Adults who beat Hodgkin lymphoma and made it past the five-year mark still died at nearly twice the rate expected for the general US population, according to a new analysis of more than 20,000 survivors. The excess risk did not fade at ten years, and the largest cumulative burden came from noncancer conditions and heart disease, not the original cancer.
The findings were published on August 18, 2026, in JAMA Network Open by researchers at The University of Texas MD Anderson Cancer Center, who analyzed SEER cancer-registry data covering diagnoses from 2000 through 2017.
Hodgkin lymphoma is a cancer of the lymphatic system that most often strikes young adults. The National Cancer Institute's SEER program estimates about 8,920 new cases and 1,100 deaths in the United States in 2026, with a five-year relative survival rate of 89.3 percent. Roughly 240,775 Americans were living with the disease as of 2023.
What the numbers show
The MD Anderson team followed 20,057 adult survivors with a median age at diagnosis of 36. Over the study period, they counted 2,899 deaths among the group compared with about 1,481 that would have been expected in a similar slice of the general population. That works out to a standardized mortality ratio of 1.96.

Survivors who reached the ten-year mark were not off the hook. The elevated risk persisted, and the highest relative risks appeared in adults diagnosed between ages 20 and 39, and among several racial and ethnic minority groups.
Why heart disease and other cancers matter most
Recurrence of Hodgkin lymphoma itself remains dangerous relative to a person's baseline risk, but in absolute terms it is not the largest source of extra deaths. The MD Anderson analysis found that noncancer conditions produced the greatest cumulative mortality burden in long-term survivors, followed by secondary cancers, cardiovascular disease and Hodgkin lymphoma recurrence.
That pattern lines up with what hematologists have long observed. A British Journal of Cancer study of long-term Hodgkin survivors reported that subsequent malignancies and cardiovascular disease are the two leading causes of death in this population, with a 68 percent cumulative incidence of developing one or the other by 40 years after treatment.
Radiation and older chemotherapy regimens are thought to damage the heart, blood vessels and other tissues over decades. The MD Anderson team noted that radiotherapy appeared to help survival only in early-stage disease, with no mortality benefit at advanced stages.

What survivors and doctors should do next
Luis Malpica Castillo, M.D., associate professor of Lymphoma and Myeloma at MD Anderson and a senior author on the paper, framed the finding as a call for structured follow-up rather than alarm.
"Thanks to advances in treatment, patients are living longer. However, our findings confirm comprehensive survivorship care focused on cardiovascular health, secondary cancers and other chronic conditions are important to improve long-term survival outcomes," Malpica Castillo said in the MD Anderson announcement.
In practice, that means survivors are typically offered ongoing screening for heart disease and second cancers, along with monitoring for treatment-related effects on the lungs, thyroid and bones. Anyone who has been treated for Hodgkin lymphoma and is unsure what their follow-up plan should look like is best served by raising it with their oncologist or primary care doctor rather than assuming a clean five-year scan closes the file.
There is also a hopeful signal in the data. Mortality rates were lower for patients diagnosed in the more recent years covered by the study, consistent with steady improvements in treatment intensity and radiation targeting.
