Hearing that the doctor has found a tumor is a person's worst nightmare. Hearing that said tumor is the size of a Buick? Forget about it. Body-Philosophy has searched far and wide to find the largest, meanest, and most mind-boggling tumors known to mankind. We're talking masses that weigh more than the Olsen twins combined. Oh, and if you're a squeamish hypochondriac, you may want to skip this one.

The 300 Pound Tumor

Trying to lose weight? Watch this YouTube video before lunch and we guarantee you won't be hungry. The video shows a 1991 surgery in which the world's largest intact tumor, a whopping 303-pounder, was removed from an unnamed 34-year-old female patient's abdomen.

The 300 Pound Tumor (Cont'd)

According to Apatheticaphid.wordpress.com, the mass measured three feet in diameter and left on a stretcher after six hours of surgery performed by Professor Katherine O'Hanlan of Stanford University Medical Center in California.

China's Huang Chuncai made international headlines - and earned the nickname "Elephant Man" - when the 31-year-old man had a 33-pound tumor removed from his face earlier this year.

Writes Forbes, "Huang Chuncai's facial tumor became noticeable when he was 4 years old, the hospital said. It grew bigger and more quickly as he grew older, blocking his left eye, pushing his left ear to shoulder level, knocking out his teeth and deforming his backbone."

Not surprisingly, Chuncai had difficulty eating, speaking, and hearing because of the tumor.

It's not often that a Chicago surgeon - in this case Dr. McKay McKinnon, who also removed Lori Hoogewind's 200-pound tumor - travels to Romania for a patient. Dr. McKinnon and anesthesiologist Dr. Lynn Kahana made the trip in 2004 to treat Lucica Bunghez, a then-47-year-old Romanian woman with a 176-pound tumor caused by neurofibroma, a disorder which causes tumors to develop on the skin, tissues, and bone. The tumor was wrapped around Bunghez's body, covering her back and most of her thighs.

According to CBSNews.com, Bunghez weighed just 88 pounds without the tumor, which took eight hours to remove.

In 2004 Ohio resident Grace Radtke had the mother of all ovarian cysts removed - a 66-pound whopper "the size of three watermelons," NBC11.com reports. The tumor, which had wedged itself under Radtke's ribs, took four people to lift.

Strangely, whereas in other cases large tumors cause patients to experience a dramatic weight gain, 300-pound Radtke actually lost weight, which made her go to the doctor.

"It didn't feel normal," Radtke told FoxNews.com. "It was like a long pregnancy."

Imagine having Nicole Richie strapped to your abdomen, and you might understand what it was like for 32-year-old Oklahoman Kayla Hilton to walk around with a 93-pound ovarian cyst. Hilton had the fluid-filled cyst removed earlier this year, MSNBC.com reports.
"I feel lighter and happy to heal, to get better and be able to get around," Hilton said.

It took years for doctors to finally diagnose the cyst that had triggered a massive weight gain for Hilton, who weighed more than 500 pounds.

The story of John Lee Johnson reflects that these massive tumors can indeed be fatal. Last year Johnson, a noted civil rights activist from Illinois, passed away three months after surgery to remove a large 37-pound tumor from his abdomen, News-Gazette.com reports. The paper also reported that Johnson's tumor is believed to be the second-largest soft-tissue liposarcoma on record.

When 14-year-old Mona Lisa Howell's stomach suddenly ballooned up in 2002, her family feared that the Indiana teen was pregnant, Local6.com reports. Once doctors ruled that out, they diagnosed her as obese and in need of a diet. It wasn't until yet another doctor ordered an ultrasound and CAT scan that the real culprit was determined. Mona Lisa has a 37-pound cyst on her ovaries.

Doctors were able to remove the cyst, which was "the size of a beach ball." Side note to any pregnant teens out there: We don't think Mom and Dad will buy this as an excuse.
