Precancerous skin lesions, also classified as in situ carcinomas, refer to various skin lesions that can transform into invasive skin cancers. These lesions represent the early stages of epithelial skin tumors and show different clinical and histological manifestations on the skin or mucosa. The mai...
Precancerous skin growths are considered abnormal areas of the skin that could turn into cancer if they aren’t removed. Typically, these growths are found on the skin's surface and are generally located in areas regularly exposed to the sun, such as the head, back, shoulders, or hands....

Like many cancers, skin cancers -- including melanoma, basal cell carcinoma, and squamous cell carcinoma -- start as precancerous lesions. This WebMD slideshow tells you how to spot the early warning signs of skin cancer and seek treatment.
A study of 132 patients at Washington University (St. Louis) School of Medicine found that a combination of two topical drugs that have been in use for years triggered an immune response against precancerous skin lesions (actinic keratosis). The drugs are 5-fluororacil, which is a cream ver...
Precancerous skin growths develop on skin that has a lot of sun exposure over time without proper protection. While it’s not considered cancer yet, it can turn into it in the future. While many forms of precancerous skin growths can form after the age of 40, it can also happen...
A treatment previously shown to clear the precancerous skin lesions called actinic keratosis now appears to reduce the chance that the treated skin will develop squamous cell carcinomas (SCCs), the second most common form of skin cancer. In their paper b
the greater the amount of ultraviolet rays in a region, the more common skin cancer is; and Circled digit four in xeroderma pigmentosum, in which it is impossible to repair DNA damage caused by ultraviolet rays, skin cancer has a predilection for the areas of the skin that are exposed to ...
Precancerous lesions of the skin consist of (1) carcinomas in situ of the skin, (2) the local skin conditions that are going to develop skin cancers, and (3) the general conditions that are risks for developing skin cancers. Typical carcinomas in situ of the skin are senile (actinic)...
THE mast-cell reaction of the mouse skin, painted with tar or carcinogenic hydrocarbons, has been known for a long time 1 . According to several authors, these cells show a golden-brown fluorescence when examined under the microscope in ultra-violet light 2 , though other investigations give ...
