A 36 year old man is suffering from brain tumour #braintumor is an abnormal growth of tissue in the brain. Unlike other tumors, brain tumors spread by local extension and rarely metastasize (spread) outside the brain. A benign brain tumor is composed of non-cancerous cells and does not metastasize beyond the part of the brain where it originates. A brain tumor is considered malignant if it contains cancer cells, or if it is composed of harmless cells located in an area where it suppresses one or more vital functions..
Is that really the definition? If a tumor is without infiltration elements and lack cancerous cells it shouldn't be considered malignant regardless of compression to vital parts? I mean this is part of what benign tumours do...?
Taken from several reputable sources: "A benign brain tumor grows slowly, has distinct boundaries, and rarely spreads. Although its cells are not malignant, benign tumors can be life threatening if located in a vital area." - so to clarify, a defined benign tumour can never be classified as malignant regardless of pathological action.
