Epithelial cells are rapidly dividing, and are more exposed to carcinogens like UV radiations, and environmental toxins than other tissues in the body as epithelial cells line the surface of the body. Cells which reproduce frequently are more prone to become cancerous than other tissues.
Non-squamous cells, including transitional epithelial cells, are not necessarily indicative of cancer. Transitional epithelial cells are typically found in the urinary tract and can appear in urine samples without suggesting malignancy. However, if there is an unusual number or atypical features in these cells, further investigation may be warranted to rule out cancer or other conditions. A definitive diagnosis would require additional testing, such as a biopsy or imaging studies.
adenoma: A benign epithelial tumor having a glandular origin and structure.
A carcinoma is a malignant growth made of epithelial cells and tend to move into surrounding tissues. There are many many types of carcinomas.
Cytology is the study of cells shed from the epithelial surface. This branch of biology focuses on the structure, function, and behavior of individual cells to understand their role in the body's physiology and pathology. Cytology is commonly used in medical diagnostics, such as Pap smears for cervical cancer screening.

No, melanoma is skin cancer derived from melanocytes. Non-melanoma skin cancer is a malignant growth of the external surface or epithelial layer of the skin.
Epithelial tissue is the most common site for skin cancer because it forms the outermost layer of the skin, where it is directly exposed to environmental factors such as UV radiation, chemicals, and pathogens. This exposure can lead to DNA damage in the epithelial cells, increasing the risk of mutations that result in cancer. Additionally, epithelial cells have a high rate of turnover and division, which can further contribute to the likelihood of malignant transformations. Consequently, skin cancers, such as basal cell carcinoma and squamous cell carcinoma, often originate in this tissue.

Carcinoma is a type of cancer that starts in the epithelial cells. This type of cancer starts in a tissue that lines the surfaces of the body.
