The tumor doctors call the most extreme and complicated theyโ€™ve ever seen is finally gone from Lucas McCulleyโ€™s face.

โ€œIโ€™m amazed by the results,โ€ McCulley, who lives in Boise, Idaho, told TODAY. โ€œItโ€™s life-changing.โ€

It took more than seven hours of surgery at the New York Eye and Ear Infirmary of Mount Sinai last fall to remove the mass โ€” the 25th operation McCulley has endured in his life. He went public with the results on Monday, showing off a face thatโ€™s much lighter and pain-free.
