These studies suggest that common types of cancer in women include breast cancer, which is influenced by genetic, environmental, and lifestyle factors, and endometrial cancer, which shares common etiologic factors and may not be entirely estrogen-independent.

Types of Cancer in Women: A Comprehensive Overview
Gynecological Cancers: Cervical, Endometrial, and Ovarian
Cervical Cancer
Cervical cancer is one of the most prevalent cancers among women. Key biomarkers used for its detection include Squamous Cell Carcinoma (SCC) antigen, Cytokeratin 19 (CK19), and Immunosuppressive Acidic Protein (IAP). These markers have shown high sensitivity and specificity in detecting cervical cancer, with SCC antigen having the highest sensitivity at 98.7% and CK19 the highest specificity at 99.7%. Early detection through these biomarkers significantly improves prognosis.
Endometrial Cancer
Endometrial cancer is another common gynecological malignancy, often detected early when the tumor is confined to the uterus, leading to a favorable prognosis. Biomarkers such as CA19-9, CA125, leptin, thymidine kinase, CEA, CA15-3, and HE4 are crucial for early detection. CA125 has the highest sensitivity (99.7%), while CA19-9 has the highest specificity (95.7%). The dualistic model of endometrial cancer categorizes it into Type I (estrogen-dependent) and Type II (estrogen-independent), with recent studies suggesting that metabolic factors may play a role across both types .
Ovarian Cancer
Ovarian cancer is also a significant concern, with biomarkers like CA-125 and HE4 being essential for its detection. The combination of these biomarkers can improve the predictive values and aid in early diagnosis, which is crucial for better management and treatment outcomes.
Breast Cancer: Types and Risk Factors
Histological Types and Reproductive Factors
Breast cancer is the most common cancer among women globally, with various histological types including ductal, lobular, tubular, mixed ductal-lobular, mucinous, and medullary cancers. Reproductive factors such as age at menarche, age at first birth, and parity significantly influence the risk of different histological types. For instance, the risk of lobular tumors decreases with later age at menarche and increases with later age at first birth. Increasing parity generally reduces the risk of most tumor types except medullary cancers.
Molecular Subtypes
Breast cancer is also classified into molecular subtypes based on receptor status: HR+/HER2-, HR+/HER2+, HR-/HER2+, and triple-negative (ER-/PR-/HER2-). Younger women (adolescents and young adults) are more likely to have aggressive subtypes like triple-negative and HR-/HER2+. These subtypes vary significantly by race/ethnicity and are associated with different prognoses and treatment responses .
Advances in Treatment
Recent advancements in breast cancer treatment have focused on targeted therapies and personalized medicine. Understanding the biological heterogeneity of breast cancer has led to the development of more effective treatment protocols, particularly for advanced stages and drug-resistant cases .
Conclusion
Understanding the various types of cancers that affect women, including gynecological cancers like cervical, endometrial, and ovarian cancer, as well as breast cancer, is crucial for early detection and effective treatment. Biomarkers play a significant role in the early diagnosis of these cancers, improving prognosis and survival rates. Advances in molecular classification and targeted therapies continue to enhance the management and treatment outcomes for breast cancer, highlighting the importance of personalized medicine in oncology.
