Cancer Of The Thyroid

The main symptom of thyroid cancer is a lump in the front of the neck.

But thyroid cancer tends to develop slowly and there may not be any symptoms at first.

Neck lump

Thyroid cancer often causes a painless lump or swelling low down in the front ofthe neck.

However, neck lumps are common and are usually causedby a less serious condition, such as an enlarged thyroid (goitre) . Only around 1 in every 20 is cancer.

A neck lump is more likely to be cancer if it:

• feels firm
• doesn't move around easily under the skin
• gets bigger over time

See your GP ifyou have a swelling or lumpat the front of your neck. While it's unlikely to be cancer, it's important to get it checked out.

Other symptoms

Othersymptoms of thyroid cancer include:

• swollen glands in the neck
• unexplained hoarseness that doesn't get better after a few weeks
• a sore throat that doesn't get better
• pain in your neck
• difficulty swallowing
• breathing difficulties

Rarely, thyroid cancer can affect the production of thyroid hormones and cause diarrhoea and flushing .

These problems can have causes other than cancer, but it's a good idea to see your GP if you develop any persistent symptoms that you're worried about.
