Are crazy mood swings and screaming a side effect of medicines?
Patient: my father was diagnosed with stage 4 colon cancer in April 2012.  He was completely healthy and had no idea it even was there.  He had his first surgery in May to remove the large tumor, 14 lymph nodes and his appendix.  In July he went back for the spots to be taken off his liver so they took the entire right side of his liver and large pieces of the left side along with his gallbladder.  after the 2nd surgery, his blood pressure medicine was not working right so they switched him to lopressor.  since coming home he has no desire to do anything and has crazy mood swings where he just screams.  we are not sure if this is all coming from the medication or something else.  My mom has even questioned if the cancer spread to his brain because he is not the same person he was before going in for the 2nd surgery.  After the first one he was back riding his bicycle 10 miles on some days.  He was not given a life expectancy but his doctors told us that he will be with us 10 years from now although they would have to go back in and clean up his liver again within that time.  We are trying to figuring out what is causing all these changes in him so any help would be great!  thanks Doctor: Mood swings and personality changes need to be investigated in a cancer patient who already has stage 4 disease with liver metastasis. His brain should be imaged with an MRI scan. If no evidence of metastasis in brain is found then he should be seen by a psychiatrist for evaluation as the stress of chronic illness might be causing it. Please discuss it with your treating oncologist.
