Some back story first. My dad has advanced stage 4 lung cancer that spread to his liver and bowel and is terminal. He has been in various treatments for the last two years. He is currently on a new chemo cycle. About two months ago he started feeling pain in his abdomen and started taking oxycodone and recently as of two weeks ago also started fentynal 50mg patch. He also started chemo again a week ago as he had progression on his second immunotherapy. For the last 5 months he has become more angry and agressive towards myself and other family members caring for him and we just put it down to having terminal cancer, pain & medications etc. However over the last month he has become physically violent towards my mother and has given her two busted lips and yesterday pushed her into a window which bruised one whole side of her face. Can cancer or medications cause someone to do this? Has anyone else experienced the same thing?. He has never been violent before now.
