Seborrheic Keratosis (SK) is a common skin condition that appears as raised, tan or brown patches on your skin. They usually appear on the face, chest, back, and arms but can occur anywhere. Chevy Chase seborrheic keratosis varies in size and shape but is generally benign and does not require treatment.
However, they may be cosmetically displeasing and can be removed by your dermatologist if you choose to do so. You need to note that these growths are not cancerous; however, they can sometimes look similar to skin cancers, so it is best to have them checked out by your doctor if there is any cause for concern.
Your doctor will diagnose SK by doing a physical examination and may also use a biopsy to confirm the diagnosis. The earlier the diagnosis is made, the better your prognosis and treatment options may be.
Causes of seborrheic keratosis
These are some of the causes:
- Exposure to UV radiation from the sun: Did you know that prolonged exposure to UV radiation from the sun can increase your risk of developing SK?
- Genetics: It is believed that genetics may play a role in the development of SK. If you have a family history of this condition, you may be more likely to develop it yourself.
- Age: The most common age range for developing SK is between 40 and 70.
- Environmental factors: It is believed that certain environmental factors can increase your risk of developing SK, such as exposure to pollutants or chemicals.
Treatment options for seborrheic keratosis
Below is a detailed explanation of the treatment options:
Cryosurgery
Cryosurgery is a technique used to remove SK by freezing the growths with liquid nitrogen. It can be done in your doctor’s office and does not require stitches or bandages. The process entails applying liquid nitrogen to the SK, which causes it to blister and fall off in one or two weeks.
Curettage
Did you know that SK can also be removed using curettage? This is a technique in which your doctor will use a special tool to scrape off the SK. After this, the area may need to be cauterized or stitched up if the lesion is large.
Laser therapy
Laser therapy is another option for removing SK and can also lighten the skin around the area. The laser will target and destroy the SK, leaving healthy skin behind. This treatment is painless and does not require stitches or bandages.
Topical medications
Topical medications are sometimes prescribed to help reduce inflammation caused by SK. These topical creams can lighten the affected area and reduce itching or discomfort.
No matter which treatment you choose, always remember that SK can reappear even after being removed. This means you should take precautions to protect your skin from UV radiation exposure and limit exposure to environmental pollutants.
