I'm a 55 y/o woman, my PAP came back "rare atypical squamous cells", and my Primary Care MD is sending me for additional tests. Does "rare" in that mean few, or could it mean rare as in not ususal? I did have a CT scan come back, about 5 months ago, with a spot that a MD said was "probably" just the plura pinched together, and I'm presently showing signs of a colon problem (my Father had colon cancer).
