Invasive Carcinoma (Cervical)

Invasive carcinoma of the cervix is a type of cancer that starts in the cells of the cervix, which is the lower part of the uterus connecting to the vagina. This cancer affects the female reproductive system and can spread to nearby tissues and organs if not treated. It often develops slowly from precancerous changes caused by persistent infection with high-risk human papillomavirus (HPV) types. Symptoms may include abnormal vaginal bleeding, pelvic pain, or pain during intercourse, but early stages can be symptom-free. The disease can impact overall health by interfering with normal reproductive and urinary functions and may become life-threatening if it spreads to distant sites.

Invasive carcinoma of the cervix is a malignant neoplasm arising from the transformation of cervical epithelial cells, most commonly squamous cells, due to persistent infection with high-risk HPV strains such as HPV 16 and 18. The hallmark is invasion beyond the basement membrane into the cervical stroma, distinguishing it from carcinoma in situ. It is a major cause of morbidity and mortality worldwide, particularly in women with limited access to screening. The disease progression involves disruption of normal cell cycle regulation by viral oncoproteins E6 and E7, leading to uncontrolled proliferation and potential metastasis. Clinically, it presents with symptoms like abnormal vaginal bleeding, pelvic pain, or discharge, but may be asymptomatic in early stages. Diagnosis and staging are critical for guiding treatment and prognosis.
