I am writing this post for my mother. She has cancer in the lining of her brain and was receiving radiation for it. Now she has been admitted to the hospital with low blood count, shivers, fever only showing on rectal reading, and delirium. They are treating her for pneumonia but the cultures have not come back. Her CA-15 3 went from 586 to 180.
Could all of this be because the radiation is working and the cancer cells are dying. Her radiation oncologist said that it would cause swelling and headaches.
