Here is the link to the waiver guide. The following is what I found on neurological tumors, but it does not make mention of brain tumors that have been removed:
CONDITION:
Neurological Tumors
I. Overview.
Primary tumors arising from within the meninges or the parenchyma of the brain and spinal cord are
common at all ages of life. Thirteen thousand new primary brain tumors were reported in 1993 in
the United States along with approximately 80,000 metastatic brain neoplasms. Spinal tumors are
only 25% as common as intracranial tumors. The most frequent location for all types of spinal
neoplasms is in the thoracic cord. In patients with brain tumors, headache is the initial symptom in
50% of patients and seizure is the initial symptom in 20% of patients.
II. Aeromedical Concerns.
Aeromedical concerns include: 1) seizures, 2) neurological impairment, 3) neuropsychological
impairment, and 4) risk of sudden neurological dysfunction (particularly in tumors of the spinal
cord).
III. Information Required for Waiver Submission.
Medical evaluation board (MEB) and tumor board recommendations, AFIP confirmation of the
histology and recent neurology consultation with supporting laboratory findings are required.
IV. Waiver Consideration.
Aircrew with tumors of the spinal cord may be granted a waiver provided there is no recurrence and
neurological sequelae are acceptable 5 years after therapy. Waiver may be granted for tumors of the
peripheral nervous system if there is no appreciable impairment of function. All tumors involving
the brain or meninges are disqualifying. The ACS has evaluated three individuals with tumors of
the peripheral nervous system. Two evaluees were diagnosed with Schwannomas of the lumbar
cord nerve roots and were granted waivers. The third evaluee was diagnosed with a neurilemmoma
of the left C6 cranial nerve root with a residual Horner's syndrome status post excision and was
granted a waiver. The ACS has evaluated four individuals with tumors of the central nervous
system other than acoustic neuromas. There were no waivers granted.
