A precancerous condition is a condition, tumor or lesion involving abnormal cells which are associated with an increased risk of developing into cancer. [1] [2] [3] Clinically, precancerous conditions encompass a variety of abnormal tissues with an increased risk of developing into cancer.
EIN lesions demonstrate all of the behaviors and characteristics of a premalignant, or precancerous, lesion. Precancer Features of EIN (Table I). The cells of an EIN lesion are genetically different than normal and malignant tissues, and have a distinctive appearance under the light microscope.
Cancer cells are cells that divide continually, forming solid tumors or flooding the blood or lymph with abnormal cells. Cell division is a normal process used by the body for growth and repair. A parent cell divides to form two daughter cells, and these daughter cells are used to build new tissue or to replace cells that have died because of ...
Dysplasia is the earliest form of precancerous lesion recognizable in a biopsy. Dysplasia can be low-grade or high-grade. High-grade dysplasia may also be referred to as carcinoma in situ. Invasive carcinoma, usually simply called cancer, has the potential to invade and spread to surrounding tissues and structures, and may eventually be lethal.
Cervical intraepithelial neoplasia (CIN), also known as cervical dysplasia, is the abnormal growth of cells on the surface of the cervix that could potentially lead to cervical cancer. [1] More specifically, CIN refers to the potentially precancerous transformation of cells of the cervix.
LeAnn Rimes took to social media to reveal that she had undergone surgery to remove precancerous cells. “January is usually a challenging month for me. Over the past couple of years, I’ve ...
People can have benign or malignant tumors, but there are also tumors that show characteristics of cancer but aren’t yet cancerous, says Dr. Brian Slomovitz, director of gynecologic oncology at ...
Dysplasia (change in cell or tissue phenotype) Hyperplasia (proliferation of cells) Hypoplasia (congenital below-average number of cells, especially when inadequate) Metaplasia (conversion in cell type) Neoplasia (abnormal proliferation) Prosoplasia (development of new cell function) Abiotrophy (loss in vitality of organ or tissue)
