Peter Czerwinski, best-known by his online moniker Furious Pete, has earned his millions of followers (2.1 million YouTube subscribers, to be exact) through a unique amalgamation of eating challenges and fitness videos. Becoming a YouTube sensation largely through videos such as his behind-the-scenes tricks for before and after photos, and his Furious World Tour, Czerwinski's true story is one that includes many trials in a short period of time.

Anorexia. Simultaneous hospitalization of both parents. Cancer.

His unusual journey is succinctly displayed on this page dedicated to his competitive eating career, with an accompanying full-length documentary about his life. He is very open about his personal matters — something that carries over into his YouTube channel and the many videos he uploads on a weekly basis.

Today, news came in the form of a Furious Pete video void of the usual enthusiasm and vigor viewers are accustomed to with Czerwinski.

Czerwinsky's announcement that his cancer has returned is difficult news for his many fans, who will certainly provide support during the trials to come.

In the video, Czerwinsky shares a link to a vlog where he will regularly detail his time spent on radiation and the physical challenges of battling with cancer.
