Second Brain Tumour Not Treatable (now)

I recently posted that I had secondary breast cancer with a brain tumour removed in October, I saw the Radiologist & he told me I have another one on the other side. Well I saw my Surgeon last week with a friend & have been told there's nothing he can do except monitor it with MRI to check if it grows. If he removed it or if they did radiation on it it's in the area where I would have permanent damage to my right leg. It possibly has been there all along but too small to be detected so I'm booked in for an MRI at the end of the month (they are so booked up). Now I worry whether it's grown & if other little tumours have popped up as he said some people end up with 30 tumours, in that case they have to do full brain radiation which causes brain damage. My friend & I went armed with questions but afterwards couldn't believe neither of us expected to hear 'permanent damage' & didn't ask to what extent that damage would be. He said if I have anything happen to the right leg to go hospital & there's a very minimal chance of seizures. So a long wait for answers to my next results, it's the outcome I wanted & he was upbeat about it, no treatment for now & he was very interested in my trip to London & told me to go book in more concerts as I left. :D <3
