Clare Balding health: Presenter's battle with deadly condition – 'cancer is scary'

Causes of thyroid cancer

The NHS explains that thyroid cancer happens when there’s a change to the DNA inside thyroid cells, which causes them to grow uncontrollably and produce a lump.

Although medical professionals are unsure what exactly causes this change, there are a number of factors that can increase your risk.

These include other thyroid conditions – particularly an overactive or underactive thyroid, a family history of thyroid cancer, obesity or having already been exposed to radiation therapy.

Treatments for thyroid cancer

Although there are various treatments for the condition, medical professionals will guide you to which one is best depending on the type of thyroid cancer you have and how far it has spread.
