Second Cancers After Hodgkin Lymphoma

Cancer survivors can be affected by a number of health problems, but often a major concern is facing cancer again. If a cancer comes back after treatment it is called a recurrence. But some cancer survivors may develop another type of cancer later. This is called a second cancer.

People who have had Hodgkin lymphoma can get any type of second cancer, but research has found they have an increased risk of certain cancers, including:

The increased risk of many of these cancers seems to be linked to treatment with radiation. For example:

  • Women who have had chest radiation (especially before age 30) have been found to have a higher risk of breast cancer.
  • Radiation to the neck has been linked to a higher risk of thyroid cancer.
  • Radiation to the chest has been linked to a higher risk of lung cancer.

But over time, the use of radiation to treat Hodgkin lymphoma has changed. Radiation is now given in lower doses, and often only to the areas directly affected by Hodgkin lymphoma. The risks with modern radiation treatment are likely to be lower, although long-term studies are needed to be sure

Chemotherapy (chemo), especially with drugs called alkylating agents (such as mechlorethamine) has been linked with a higher risk of several types of cancer, including leukemias. Treatment with alkylating agents has become much less common, so these risks are probably not as high as they were in the past, but long-term follow-up studies are needed to be sure. 

Follow-up care after Hodgkin lymphoma treatment

After completing treatment for Hodgkin lymphoma, you should still see your doctor regularly and may have tests to look for signs that the cancer has come back. Let them know about any new symptoms or problems, because they could be caused by the lymphoma coming back or by a new disease or second cancer.  

Women who were treated with radiation therapy to the chest (such as mantle field radiation therapy) before age 30 have an increased risk of breast cancer. The American Cancer Society recommends yearly breast MRIs in addition to mammograms and clinical breast exams beginning at age 30 for these women.

The Children’s Oncology Group has guidelines for the follow-up of patients treated for cancer as a child, teen, or young adult, including screening for second cancers. These can be found at

Survivors of Hodgkin lymphoma should also follow the American Cancer Society guidelines for the early detection of cancer, such as those for colorectal and lung cancer. Most experts don’t recommend any other testing to look for second cancers unless you have symptoms.

Can I lower my risk of getting a second cancer?

There are steps you can take to lower your risk and stay as healthy as possible. For example, it’s important to stay away from tobacco products. Smoking increases the risk of many cancers, including some of the second cancers seen in people who have had Hodgkin lymphoma.

To help maintain good health, Hodgkin lymphoma survivors should also:

These steps may also lower the risk of other health problems.
