[|AI|]  Hi, Thanks for writing in. Sorry to hear about the death of your husband from kidney cancer and may his soul rest in peace. There is saliva constantly being generated in the mouth in each of us. By reflex action we tend to swallow it and are unaware of doing this activity. When a person dies, there might be a sort of choking in some people and this is when the person salivates and there is a struggle to breathe. There might be violent coughing and the small vessels might rupture. This action causes foaming which is mixed with blood and gives a pink tinge. My explanation is only a possibility based on the facts mentioned.
