Hello- I am new to this site and am happy to see that there is so much support offered by those positing.
My sister was diagnosed with Stage IV breast cancer in January 2012, after 8 years of being "cancer free". Her mets were primarily to her liver, with other areas affected. She responded unusually well to her chemo regime (though she was told she would be on "lifetime" chemo).
In October, she began experiencing headaches, dizziness, and falling, and it was found that the cancer had spread to her brain and spinal fluids.
She had an Ommaya Reservoir inserted and has been receiving chemo through this port. (Unfortunately, she had leakage through the reservoir and had to have a 2nd surgery to replace it.)
She seems to be deteriorating as far as her mental cognition and her motor skills, and had an MRI and Pet scan this past week. The results of her MRI show a decrease in the cancer in her brain fluid.
My questions are:
If the MRI shows improvement, why does she seem worse? Are the symptoms she is experiencing being caused by the treatment or by the cancer itself? (I'm sure stress is not helping either!!)
Her oncologist said that there is only one chemo that can be used for her brain/spinal fluid cancer. Yet, I seem to see several drugs mentioned online-?
