Cervical cancer: This is the most likely diagnosis due to the description of the mass as friable, which suggests a tumor that is likely to bleed easily, a characteristic often associated with malignant neoplasms, particularly in the context of cervical cancer.

Cervical polyp: Although less likely than cancer, a polyp could present as a friable mass, especially if it becomes necrotic or infected.
Cervicitis: Inflammation of the cervix could lead to a friable appearance, especially if there is significant ulceration or infection.
Metastatic disease: Other cancers can metastasize to the cervix, presenting as a friable mass, though this is less common.

Invasive placental tissue (e.g., placenta accreta) in pregnancy: Although rare, this condition can present with a friable cervical mass and is critical to diagnose due to its potential for severe bleeding and complications in pregnancy.
Gestational trophoblastic disease: This includes conditions like choriocarcinoma, which can present with a friable mass and has significant implications for both mother and fetus if not promptly diagnosed and treated.

Cervical lymphoma: Primary lymphoma of the cervix is rare but can present as a friable mass.
Cervical melanoma: Although extremely rare, melanoma can occur in the cervix and may present as a friable, pigmented mass.
Carcinosarcoma: A rare malignant tumor that contains both carcinoma and sarcoma elements, which could present as a friable cervical mass.
Leiomyosarcoma: A rare smooth muscle tumor that could present in the cervix, though more commonly found in the uterus.
