Background: Breast cancer incidence rates are rising in Africa and mortality is highest in West Africa. Reasons for poor survival are multifactorial but delays in seeking appropriate health care result in late presentation which contributes significantly to poor outcomes. Total delays of more than 3 months have been associated with advanced stage at presentation and poorer survival.

Article Synopsis
  • The stromal microenvironment (SME) in breast cancer plays a crucial role in tumor behavior and response to treatment; its relationship with pre-diagnostic factors, especially in women of African ancestry, is not well understood.
  • A study analyzed 792 breast cancer patients to identify how pre-diagnostic host factors influenced SME characteristics using machine learning on tissue images, revealing that certain factors like parity and family history correlated with higher stromal cellular density.
  • The results suggest that epidemiological risk factors may impact tumor biology through changes in the SME, emphasizing the importance of considering these factors in breast cancer studies.

(1) Background: Breast cancer is the leading malignancy worldwide, and in Ghana, it has a poor overall survival rate. However, approximately 50% of cases are cases of early-stage disease, and with advances in breast cancer treatment and improvements in survival, quality of life (QOL) is becoming as important as the treatment of the disease. (2) Methodology: This was a cross-sectional study of survivors who had breast-conserving surgery (BCS), mastectomy only (M) and mastectomy with breast reconstruction (BRS) from 2016 to 2020 at a tertiary hospital in Ghana, comparatively assessing their QOL using and (3) Results: The study participants had an overall (GHS) median score of 83.

Article Synopsis
  • Parental involvement is essential in childhood cancer care, yet there's limited understanding of how Ghanaian parents perceive and react to their child's illness.
  • A study involving 20 Ghanaian parents highlighted that they often identified symptoms through personal observation and their child's reports, usually considering them as minor.
  • Emotional responses to a cancer diagnosis included significant psychological distress, with ongoing fears about their child's health and death, as well as a proactive role in managing their child's treatment at home.
  • The study suggests the need for media programs and health education to improve parents' abilities in recognizing symptoms and responding effectively.

Epidemiologic data on insecticide exposures and breast cancer risk are inconclusive and mostly from high-income countries. Using data from 1071 invasive pathologically confirmed breast cancer cases and 2096 controls from the Ghana Breast Health Study conducted from 2013 to 2015, we investigated associations with mosquito control products to reduce the spread of mosquito-borne diseases, such as malaria. These mosquito control products were insecticide-treated nets, mosquito coils, repellent room sprays, and skin creams for personal protection against mosquitos.

The human fecal and oral microbiome may play a role in the etiology of breast cancer through modulation of endogenous estrogen metabolism. This study aimed to investigate associations of circulating estrogens and estrogen metabolites with the fecal and oral microbiome in postmenopausal African women. A total of 117 women with fecal (N = 110) and oral (N = 114) microbiome data measured by 16S rRNA gene sequencing, and estrogens and estrogen metabolites data measured by liquid chromatography tandem mass spectrometry were included.

Article Synopsis
  • The stromal microenvironment (SME) plays a significant role in tumor biology, impacting factors such as cancer aggressiveness and treatment response, particularly in women of African ancestry who suffer from severe breast cancer types.
  • A study involving 792 breast cancer patients in Ghana utilized machine-learning algorithms to analyze SME characteristics, revealing a connection between tumor-stroma ratio (TSR) and tumor-associated stromal cellular density (Ta-SCD) with tumor grades.
  • Findings indicated that lower TSR and higher Ta-SCD were linked to more aggressive tumors, with factors like parity and family history of breast cancer influencing Ta-SCD levels, while larger body sizes correlated with lower Ta-SCD.

Introduction: breast cancer development is linked to mutant single nucleotide polymorphism of breast cancer type 1 (BRCA1) gene usually harboured within exon 11. It has also been linked to finger dermatoglyphics where certain patterns have been associated with breast cancer. This study suggests a possible relationship between finger dermatoglyphic patterns and single nucleotide polymorphism of BRCA1 gene.

Background: Several anthropometric measures have been associated with hormone-related cancers, and it has been shown that estrogen metabolism in postmenopausal women plays an important role in these relationships. However, little is known about circulating estrogen levels in African women, and the relevance to breast cancer or breast cancer risk factors. To shed further light on the relationship of anthropometric factors and estrogen levels in African women, we examined whether measured body mass index (BMI), waist-to-hip ratio (WHR), height, and self-reported body size were associated with serum estrogens/estrogen metabolites in a cross-sectional analysis among postmenopausal population-based controls of the Ghana Breast Health Study.
