My dad had ten chemo treatments--last treatment was on December 28, 2011. Doctor wanted him to take a three-month break. Last week my dad began having slurred speech. I took him to the doctor this Monday--Neurologist said he though it was related to the lung cancer. The scheduled an MRI for next Thursday, which is 15 days from the day my dad began having slurred speech. It seems like a very long time to wait. What are your thoughts on this? I would really appreciate hearing from you.
