Can a keratosis become cancerous?
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.
How long does it take for actinic keratosis to become cancerous?
In summary, of the estimated 10% of AKs that will develop into an SCC, the progression will take approximately 2 years.
Is keratosis benign or malignant?
Seborrheic keratoses are epidermal skin tumors that commonly present in adult and elderly patients. They are benign skin lesions and often do not require treatment. However, it is essential to be able to differentiate these lesions from other benign and malignant skin tumors.
Can seborrheic keratosis turn malignant?
Malignant tumour development within a seborrheic keratosis (SK) is extremely rare. Though the most commonly developed malignant tumour is the basal cell carcinoma (BCC), other tumour types have also been reported in literature.
Should keratosis be removed?
