Hello; Hello; Though i don t doubt the diagnosis made by your doctor as he would be in a better position to assess the condition of your child than me, But Still I would like to say. True sebaceous cysts are relatively rare and are known as steatocystomas, Symptoms: Skin redness, Tender or sore skin, Warm skin in the affected area. You should get her evaluated once for her complaint to get her examined physically by a Dermatologist.(Diagnosis purpose) If you are worried about cancer etc you can go for a biopsy to rule out other conditions. I would advise: If it is Sebaceous cysts 1.Sebaceous cysts are not dangerous and can usually be ignored. 2.Surgical excision of a sebaceous cyst is a simple procedure to completely remove. Home Remedies: If it is sebaceous cysts 1.Another method of treatment involves placement of a heating pad directly on the cyst for about fifteen minutes, twice daily, for about 10 days (depending on size and location of the cyst) to promote drainage 2.Apple cider vinegar, Potassium Iodide, Dimethyl sulfoxide (DMSO)- Basically, the DMSO carries Iodide into the skin, and the iodide itself eats up fatty material like the cyst. I hope I have answered your query to your satisfaction. Wishing your child a speedy recovery. Thanks; Regards; Dr Sagar Mhatre
