Hi,

i am writing because me and my friend both work in a medical lab for the summer. And two weeks ago, we were dealing with ethidium bromide, and long story short, my idotic friend ingested ethidium bromide along with food. I got really worried and told him to get a check up but he keeps saying that there are no harmful effects on human because they didn't prove it so. I wish I could force my friend to a doctor, but he keeps telling me that it's not that bad(not as bad as people talk about it). Last I checked, ethidium bromide is very mutagenic right? It can cause oesophagal and stomach cancer no? If it's taken in through ingestion, can it not get into the lymphatic system and as such cause some real bad problems? I just want to know to be sure that he's not doing anything stupid by not going to a doctor.
