"Bröstsjuka" is listed as the cause of death for two men in my Swedish pedigree in the late 1700s - early 1800s. "Breast disease" is the English translation that comes up when I enter the word in translation software.
Can someone help with a better English translation? I am thinking perhaps pneumonia (lung infection) or heart disease of some type. Is this a modern medical term or an old one that you would only find in historical documents?
