Hello mam, thanks for trusting health care magic.
im sorry to tell you that your doctor is absolutely right and that only trearment for dermoid
is surgery and also in your case it is already increasing in size..
but laparoscopic removal will make it really comfortable for you and also minimal scars
In case you have further questions you can consult me on health care magic forum and i will be happy to help
Take care and wish you all the best.
Dr Manisha Jain.
