Anti-Ethernano Tumor

An Anti-Ethernano Tumor is an malignant mass a mage can develop by overheating their magic core.

Cause
The tumor is created when a mage undergoes extreme stress to their body. After draining their core and overheating it, the tumor if formed.

Symptoms
The mage may not feel effects of the tumor right away, almost to the point where it happens in an instant. The mage afflicted then passes out, and their heartbeat slows down to the point it is nonexistent. If untreated, the tumor will kill the afflicted mage.

Cures
The first cure is immediate surgery. However due to the complex nature of the tumor, no doctor on Ishgar is capable of curing it, as confirmed by Porlyusica. An alternative however is to use mass manipulation magic on the inflicted area.
