A mucinous neoplasm (also called colloid neoplasm) is an abnormal and excessive growth of tissue with associated mucin (a fluid that sometimes resembles thyroid colloid). It arises from epithelial cells that line certain internal organs and skin, and produce mucin (the main component of mucus).
Phlegm is more related to disease than mucus, and can be troublesome for the individual to excrete from the body. Phlegm is a thick secretion in the airway during disease and inflammation. Phlegm usually contains mucus with virus, bacteria, other debris, and sloughed-off inflammatory cells.
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.

Chest congestion is usually caused by excess mucus in the airways, says Meilan King Han, M.D., M.S., professor of medicine and chief of the Division of Pulmonary and Critical Care at the ...
Cervical cancer nearly always involves human papillomavirus (HPV) infection. [45] [46] HPV is a virus with numerous strains, several of which predispose to precancerous changes in the cervical epithelium, particularly in the transformation zone, which is the most common area for cervical cancer to start. [47]
The mechanisms for penetration and bioactivity of the cervical mucus must be understood to utilize the mucus’s potential as a drug delivery system. [1] Due to the changes in viscosity and water content of the mucus during the stages of the menstrual cycle , this poses a particularly complex consideration. [ 3 ]
Cervical ectropion can be associated with excessive, non-purulent vaginal discharge due to the increased surface area of columnar epithelium containing mucus-secreting glands as well as intermenstrual bleeding (bleeding outside of regular menses). [1]
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.
