Thyroid problems after radiation for breast cancer
Part of Cancer, Hormones & metabolism clinical trials.
This study looks at how radiation therapy for breast cancer might affect the thyroid gland, which helps control your body's energy. By tracking thyroid function before and after treatment, doctors hope to learn how to better monitor and support patients.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are older than 18 years.
- You have been diagnosed with breast cancer that has been confirmed by a biopsy.
- Your breast cancer is stage II or stage III.
- Your cancer has not spread to other parts of the body.
- You have features that suggest a higher chance of the cancer coming back in the same area, such as cancer in the lymph nodes, a higher grade, or invasion of blood or lymph vessels.
- You do not have any known thyroid problems before starting radiation, and you have not had thyroid surgery or radiation to the head or neck area in the past.

This trial is testing whether giving radiation therapy after thyroid surgery can help destroy any leftover cancer cells in people with high-risk differentiated thyroid cancer. It is for those who had surgery but some cancer was still left behind.
This study looks at whether adding radiation therapy after surgery can help people with thyroid cancer that is at high risk of coming back. It includes different types of thyroid cancer, like differentiated and medullary types.
This study checks whether chemotherapy for breast cancer affects thyroid function. It follows patients during treatment to see if thyroid problems develop.
This study looks at whether the body's immune response to the thyroid is linked to breast cancer. It may help doctors understand how breast cancer behaves and how to treat it better.
This study tests whether using treatment to keep thyroid-stimulating signals low during radiation to the thyroid area can help prevent a treatment-related drop in thyroid function in children. It is aimed at kids with certain cancers whose radiation plan includes thyroid tissue.
This trial tests how much radiation a specialized whole-body PET/CT scan delivers in patients with differentiated thyroid cancer. It may help doctors better plan treatment for cancer that persists, returns, or has spread—especially when radioactive iodine (RAI) may or may not work.
