<s>[INST] I have no idea how I got this bump on my forehead, it is a size of a quarter and raised about 1/4 . I must of hit my head and did not think any thing of it and then one day I felt it. It has been at least 5 yrs. Is there anything naturally I can put on it to reduce it size? I would do it every day if I knew it would get rid of it. Thanks so much for your help. [/INST] Hi, Thanks for the query to Chat Doctor.-I studied your query in depth and understood your concerns.-Cause and Treatment-of the lump on forehead-is mostly due to Sebaceous cyst ? Or Epidermis tumor? Or Desmond tumor. Its benign tumor and harmless and not to be worried. Remedy-I would advise consulting a Surgeon and excise it for cosmetic worries if any. This would help you to plan treatment with your doctor.Don't worry and things will settle Hope this would resolve your query. Welcome further for any query in this regard.
