Selenium

BCCT plans to write a summary on selenium. While our summary is in development, you can visit these sites:

Clinical Practice Guidelines

The Society for Integrative Oncology’s 2009 clinical practice guidelines found insufficient evidence to recommend selenium for improving side effects of chemotherapy, radiotherapy or surgery, quality of life or lymphedema.1

Access

The Moss Reports list the availability, names  and costs of some selenium supplements. Moss Reports (purchase required).

Cautions

Both About Herbs and CAM-Cancer list adverse reactions, herb-drug interactions and contraindications for selenium.  Read the summaries for more information. About Herbs: Selenium and CAM-Cancer: Selenium—during cancer treatment.

Selenium toxicity, more so from supplements than from dietary sources,  can be serious, so careful attention is needed about doses and the length of time you take selenium. Doses are in micrograms (μg), not milligrams (mg). A microgram is 1/1000 of a milligram. 

According to CAM-Cancer, selenium supplementation may increase the risk of nonmelanoma skin cancer recurrence, especially in fair-skinned people.

Dosing

BCCT does not recommend therapies or doses, but only provides information for patients and providers to consider as part of a complete treatment plan. Patients should discuss therapies with their physicians, as contraindications, interactions and side effects must be evaluated.

Dosage recommendations are available from these sources:
