Here's Buffalo Bills superfan Victor Neilson celebrating his victory over cancer in the most Bills way possible ... BY SMASHING THROUGH A TABLE!!!

BILLS MAFIA 4 LIFE, BABY!!!

42-year-old Nelson (who works in restaurant food supply) had just wrapped up 5 months of "intense chemotherapy" for Non-Hodgkins Lymphoma at the Vanderbilt-Ingram Cancer Center in Nashville. Nelson tells us he had a "baseball-size mass against my aorta."

So, after ringing the famous victory bell, Nelson took his celebration to another level!

Nelson strapped on his Bills helmet, his Tremaine Edmunds jersey and a pair of Zubaz pants -- and took out a folding table LIKE A CHAMPION!!

"Through all the prayers and support, I have prevailed," Nelson posted after the table-smashing.

I am" officially cancer-free. Thanks to all for the prayers and support. Couldn’t have done it without you. GO BILLS, BEAT THEM CHIEFS!!"

Check out all of the nurses, doctors and other staff on hand to help Vic celebrate -- it's awesome!

Nelson says he hopes the video will inspire others who are fighting cancer -- and now he's raising money for Vanderbilt Oncology in Nashville via his GoFundMe page.
