Meaning of Sebaceous

If the term ‘sebaceous’ sounds familiar to you, it may be because of the numerous times you heard it in your teen years as you were learning more about acne and the oils in your skin. As long as these cysts are little and blocked from the outdoors air, it’s fine for them to be left alone. They’re harmless. Usually in the starting stage they remain white, raised and small. When touched, your dog’s cyst will seem like a little, circular or oval bump beneath the skin. They are very common with dogs, and are also called epidermoid cysts, epidermal addition cysts, skin cysts and wens. Normally your dog will neglect it and set about his or her daily life as if it wasn’t there, and it will gradually get smaller up until it goes away totally. If the cyst does not bother your dog, you may consider leaving it alone and waiting for it to recover by itself.
