Classification of ovarian cancer includes epithelial ovarian cancer, germ cell tumors, sex cord-stromal tumors, undifferentiated tumors, among others. The pathological features of ovarian cancer include cell nuclear abnormalities, cell nuclear proliferation, mitotic figures, imbalance in cytoplasm and nuclear ratios, and more. Histological types of ovarian cancer comprise epithelial ovarian cancer, germ cell tumors, sex cord-stromal tumors, etc. Differentiation grades of ovarian cancer include highly differentiated, moderately differentiated, and poorly differentiated categories. 1.3.4 Endometrial cancer Endometrial cancer is one of the most common types of cancers in the female reproductive system, typically occurring within the endometrial layer of the uterus. Symptoms of endometrial cancer include irregular bleeding and dysmenorrhea. Classification of endometrial cancer includes endometrial adenocarcinoma, endometrial adenosquamous carcinoma, endometrial squamous cell carcinoma, among others. The pathological features of endometrial cancer include cell nuclear abnormalities, cell nuclear proliferation, mitotic figures, imbalance in cytoplasm and nuclear ratios, and more. Histological types of endometrial cancer comprise endometrial adenocarcinoma, endometrial adenosquamous carcinoma, endometrial squamous cell carcinoma, etc. Differentiation grades of endometrial cancer include highly differentiated, moderately differentiated, and poorly differentiated categories. 1.3.5 Vaginal cancer Vaginal cancer is a relatively rare type of cancer in the female reproductive system, typically occurring on the vaginal wall. Symptoms of vaginal cancer include vaginal bleeding, pain, and abnormal discharge. Classification of vaginal cancer includes squamous cell carcinoma, adenocarcinoma, undifferentiated carcinoma, among others. The pathological features of vaginal cancer include cell nuclear abnormalities, cell nuclear proliferation, mitotic figures, imbalance in cytoplasm and nuclear ratios, and more. Histological types of vaginal cancer comprise squamous cell carcinoma, adenocarcinoma, undifferentiated carcinoma, etc. Differentiation grades of vaginal cancer include highly differentiated, moderately differentiated, and poorly differentiated categories. 1.3.6 Vulvar cancer Vulvar cancer is a relatively rare type of cancer in the female reproductive system, typically occurring on the skin of the vulva. Symptoms of vulvar cancer include vulvar lumps, pain, and itching. Classification of vulvar cancer includes squamous cell carcinoma, adenocarcinoma, undifferentiated carcinoma, among others. The pathological features of vulvar cancer include cell nuclear abnormalities, cell nuclear proliferation, mitotic figures, imbalance in cytoplasm and nuclear ratios, and more. Histological types of vulvar cancer comprise squamous cell carcinoma, adenocarcinoma, undifferentiated carcinoma, etc. Differentiation grades of vulvar cancer include highly differentiated, moderately differentiated, and poorly differentiated categories. 1.3.7 Nipple tumor Nipple tumors are benign tumors, typically occurring in the nipple and areola tissues. Symptoms of nipple tumors include nipple discharge and nipple retraction, generally without causing pain. Classification of nipple tumors includes nipple adenoma, ductal papilloma, among others. The pathological features of nipple tumors include cell nuclear abnormalities, cell nuclear proliferation, mitotic figures, imbalance in cytoplasm and nuclear ratios, and more. Histological types of nipple tumors comprise nipple adenoma, ductal papilloma, etc. Differentiation grades are generally not applicable to benign tumors. The classification of female cancers based on the site of lesions can assist doctors in more accurately diagnosing and treating cancers. For women, regular gynecological and breast examinations are crucial for the timely detection and treatment of cancers. Additionally, maintaining a healthy lifestyle, including balanced diet, moderate
