Brain metastasis - experience with surgery

A "benign meningioma" (if that's what it is)is not related to breast cancer, and is not a form of metastases. It is merely a locally growing tumour growth which has no risk of spreading to other parts of the body, and has arisen locally rather than spread from afar. It's adverse effects are secondary to pressure and oedema (e.g. headhache, nausea and vomiting) and other "local effects" from pressure exerted on nearby tissues. It has a much better outcome than breast cancer metastases as long as it is not pressing on vital structures e.g. those that impair automatic functions. Surgical removal, if possible, can improve enjoyment and quality of life, and is not usually associated with serious consequences if in an easily accessible region of the brain. Talk to your doctors about it. Good luck and be relieved that it's not mets.
