Malignant Uterine Tumor

Malignant uterine tumor arises in the vaginal portion of uterus and cervical canal. Cervical cancer spreads directly to vaginal fornix/wall, upward to uterine corpus, laterally to pelvic tissues, anteriorly to bladder, posteriorly to rectum. Lymphatic spread: paracervical/internal iliac/external iliac/inguinal nodes; late supraclavicular/systemic nodes. Hematogenous metastasis less common: lung/liver/bone. Cervical cancer is one of the most common gynecologic malignancies.

Common Symptoms

Pelvic heaviness; increased vaginal discharge; vaginal bleeding; cachexia; fever; uterine bleeding; primary dysmenorrhea; watery black vaginal discharge; weight loss

Causes and Pathogenesis

Genetic predisposition: ~20% of endometrial cancer patients have family history (2x cervical cancer). Chronic cervical erosion/inflammation may progress to cancer. Smoking: lowers immunity, accelerates cancer; produces carcinogens. Sexual activity: no sex = rare cervical cancer; early/improper sex = higher risk; >2 partners = significantly higher risk. Endometrial hyperplasia = precancerous; simple 1%, complex 3%, atypical 30% progress to carcinoma. Anovulatory DUB/PCOS/functional ovarian tumors require estrogen long-term → endometrial change.

Treatment

Drug, surgery

Preventive Measures

Avoid unclean sex; no sex during active genital herpes. Abstain during treatment; partner checked. Keep lesions clean/dry. Prevent cold/fatigue to reduce recurrence. No specific prophylaxis; HSV vaccines experimental; acyclovir preventive; condoms reduce transmission (not during active lesions).

Department to Visit
