What Mario Lemieux's Story Can Teach Us About Hodgkin Lymphoma
The hockey legend was diagnosed with Hodgkin lymphoma in 1993 and returned to the ice after treatment. Here is what that diagnosis really means, explained simply.
A plain-language summary based on public reporting and trusted sources, linked below.
Please note: this page is educational only — it is not medical advice, and it does not speculate about anyone’s health beyond reliable public reporting. For questions about your own health, talk with your healthcare team.
Seven weeks, a press conference, and a game in Philadelphia
On January 12, 1993, Mario Lemieux told reporters he had Hodgkin lymphoma. He was 27 and leading the National Hockey League in scoring. His foundation's own account says the cancer was found after an enlarged lymph node was taken out of his neck.
He had radiation therapy. NHL.com reports that he returned to the ice on March 2, 1993, roughly seven weeks after the announcement, and played against the Philadelphia Flyers. His foundation says he flew to that game on the day of his final radiation session. He scored a goal and added an assist. He founded the Mario Lemieux Foundation the same year.
Those are the facts he and his foundation made public. Nothing here says what treatment should look like for anyone else. What follows is the medicine.
The cell that defines the disease
Lymphoma is cancer that starts in the lymph system, which is part of the immune defense network. Doctors sort lymphoma into two families, and Hodgkin lymphoma is the smaller one.
For 2026 the American Cancer Society projects about 8,920 new cases of Hodgkin lymphoma and 1,100 deaths in the United States. That is under 1 percent of all new cancers.
What separates it from non-Hodgkin lymphoma is a specific abnormal cell seen under the microscope. Classic Hodgkin lymphoma contains Reed-Sternberg cells, which NCI describes as large, abnormal lymphocytes, a type of white blood cell. NCI divides classic Hodgkin lymphoma into four subtypes: nodular sclerosis, mixed cellularity, lymphocyte depleted, and lymphocyte rich. A separate and less common form is called nodular lymphocyte predominant Hodgkin lymphoma. It carries different markers on its cells, and it is treated as its own entity.
How it usually shows up
The classic opening is a painless swollen lymph node. NCI notes that Hodgkin lymphoma most often shows up in lymph node groups above the diaphragm, the muscle under the lungs, or in the nodes in the middle of the chest. Lemieux's node was in his neck.
Three other symptoms carry a formal name. NCI calls them B symptoms, and it defines them precisely: "Unexplained weight loss (more than 10% of body weight in the 6 months before diagnosis). Unexplained fever with temperatures above 38°C. Drenching and recurrent night sweats."
That fever threshold is 100.4°F. NCI adds that fever and weight loss carry the most prognostic weight, while night sweats alone do not worsen the outlook. NCI also lists itchy skin, especially after bathing or drinking alcohol, and feeling very tired.
When to get checked
NCI says to check with your doctor if you have any of these symptoms and they do not go away:
- Painless, swollen lymph nodes in the neck, underarm, or groin
- Fever for no known reason
- Drenching night sweats
- Weight loss for no known reason in the past 6 months
- Itchy skin, especially after bathing or drinking alcohol
- Feeling very tired
These signs can have other causes, and most swollen nodes are not cancer. Call your care team about any that do not go away. If you have trouble breathing or other severe or sudden symptoms, call 911 or go to an emergency room.
Why the biopsy has to be the right kind
NCI's guidance for clinicians is blunt about this step: "Biopsy (preferably excisional), with interpretation by a qualified pathologist." Excisional means the whole node comes out. A pathologist then looks at the tissue under a microscope for Reed-Sternberg cells.
Staging asks where, not how bad
Staging maps how far the disease has spread. NCI states that "PET scans combined with CT scans have become the standard imaging for clinical staging." A PET scan uses a radioactive sugar tracer that lights up active lymphoma. CT of the neck, chest, abdomen, and pelvis is the alternative.
NCI calls stage III and stage IV advanced Hodgkin lymphoma. A letter is attached to the number. B means the person has those B symptoms, and A means they do not.
Treatment, and the scan in the middle of it
Treatment combines chemotherapy with radiation therapy, and the mix depends on stage and on other risk features. NCI describes ABVD as a frontline chemotherapy regimen. For some patients, NCI describes radiation aimed at the involved lymph nodes.
NCI's clinician summary also describes a PET-CT scan partway through chemotherapy. For some patients, a positive result leads to extra cycles of ABVD and involved nodal radiation.
The outlook, and the decades after it
NCI states that "up to 90% of all newly diagnosed patients with HL can be cured with combination chemotherapy and/or radiation therapy."
That is one of the strongest figures in adult oncology, and it applies to a large group rather than to any single person.
Survivorship care is a real part of this disease. NCI lists late effects that can follow treatment: second cancers, such as lung and breast cancer, heart disease, infertility, an underactive thyroid, and long-lasting fatigue. At 40 years of follow-up, the risk of a second solid tumor reaches roughly 48 percent. That number comes from people followed for four decades, so it reflects the radiation fields and drug doses used in earlier eras.
NCI says regular follow-up with doctors who know how to find and treat late effects is important for the long-term health of people treated for Hodgkin lymphoma.

Put the story in context
Prevention, possible warning signs, screening, and diagnosis
This story relates to Hodgkin lymphoma. The information below is general: it does not reveal anything else about a public person’s health, and not every point applies to every cancer. Personal advice depends on age, symptoms, family history, exposures, and medical history.
Prevention and risk reduction
Not every cancer can be prevented. Avoiding tobacco, protecting skin from ultraviolet radiation, limiting alcohol, staying active, and receiving recommended HPV or hepatitis B vaccination can lower the risk of certain cancers. A risk factor is not a prediction or a cause in one individual.
Symptoms and possible early signs
Possible signs vary and are often caused by conditions other than cancer. Changes worth discussing include a new lump, unexplained bleeding or weight loss, a persistent cough, lasting bowel or bladder changes, a changing skin spot, or symptoms that persist or worsen. Some early cancers cause no symptoms.
Screening and early detection
Screening looks for certain cancers before symptoms begin. Recommended tests exist only for some cancers and depend on age and risk. Screening can have benefits and harms; it is not the same as evaluating a new symptom, and there is no single routine scan or blood test that reliably screens for every cancer.
How cancer is diagnosed
Diagnosis may involve a history and exam, imaging, laboratory tests, and often a biopsy. Pathology can identify the cancer type and may test biomarkers that guide treatment. Symptoms, screening results, tumor markers, or online stories alone cannot confirm cancer.
