question: Hi this question is regarding my aunt who is 68 year old, she has lost central vision and sees gray spots, her white blood cell count is very high. She is anemic and is experiencing dizziness, chest palpitations and a fullness or bloated feeling in her lower abdomen and feels the need to urinate frequently. She has visited several doctors and no one is able to effectively provide her relief or a reason for these symptoms. Is this likely to be a brain tumor?
