Verified step by step guidance

Understand that epithelial tissues are one of the four basic types of tissues in the body, and they cover surfaces, line cavities, and form glands.

Recognize that a key characteristic of epithelial tissues is their high rate of cell division, which is necessary for their functions such as protection, absorption, and secretion.

Consider that the frequent cell division in epithelial tissues increases the likelihood of mutations during DNA replication, which can lead to cancer if the mutations affect genes that control cell growth and division.

Note that while other characteristics of epithelial tissues, such as polarity, avascularity, and support by connective tissue, are important for their function, they do not directly contribute to the development of cancer.

Conclude that the characteristic of epithelial tissues that makes them prone to cancer is their regular and rapid cell division, which increases the chance of accumulating genetic mutations that can lead to cancerous growths.
