Precancerous cells (cervical intraepithelial neoplasia) that would lead to cancer and early-stage cervical cancer (IA1) can be treated effectively by various surgical techniques. Surgical treatment methods include excision, where a cone-shaped portion of the cervix is removed, and ablation which removes only the parts with abnormal tissues.
The diagnosis is based on tissue examination, e.g. biopsy. [citation needed]Under the microscope, glassy cell carcinoma tumours are composed of cells with a glass-like cytoplasm, typically associated with an inflammatory infiltrate abundant in eosinophils and very mitotically active.
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.
It resembles small-cell cancer of the lungs and accounts for less than 3% of all cervical cancers. Like small-cell cancer in the lungs, the lymph nodes play a major role in spreading the cancer throughout the body. SCC begins in the inner part of the cervix and is very hard to diagnose.
Main histopathology features of squamous-cell carcinoma. Squamous-cell carcinoma (SCC), also known as epidermoid carcinoma, comprises a number of different types of cancer that begin in squamous cells. [1] These cells form on the surface of the skin, on the lining of hollow organs in the body, and on the lining of the respiratory and digestive ...
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 ...
Villoglandular adenocarcinoma of the cervix is a rare type of cervical cancer that, in relation to other cervical cancers, is typically found in younger women and has a better prognosis. [1] A similar lesion, villoglandular adenocarcinoma of the endometrium, may arise from the inner lining of the uterus, the endometrium. [2]
Cancer is a group of diseases involving abnormal cell growth with the potential to invade or spread to other parts of the body. [3] [4] Cancer can be difficult to diagnose because its signs and symptoms are often nonspecific, meaning they may be general phenomena that do not point directly to a specific disease process.
