What is a premalignant lesion?

What is a premalignant lesion?

Basically, a precancerous lesion is a collection of cells from the body’s organs that may look and appear to be the same as cancer cells, but may not have the properties of cancer cells that allow them to break through the membranes of the organ they come from and spread (or “metastasize”) to other organs.

What is meant by premalignant?

Listen to pronunciation. (pree-muh-LIG-nunt) A term used to describe a condition that may (or is likely to) become cancer. Also called precancerous.

What is the difference between premalignant lesion and condition?

a precancerous lesion is ‘a morphologically altered tissue in which oral cancer is more likely to occur than in its apparently normal counterpart’; a precancerous condition is ‘a generalized state associated with a significantly increased risk of cancer’.

What lesion is most commonly considered premalignant?

(1) Leukoplakia and erythroplakia are two clinical lesions widely considered to be premalignant.

What is the name for precancerous cells?

The word “dysplasia” is often used synonymously with precancerous cells, yet there are a few differences. When healthcare providers speak of dysplasia, they are speaking of abnormal cells that could become cancerous.

What are precancerous lesions called?

It’s also known as a solar keratosis. Actinic keratoses are very common, and many people have them. They are caused by ultraviolet (UV) damage to the skin. Some actinic keratoses can turn into squamous cell skin cancer. Because of this, the lesions are often called precancer.

WHO classification premalignant lesions?

Under the widely used World Health Organization (WHO) classification for the pathological diagnosis of oral premalignant lesions, dysplasia, which is graded as mild, moderate or severe, and carcinoma in situ (CIS), which is a non-invasive carcinoma, are classified as precursor lesions of oral squamous cell carcinoma.

Is it necessary to remove a premalignant oral lesion?

Premalignant Oral Lesions. Surgical removal of a premalignant lesion may or may not be warranted. Regardless of removal, periodic close follow-up of the patient for any visual changes to the lesion site is critical because lesions can recur and transformation into a malignant lesion is possible at anytime.

How is premalignant tissue used in cancer treatment?

Appropriate clinical and laboratory studies are designed to detect premalignant tissue while it is still in a premalignant stage. A battery of techniques are available to remove or kill the tissue, thereby preventing the development of cancer. The proper treatment method depends on the particular premalignant tissue involved.
