Which WWE Wrestler Has Leukemia?

The WWE community was shocked to hear the news that one of their own has leukemia. Here’s everything we know so far about the wrestler’s diagnosis.

WWE Wrestlers with Leukemia

The WWE is full of incredibly talented people who have overcome great odds to entertain fans around the world. Some of these wrestlers have had to battle leukemia, and have done so with courage and grace. In this article, we will take a look at some of the WWE wrestlers who have been diagnosed with leukemia.

Rey Mysterio

Rey Mysterio, real name Óscar Gutiérrez, is a Mexican-American professional wrestler who is currently signed to WWE. He is also a former member of the stable The Filthy Animals. Rey Mysterio’s first match was in 1989, when he was just 14 years old. He has since gone on to wrestle for some of the most prestigious wrestling organizations in the world, including WCW, ECW, and WWE.

In late 2019, it was revealed that Rey Mysterio had been diagnosed with leukemia. This came as a shock to many fans, as Rey Mysterio is only 45 years old. While there is no cure for leukemia, it is possible to put the disease into remission. It is unclear at this time what treatment Rey Mysterio is receiving or how his health is progressing.

Eddie Guerrero

Eddie Guerrero was an American professional wrestler who found success in World Championship Wrestling (WCW), Extreme Championship Wrestling (ECW), and World Wrestling Entertainment (WWE).
Guerrero held various championships within WWE, including the WWE Championship and the WWE United States Championship. He was also a one-time Intercontinental Champion, a two-time WWE Tag Team Champion, and a two-time WCW/World Champion. Guerrero’s gimmick was that of “Latino Heat”, a crafty, resourceful babyface wrestler who would do anything to win.
He debuted in ECW in 1995 as the “mysterious” Latino Causing Havoc; he feuded with Taz over the ECW Heavyweight Championship and left ECW with Chris Benoit to join WCW in January 1996. After losing a match to Dean Malenko for WCW’s Cruiserweight Championship at The Great American Bash 1996 due to interference by Malenko’s father, Hiroko, Guerrero became a fan favorite. He defeated Malenko for the title at Halloween Havoc later that year.
Guerrero left WCW in 2000 due to creative frustrations; he joined WWE after being invited by Stephanie McMahon. There, Guerrero gained notoriety as “Latino Heat”, culminating in his winning the WWE Championship from Brock Lesnar at No Way Out 2004 after Lesnar accidentally knocked out referee Earl Hebner while attempting Guerrero’s signature slingshot powerbomb maneuver on him. Guerrero subsequently won the match via pinfall with a small package.
In November 2005, Guerrero lost the WWE title due to interfering in John Cena’s match with Kurt Angle; as per the stipulation of the match, he was required to leave WWE for good if he failed to win the title.
Later that month at Survivor Series however, he returned under his real name as part of Team Angle against Team Cena; he pinned Chris Masters before being forced to submit to an ankle lock by Cena.
Cena retired Guerrero by pinning him following an FU; both men later named this match as their favorite encounter against each other.
Guerrero died on November 13, 2005 after suffering acute heart failure in Minnesota at age 38 due to underlying atherosclerosis aggravated by hypertension and his prior history of cocaine use…

Bret Hart

Bret “Hitman” Hart was born in Calgary, Alberta, Canada. He is the eldest son of Stu and Helen Hart. Growing up in the Hart wrestling household, Bret, along with his brothers and sisters, learned the values of hard work and dedication at an early age. Under the tutelage of their father, Bret and his siblings became highly skilled athletes. Bret is a multiple-time World Champion, having held WWE’s World Heavyweight Championship five times and WWE’s Intercontinental Championship twice. He is also a two-time WCW United States Heavyweight Champion, and a one-time WCW World Television Champion.

In 2010, Bret was inducted into the WWE Hall of Fame by his longtime friend “Superstar” Billy Graham. On January 13, 2010, Bret’s autobiography Hitman: My Real Life in the Cartoon World of Wrestling was released and became a New York Times Best Seller.

Causes of Leukemia in WWE Wrestlers

Leukemia is a type of cancer that affects the blood and bone marrow. The cause of leukemia is unknown, but research suggests that it may be caused by a combination of genetic and environmental factors. WWE wrestlers have a higher risk of developing leukemia due to the physical nature of their job.


There are many different types of leukemia, but the most common form of the disease in WWE wrestlers is acute lymphoblastic leukemia (ALL). This cancer affects the blood and bone marrow, and is most often diagnosed in children and young adults. However, it can also occur in older adults.

The cause of ALL is not fully understood, but it is thought to be due to a combination of genetic and environmental factors. Genetically, certain mutations (changes) in the DNA of blood cells can make them more likely to develop into leukemia. These mutations are usually inherited, but they can also occur spontaneously. Environmental factors that may increase the risk of developing ALL include exposure to certain chemicals (such as benzene) and ionizing radiation (such as X-rays).


One potential cause of leukemia in WWE wrestlers is their exposure to environmental toxins. While on the road and during matches, wrestlers are exposed to a variety of toxic substances, including pesticides, herbicides, and insecticides. In addition, they may be exposed to lead and other heavy metals through the use of equipment such as weights and dumbbells. All of these substances can potentially damage DNA and increase the risk of developing leukemia.


Leukemia is a cancer of the blood cells. WWE performer Roman Reigns recently announced that he has leukemia and has to step away from wrestling for now. This announcement brought up questions about what causes leukemia and if other WWE wrestlers have it.

Leukemia is caused by cells in the bone marrow (the spongy tissue inside bones where blood cells are made) growing out of control. The four main types of leukemia are acute lymphocytic leukemia (ALL), acute myeloid leukemia (AML), chronic lymphocytic leukemia (CLL), and chronic myeloid leukemia (CML).

There are many risk factors for developing leukemia, including lifestyle choices like smoking, being overweight, and exposure to certain chemicals. However, it’s important to remember that most people with these risk factors don’t get leukemia.

There is no definitive answer as to whether or not other WWE wrestlers have leukemia. While some performers have died from the disease, it’s possible that they contracted it after their time in the WWE. It’s also possible that some performers may be living with the disease but have not yet gone public with their diagnosis.

If you are concerned about your risk of developing leukemia, talk to your doctor.

Treatment of Leukemia in WWE Wrestlers

While WWE wrestlers are known for their athleticism and strength, they are also at risk for developing leukemia. In fact, several WWE wrestlers have been diagnosed with the disease. While there is no cure for leukemia, treatment options are available. In this article, we will discuss the treatment of leukemia in WWE wrestlers.


Chemotherapy is the main treatment for leukemia. This involves using drugs to kill the cancer cells. The drugs are usually given intravenously (into a vein). Chemotherapy can be given as a single drug or a combination of drugs. You usually have chemotherapy as an outpatient, which means you can go home after each treatment session.


Radiation therapy uses high-energy particles or waves, such as X-rays, gamma rays, electron beams, or protons, to destroy or damage cancer cells. Radiation therapy can be administered externally by a machine that directs the radiation to the cancer cells, or internally by placing radioactive material in implants next to cancer cells.

WWE wrestlers who have received radiation therapy for leukemia include Rey Mysterio Jr., Eddie Guerrero, and Bruce Hart.


There are several types of leukemia, each with its own treatment options. The most common type of leukemia is acute lymphoblastic leukemia (ALL). The main treatment for ALL is chemotherapy, which may be given intravenously (into a vein) or orally (by mouth). Chemotherapy for leukemia may be given in a hospital or outpatient setting.
