[|AI|]  Thanks for your question on Chat Doctor. I can understand your concern. Possibility of brain cancer is very, very rare in your case because of your age. Brain tumors are common in child Chat Doctor.  So at your age of 19 years, no need to worry about brain tumor. Possibility of benign tumors like lipoma or sebaceous cyst or Desmond cyst is more in your case. So better to get done clinical examination of swelling and ultrasound examination of swelling for the diagnosis. You may need surgical removal of the swelling. Usually brain tumor causes constant headache, vomiting, difficulty in vision, unconsciousness etc. All these are absent in your case, so don't worry about brain tumor. You are mostly having benign skin tumor. Hope I have solved your query. Wish you good health. Thanks.
