The cause of this is from the radiation simply cooking the artery and causing it to shrink. This combined with a slightly high cholesterol level caused a build up of placque in that area, causing the TIA. The remedy for this was to put a stent in that artery all the way up behind my ear, just before that artery reaches the brain.

Types of Radiation Therapy for Brain Tumors
There are 2 main types of therapy. You may get both types. They include:
External beam radiation therapy (EBRT)
There are several types of EBRT. The goal is to target the tumor and limit damage to nearby healthy brain cells. To limit the harm, your healthcare provider may use special types of EBRT such as:
Brachytherapy
For this treatment, the radiation is placed very close to or inside the tumor. This is done during surgery. The radiation the implants give off travels a very short distance. This helps limit the effect on nearby healthy tissue.
Brain Radiation Side Effects
Generally, side effects from radiation treatment are grouped into two categories:
Radiation necrosis
Sometimes dead brain tissue forms at the site of the radiation. This is called radiation necrosis. The mass of dead brain tissue comes from both cancer cells and healthy cells. Radiation necrosis can take anywhere from months to years to develop.
Risk of future cancer
Radiation can damage the DNA in healthy cells. As a result, you have a small risk of a second brain cancer after brain radiation. This second cancer usually occurs many years later. Talk to your radiation oncologist about the risks and benefits of radiation therapy.
The Radiation Team
