Premalignant lesions are morphologically atypical tissue which appear abnormal when viewed under the microscope, and which are more likely to progress to cancer than normal tissue. [7] Precancerous conditions and lesions affect a variety of organ systems, including the skin, oral cavity, stomach, colon, lung, and hematological system.
Actinic keratosis, pre-cancerous area of thick, scaly, or crusty skin (Below) with cutaneous horn tissue (above) Cutaneous horns , also known by the Latin name cornu cutaneum , are unusual keratinous skin tumors with the appearance of horns, or sometimes of wood or coral.

Ductal carcinoma in situ (DCIS), also known as intraductal carcinoma, is a pre-cancerous or non-invasive cancerous lesion of the breast. [1] [2] DCIS is classified as Stage 0. [3] It rarely produces symptoms or a breast lump that can be felt, typically being detected through screening mammography.
A cancerous tumor (or "solid tumor" in the jargon of oncologists to differentiate them from hematological malignancies) is an organ consisting of two tissues: in the center the cancerous tumor proper and around the ExtraCellular Matrix (ECM), sometimes called stroma, chorion or connective tissue. The concept of connective tissue is interesting ...
Lobular neoplasia is considered pre-cancerous, and LCIS is an indicator (marker) for increased risk of developing invasive breast cancer in women. This risk extends more than 20 years. Most of the risk relates to subsequent invasive ductal carcinoma rather than to invasive lobular carcinoma. [4]
It is a precancerous lesion, a tissue alteration in which cancer is more likely to develop. [4] The chance of cancer formation depends on the type, with between 3–15% of localized leukoplakia and 70–100% of proliferative leukoplakia developing into squamous cell carcinoma .
The cells in tubular adenomas, like most tumors that frequently progress to cancer, show certain abnormalities of cell maturation and appearance collectively known as dysplasia. These cellular abnormalities are not seen in benign tumors that rarely or never turn cancerous, but are seen in other pre-cancerous tissue abnormalities which do not ...
