Question: I am a 24 year old who has always aspired to become a pilot. I've decided to eventually get a private pilot's license so I can fly just for fun. However, a few months ago I was diagnosed with brain tumor which I had removed. There were no complications, I have never had any seizures, I'm not epileptic, etc. As far as I am concerned (and my doctors as well), I am now in perfect health.

With this in mind, is it still possible for me to obtain a PPL?

Answer: 
According to [AOPA](http://www.aopa.org/)'s medical guru on their discussion board (members only, or I would link to an example) it is possible to get a medical certificate following a tumor removal but only after a 5-year wait and a battery of tests.

But having said that, medical issues are very individual and the FAA's [AME guidance](http://www.faa.gov/about/office_org/headquarters_offices/avs/offices/aam/ame/guide/app_process/exam_tech/item46/amd/cd/) suggests that one year is enough in some cases. In the end the only way to get a definite answer is to find a good AME who can review your case in detail and advise you. Note that standard advice is to schedule a consultation first, rather than go straight for the actual flight medical.

Disclaimer: I'm not a doctor or AME and I have no idea how brains work :-)
I have a PPL license and I was on the way to obtain a CPL license when I had a seizure.  

After many tests it came out that I had a cavernous angioma in my brain on the left temporal lobe anterior. It had bleed outside causing the seizure. 
After removal of the cavernoma with brain incision, I had no other seizures and no complications and I went to see the AME. 
I had lots of EEGs, MRIs and the AMEs decision is giving back my Class I certificate for at least 1 year after the surgery.
Neurology is decreasing the medication now and after medication is finished I will have few other checks. 
If everything goes OK, I will have my Class I medical license back with an OML restriction (most probably).

I hope this helps and don't give up. :)

Note : I have my Class 1 with OML and CPL(A) now.
