","type":"journal-article","created":{"date-parts":[[2025,6,17]],"date-time":"2025-06-17T17:23:09Z","timestamp":1750180989000},"page":"e0323485","update-policy":"https:\/\/doi.org\/10.1371\/journal.pone.corrections_policy","source":"Crossref","is-referenced-by-count":2,"title":["Evaluation of optimal strategies for breast cancer screening in Ghana: A simulation study based on a continuous tumor growth model"],"prefix":"10.1371","volume":"20","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-4456-621X","authenticated-orcid":true,"given":"Asamoah","family":"Larbi","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1666-7489","authenticated-orcid":true,"given":"Eric","family":"Nyarko","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Samuel","family":"Iddi","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"340","published-online":{"date-parts":[[2025,6,17]]},"reference":[{"issue":"16","key":"pone.0323485.ref001","doi-asserted-by":"crossref","first-page":"4610","DOI":"10.3390\/jcm13164610","article-title":"Risk factors and preventive measures for breast cancer","volume":"13","author":"M-C Winkler","year":"2024","journal-title":"J Clin Med"},{"key":"pone.0323485.ref002","volume-title":"Screening programmes: a short guide.
