Et Tumor, Brute?

Et Tumor, Brute? is a quest in Fallout: New Vegas which involves removing Caesar's Brain Tumor.

Quick Summary
Caesar needs you to get the supplies to cure his headaches and remove his brain tumor. You will need to find a functional Diagnostic Scanning Module or buy a set of surgical tools (999 caps at the New Vegas Medical Clinic) and a Doctor's Bag to operate Ceaser manually (medicine skill level 75 is needed).

Detailed Summary
If you choose to find the Diagnostic Scanning Module, you must make your way towards the radiation and ghoul ridden Vault 34 (similar to Fallout 3's Vault 87). You can find the vault north of the NCR's Camp Golf or west of the NCR's Sharecropper Farms near New Vegas. It is recommended that you bring several Rad Away and RadX. You will notice the radiation right off the bat as the entrance is brimming with radiation. Due to the intense radiation, once entering the vault you'll find approximately 20-30 ghouls of various types inside.

Notable Loot
semi-automatic rifles, automatic rifles, sniper rifles, a block of C4, a mini gun, a rocket launcher, energy weapons, and grenade launchers. Most of this can be obtained in the Overseer's quarters. Accessing the Overseer's rooms requires 2 pass codes that you can get from 2 dead scientists, now Ghoulified, that can be found submerged inside the Vault.
