I'm looking for information on how cancer was diagnosed in the early 1960's. I've tried the search engines for web sites but am having little luck. I can find the history of cancer, but nothing in the way we diagnosed and treated it for a specific time period. I just need very general information for a new screenplay I'm writing. Were X-Rays used? Did MRI's even exist back then? How major of a procedure was a biopsy? Were they even performed? Any where I can be pointed or any info would be great. Thanks!
