[|Human|] It has been requested that I go in for a vision field test after my eye exam this morning.  Several things were listed for diagnosis.  One of them being the optic neuritis.  Im really scared at the moment and dont know how to react or what to do.  I have that test in 3 days.  However, I was wondering, if a brain tumor, how fast do tumors typically grow?  If malignant, is it months, years, weeks or what that is considered rapid growing?  What time frame is considered slow-growing?
[|AI|]  Hi, Thanks for writing in to us. Optic neuritis is an inflammation of the optic nerve which carries impulses from the eye to the brain through the optic tract. This is usually a limited condition and is treated with steroids. Brain tumors are of many types and categories. Most benign tumors grow very slowly and stay stable for years before they cause symptoms. In contrast, malignant or cancerous tumors grow violently, and it might take 3 to 6 months for them to grow into a mass of cancer cells. In conclusion, a tumor is slow growing if it takes more than a year or two to double its size and is a fast-growing it there is double in tumor volume over 3 to 6 months. You likely do not have a brain tumor.
