Is any of this happening?
Be seen today
Seek urgent medical care for repeated episodes of sweating, shaking, confusion, or faintness, especially if low blood sugar has been linked to your tumor.
3
Does any of this apply?
Book an appointment
Arrange a routine medical appointment if you notice a new lump, an unexplained lump that is growing, or ongoing pressure or pain.
These symptoms have many possible causes and do not mean that you have an SFT.
If you have been treated for SFT, contact your treating team before your next planned appointment if you develop a new lump, worsening pain, persistent cough, increasing breathlessness, unexplained weight loss, or new nerve-related symptoms.
Every sign above is quoted from the sofidex article on Solitary fibrous tumor. If you are not sure, err upward — it is always reasonable to be checked.
