Is conjunctival intraepithelial neoplasia cancer?
Conjunctival intraepithelial neoplasia (CIN) is the most common conjunctival malignancy in the United States. It occurs in exposed areas of the bulbar conjunctiva with frequent involvement of the adjacent corneal epithelium.
What causes conjunctival intraepithelial neoplasia?
Conjunctival intraepithelial neoplasia (CIN) is non- invasive by definition; the basement membrane remains intact and the underlying substantia propria is spared. It is a slow- growing tumor that arises from a single mutated cell on the ocular surface.
What is conjunctival intraepithelial neoplasia?
Background: Conjunctival intraepithelial neoplasia (CIN) is the most common tumor of the ocular surface and is a precursor to invasive squamous cell carcinoma. CIN comprises a spectrum of premalignant epithelial neoplasia that usually begins near the limbus and spreads to the cornea.

How aggressive is urothelial carcinoma?
Muscle-invasive urothelial carcinomas are highly aggressive compared to cancers of the upper urinary tract, carrying a five-year disease-specific survival rate of <50% in pT2/pT3 disease, and this survival rate drops below 10% in pT4 cancer.
How fast does eye cancer spread?
There is no known cause, though incidence is highest among people with lighter skin and blue eyes. Approximately 50% of patients with OM will develop metastases by 10 to 15 years after diagnosis (a small percentage of people will develop metastases even later i.e. 20-25 years after their initial diagnosis).
