Relevance
Breast and uterine tumors represent some of the most frequent neoplastic diseases affecting
women worldwide and are among the leading causes of cancer-related morbidity and mortality.
Breast tumors, particularly breast carcinoma, remain the most common malignancy in
women, accounting for significant public health concerns due to their high incidence and potential
for metastasis. Uterine tumors, most notably endometrial carcinoma and uterine fibroids, are also
highly prevalent and are associated with hormonal imbalances, reproductive health complications,
and long-term morbidity. The study of causative factors is of crucial importance because early
identification of risk factors can improve prevention, screening, and timely management.
Various causes such as genetic predisposition, hormonal influences, lifestyle habits,
environmental exposures, and metabolic disorders contribute to the pathogenesis of both breast
and uterine tumors. Understanding these causes provides the basis for comprehensive health
strategies aimed at reducing the burden of female reproductive system tumors.
Objective
The main objective of this study is to investigate and summarize the primary causative
factors associated with the development of breast and uterine tumors in women of reproductive
and post-reproductive age. Specific objectives include:
To analyze the role of genetic mutations such as BRCA1/BRCA2 in breast cancer and
mismatch repair gene defects in uterine tumors.
To evaluate the influence of hormonal changes, including prolonged estrogen exposure,
obesity-related hyperestrogenism, and use of hormonal replacement therapies.
To identify lifestyle-related risk factors such as diet, alcohol consumption, smoking, and
lack of physical activity.
To highlight the role of reproductive history, such as early menarche, nulliparity, late
menopause, and use of oral contraceptives.
To provide evidence-based recommendations for prevention and early detection strategies
tailored to women at high risk.
Results
Based on analysis of epidemiological and clinical studies, several major risk factors have
been identified for both breast and uterine tumors. For breast tumors, hereditary mutations
(BRCA1/2), family history of breast cancer, hormonal exposure (early menarche, late menopause,
nulliparity), and lifestyle factors such as alcohol use and obesity are significant contributors. In
uterine tumors, unopposed estrogen exposure, polycystic ovarian syndrome (PCOS), diabetes,
obesity, and tamoxifen therapy have been shown to increase the risk of endometrial cancer.
Uterine fibroids, though benign, are strongly associated with hormonal imbalances and
genetic predispositions. Both tumor types show a strong correlation with metabolic syndrome,
which amplifies the effects of obesity, insulin resistance, and chronic inflammation.

Results also indicate that regular screening (mammography, pelvic ultrasound, endometrial
biopsy) and lifestyle modification significantly reduce the risk and improve early detection rates.
Preventive strategies targeting obesity, hormonal regulation, and hereditary risk assessment
are effective in reducing incidence rates in high-risk populations.
Conclusion
Breast and uterine tumors remain a global health challenge due to their high prevalence,
impact on women’s quality of life, and potential lethality. The causes are multifactorial,
encompassing genetic, hormonal, metabolic, and lifestyle-related factors. Identification of these
risk factors is essential for both primary and secondary prevention.
Genetic counseling and testing for high-risk women, combined with hormonal and
metabolic risk management, form the cornerstone of preventive healthcare. Lifestyle interventions
such as maintaining a healthy div mass index, engaging in regular physical activity, limiting
alcohol consumption, and promoting reproductive health awareness are effective strategies to
reduce tumor incidence.
Furthermore, the integration of population-based screening programs, especially
mammography and gynecological examinations, allows for earlier detection and better prognosis.
In conclusion, a multidisciplinary approach that combines clinical, genetic, and lifestyle
interventions is the most effective way to address the causes of breast and uterine tumors and to
improve long-term women’s health outcomes.
