Large-cell carcinoma (LCC), like small-cell carcinoma (SCC) is very rare and only accounts for about 5% of all cervical cancers. Early-stage LCC are extremely aggressive and difficult to diagnose due to the sub-mucosal location of the tumor and intact overlying mucosa. As with SCC, in LCC early cases are asymptomatic.

Small-cell lung carcinoma (SCLC) has long been divided into two clinicopathological stages, termed limited stage (LS) and extensive stage (ES). [8] The stage is generally determined by the presence or absence of metastases, whether or not the tumor appears limited to the thorax, and whether or not the entire tumor burden within the chest can feasibly be encompassed within a single radiotherapy ...
[8] [7] Cancer that has spread from the colon, bladder, and stomach is far more common than cancer that originates in the vagina itself. [9] Some benign tumors may later progress to become malignant tumors, such as vaginal cancers. [10] [11] Some neoplastic growths of the vagina are sufficiently rare as to be only described in case studies. [3]
Cervical cancer typically develops from precancerous changes called cervical intraepithelial neoplasia over 10 to 20 years. [3] About 90% of cervical cancer cases are squamous cell carcinomas, 10% are adenocarcinoma, and a small number are other types. [4] Diagnosis is typically by cervical screening followed by a biopsy. [2]
In the late 1960s through 1971 a cluster of young women, from their teens into their twenties, was mysteriously diagnosed with clear-cell adenocarcinoma (CCA), a cancer not generally found in women until after menopause. Doctors at Massachusetts General Hospital eventually linked DES exposure before birth to the development of CCA in these ...
Vaginal cancer is an extraordinarily rare form of cancer that develops in the tissue of the vagina. [1] Primary vaginal cancer originates from the vaginal tissue – most frequently squamous cell carcinoma, but primary vaginal adenocarcinoma, sarcoma, and melanoma have also been reported [2] – while secondary vaginal cancer involves the metastasis of a cancer that originated in a different ...
The cause of CIN is chronic infection of the cervix with HPV, especially infection with high-risk HPV types 16 or 18. It is thought that the high-risk HPV infections have the ability to inactivate tumor suppressor genes such as the p53 gene and the RB gene, thus allowing the infected cells to grow unchecked and accumulate successive mutations, eventually leading to cancer.
