Thyroid Cancer

Thyroid cancer arises in thyroid gland cells and can affect tissues in the neck. A thyroid lump is not always cancer, but persistent changes need examination.

What you may notice

Symptoms can overlap with other conditions and vary between people.

  • A neck lump
  • Persistent hoarseness
  • Swallowing difficulty
  • Enlarged neck glands

Understanding care

Clinical care may include thyroid imaging, tissue assessment and specialist treatment discussion. A qualified clinician decides which investigations and options fit the individual situation.

When to seek help

Seek prompt assessment for a persistent unexplained lump, bleeding, weight loss or other new concerning symptoms. Severe bleeding, collapse or major breathing difficulty requires emergency care.

For severe breathing difficulty, collapse, suspected stroke, or another emergency, call local emergency services immediately. In India, call 112.

LITTLE PEOPLE. BIG FEELINGS.

It’s okay to have
a lot of questions.

A doctor visit or an unfamiliar health word can feel scary. You can ask a trusted grown-up to help you understand, one small question at a time.

01

Say how you feel.

“I feel worried” is a good place to start.

02

Ask for simple words.

“Can you explain that in a way I understand?”

03

Bring someone you trust.

A caring adult can help you ask and listen.

For children and their grown-ups. This illustration explains a conversation, not a diagnosis. An adult should seek qualified care for a child who is unwell.
