I was diagnosed with a small AN 12 mm x 10 mm over 10 years ago. I had three MRIs within the first six months and two of the MRI's were slightly different measurements. One radiologist said it had "grown" slightly, but then when I had a second opinion on the reading, the doctor and radiologist actually checked the size of the first MRI, the second and the third and they were all the same size, no change. I was told it was different radiologists reading these MRIs. The AN measurements are so tiny when you talk about the difference between 9 mm and 7 mm it is so miniscule a measurement it could barely be called "growth" even if there had really been any growth. I would have another radiologist or another neurotologist check your MRIs and confirm that you may not have any growth, and if you do, it is minimal. These tumors are extremely slow-growing, unless you have NF-2, and if not the growth in rarely rapid. Your AN is very small, years ago would not have been even diagnosed because the technology was not detailed enough to see it. Now they are discovering tiny ANs which are not causing problems, are not malignant and can be left with minimal side effects from the actual tumor. Removal of such a smal benign tumor makes no sense, even radiation at this point is not necessary.
My AN has not changed in 10 years, it is still 12 mm x 10 mm. I have the same hearing I had 10 years ago, and surgery and radiosurgery will rarely stop any hearing loss which may be occurring. Some are lucky to still have good hearing, and others may lose some or all. Hearing loss is not relevant to size of the tumor, some with tiny ones can have hearing damage, and others with large ones have not much hearing loss.
I hope I am not offending anyone in the wait and watch area or those considering treatment, but 10 years ago when I refused treatment to "wait and watch" it was a new concept. Now my neurotologist has over 45 patients with ANs who are waiting and watching, and not many having any growth. In 1997 those of us who stood our ground to do nothing have created a whole new group of wait and watchers, and many have needed no treatment.
Good luck with your decision, but please do not panic over the "growth" concept as quite often it can be the reading of the MRI that is a little "off." Wait another six months, have another MRI and have the same radiologist read them all and tell you if there really is any growth.
