Are all thymomas cancerous? A ct scan has shown a 3.5 cm by 2.5 cm thymoma pressing on my trachea. Is this cancer? I don’t see the specialist until next week and I’m worried. My chest is sore I have a large lump in my neck. The ct scan was originally to look at my thyroid and I feel generally unwell 

thank you

Hello Mimismum,

Thanks for getting in touch. It’s understandable to have questions about your CT scan, especially when you don’t see the specialist until next week. For many people, waiting on test results can be a very difficult and worrying time.

As nurses on this type of platform, we are unable to diagnose cancer. And although scans can give detailed information, only a biopsy can make a definite diagnosis. Because a thymoma can be benign (non-cancerous) or cancerous, your specialist may recommend further diagnostic tests.

I’m not sure from your post whether the symptoms you describe are new, or whether your hospital team are aware of them. If they are new, or worsening, we’d recommend getting in touch with your hospital team or GP.

While you’re waiting to see the specialist, it may help to talk to family or friends about how you are feeling. And support is available online, if you’re finding it hard to cope. If you’d like to speak to one of the nurses on the Support Line, please give us a call.  

Best wishes

Carole – Macmillan Information Nurse Specialist
