[|Human|] I absorbed the mercury from a broken thermometer through my finger about 30 years ago. Could this have caused the Spinal Meningioma that I have had removed from C1. I f not, what causes them? Are they inherited as my mother died froma Malignant brain tumour, as has a 1st cousin and a niece has a tumour on her Pituritry gland?
[|AI|]  Thanks for your question on Chat Doctor. Mercury is known carcinogen, but Single time exposure of any carcinogen can not produce malignancy. Repeated, chronic exposure can cause malignancy. So I don't think that single time mercury exposure before 30 years can lead to cancer. And yes, meningioma can have genetic cause and transmit by hereditary and seen in family. So possibility of hereditary cause is there for your spinal meningioma.
