Seborrheic Keratosis Removal with Cryotherapy
We generally cringe at the blisteringly cold weather we have here in Ottawa, but in the case of treating benign or malignant skin lesions like seborrheic keratoses, cold temperatures just might be the solution you need. While cryotherapy is not a typical topic of conversation, it has become an increasingly popular treatment option over the years.
Cryotherapy is the local or general use of freezing temperatures in medical therapy. We offer localized treatments for unwanted skin lesions like seborrheic keratoses, so you can say goodbye to unwanted and unsightly skin growths.*
What is a Seborrheic Keratosis?
Seborrheic keratoses (also called a “seborrheic verruca” or “senile wart,”) are common benign (meaning non-cancerous) skin growths. They may resemble warts, moles, actinic keratoses, or skin cancer lesions, however they differ because they are non-cancerous and have no viral origins. Seborrheic keratoses start as small rough bumps and will slowly thicken and grow over time. These growths are usually brown or tan in colour, and are more common in middle-aged and older adults. It is more common for patients to develop multiple growths, however some only develop one. They are most commonly found on the face, neck, back, and arms – the parts of your body most frequently exposed to the sun’s harmful ultraviolet (UV) rays.
Treatment with Cryotherapy*
We start by applying freezing cold liquid nitrogen to the affected region, which works by targeting the abnormal cells in the skin in a controlled manner. This helps prevent those cells from reproducing and growing (aka cellular metabolism). It can also promote cellular survival while generally decreasing inflammation, pain, and spasms. If requested, a local anaesthetic can be applied to the affected area(s) of the skin for a numbing affect in order to minimize your discomfort. However, our clients rarely ask for this because the treatment is bearable for most individuals.*
The term cryotherapy most commonly refers to the specific surgical procedure called cryosurgery, which is what we do at our clinic. But, it also encompasses other types of cryogenic treatments.
Oftentimes, the lesion(s) will respond to one treatment, but in more severe cases, multiple sessions will be needed to acquire the full desired effect. While it may sound somewhat complicated, the procedure is quite simple and safe to perform as it doesn’t take very long nor are there very many side effects associated with it.*
