A man in Oklahoma City claimed he had to delay his treatment for brain cancer after his chemotherapy medication was stolen from his front porch Saturday.

James Mills, 43, was supposed to receive his planned round of chemotherapy Monday but was unable to do so after a hooded thief stole the potentially life-saving drug immediately after it was delivered by the United Parcel Service (UPS).

“We received a notification that my chemotherapy medication had been delivered from UPS. I checked the door and didn’t see the package. I double checked and they said it had been delivered," Mills told Oklahoma News 4 on Sunday. "I check the security cameras, and I saw the UPS driver deliver it, then about eight minutes later another individual comes up grabs it and takes off.”

Although the suspect has not been caught yet, Mills said that from the security footage, recorded by the cameras on both sides of the porch, it was clear that the thief knew what he was doing as he wore a hood and kept his head down so as to not get his face identified by the surveillance devices. The cancer patient added that he had no idea if he was going to get a replacement dose for his scheduled treatment.

"I mean, it's absolutely essential. I'm in a clinical trial where everything has to be taken at a certain time. A certain dose at a certain time, and I'm scheduled to start that tomorrow [Monday]," Mills said. "So, hopefully I can get a replacement before I get too far out of range."

"The pharmacy is closed because it's the weekend, so I'm going to have to try and get a hold of them first thing in the morning. See what can be done. It's pretty expensive medication as well. We'll have to find out what the procedure is to get [a] replacement,” he added.

The medication without insurance assistance was worth $30,000. Although he filed a report with Oklahoma City police regarding the theft, there was no guarantee if Mills would be able to get the dosage back – a fact that was not lost on his wife, Heather.

“It was frustrating, I was pretty angry. It’s not easy, I mean, we had trouble getting that medicine to begin with. Having to call the pharmacy, go through the doctor to get approvals and things like that. That in itself is frustrating," she said. "Of all the thing that could have been taken. All of the packages we receive that could have been taken, it had to be his medication."
