[|Human|] Chemo for 6 yrs. and radiation ( not sure how long on the radiation). Numerous test in past 6yrs. Family member is now having what I believe are symptoms that are related to the CNS: Lack thought process, falling; these sytoms are severe. She was initially dx. with colon cancer in 2008. Your input is appreciated. Thank You. Initially, she had a section of the colon removed.
[|AI|]  Hi, Thanks for writing in. It is possible that the patient might have developed CNS manifestations due to the cancer itself or as consequence of chemotherapy or radiation therapy. Colon cancer is a challenging condition and more than half of patients might develop metastasis to liver and other organs even after treatment. Please get a brain scan done and rule out any process in the brain that might be causing her symptoms. Her blood count is also important to know if the chemotherapy has caused her anemia and that is why she is fainting and having stroke like symptoms. Please do not worry.
