Precancerous cells, or premalignant cells, refer to abnormal cells that can transform into cancerous cells; however, they are not invasive, meaning they don’t spread to other body parts, explains About.com. In most cases, precancerous cells remain abnormal but do not develop into cancer.
Common treatment options for precancerous cells include cryosurgery, laser surgery and conization. Another form of treatment for precancerous conditions that occur along the epidermis involves the use of topical medication, such as creams and lotions, as stated by the American Society of Clinical On
A precancerous condition is defined as a medical condition that is not yet cancerous, but it may become a cancer if left untreated, according to MedicineNet. Another word for precancerous is premalignant.
The growth of precancerous cells on the cervix, or cervical dysplasia, indicates that abnormal cells have developed on the cervix, according to the University of Maryland Medical Center. Cervical dysplasia is separated into low-grade and high-grade categories based on the extent of abnormal cell gro
Symptoms of precancerous lesions include persistent scaly patches frequently on the scalp or lip, small horn-shaped growths, and moles that are oddly colored, oddly shaped or changing. Precancerous lesions are identified by WebMD as abnormalities in skin cells that may become cancer.
Polyps are extra pieces of tissue growing from the lining of the colon, says the National Digestive Diseases Information Clearinghouse. Polyps can stick out into the colon and look somewhat similar to mushrooms, or they can lie flat against the wall of the colon. Colon and rectal cancer usually begi
Precancerous polyps are treated by removing tissue samples, determining the type of polyp in the laboratory, and periodic monitoring, according to WebMD. Polyps are benign tissue growths that appear on the wall of the colon that may develop into cancer, explains the American Cancer Society.
A benign tumor is a mass of cells caused by abnormal cell growth that is not associated with cancer. Unlike cancerous tumors, benign tumors do not spread or move to other parts of the body, according to WebMD.
According to the National Cancer Institute, the primary difference between benign and malignant tumors is that malignant tumors are cancerous, while benign tumors are not. Only malignant tumors are able to spread to nearby tissue, enter the bloodstream and expand to other areas.
Benign moles often appear during the first decades of life and are characterized as round or regular shaped and brown, reports the Skin Cancer Foundation. On the other hand, melanoma is often irregularly shaped, may not be pigmented and frequently changes in size, color and appearance over time.
