Gynecologic oncology encompasses malignancies affecting the female reproductive system, including ovarian, endometrial, cervical, vulvar, vaginal, and fallopian tube cancers. These cancers collectively represent significant causes of morbidity and mortality in women worldwide, with ovarian cancer being the most lethal and cervical cancer being largely preventable through screening and vaccination.
Gynecologic cancers arise through diverse mechanisms including hormonal influences (estrogen exposure in endometrial cancer), infectious agents (HPV in cervical cancer), genetic mutations (BRCA1/2 in ovarian cancer), and chronic inflammation. Most develop through progressive accumulation of molecular alterations affecting tumor suppressor genes, oncogenes, and DNA repair pathways, leading to uncontrolled cellular proliferation and metastatic potential.
Early detection significantly improves outcomes, making recognition of warning signs crucial - abnormal vaginal bleeding, pelvic pain, bloating, and changes in bowel/bladder habits warrant investigation. Staging determines treatment approach, typically involving surgery, chemotherapy, and/or radiation therapy. Risk stratification based on histology, grade, and molecular markers guides personalized treatment decisions and surveillance strategies.
