My husband has been having chemo treatments every 2 weeks for almost a year and is now having a break for the holidays.  Its been  3 weeks since last chemo but he is feeling dizzy and weak with no other flu like symptoms.  Could it be withdrawal symptoms?
Hi, Thanks for writing in. Chemotherapy is treatment of cancer with strong medicines. These medicines fight the cancer cells and destroy them. What happens is after chemotherapy the cancer cells are destroyed and release toxins which circulate in the system. Some of these toxins might cause side effects like weakness and dizziness. The chemotherapy might also affect the normal cells to a small extent and this can cause weakness and also suppression of the immune system. The blood counts are also to be monitored to know if he has anemia or low counts. Please give him a healthy diet every day. If he is having persistent dizziness and headache then a CT scan or MRI scan of the brain is required depending on his cancer and the stage of disease. Please do not worry.
