Raisin-like nucleus

Scrapping cells off the cervix (neck of the womb) and analyzing them under the light microscope for changes that may point to the start of cancer of the cervix – Pap smear/test – has greatly reduced deaths from this cancer because treatment can be offered before the pre-cancerous changes worsen.
An abnormality that may be seen under the microscope is a cell nucleus that looks like a raisin (dried grape) – raisinoid nucleus.
The Pap smear - a screening method - is named after its inventor, the Greek doctor Georgios Papanikolaou (1883 – 1962). Most cases or cervical cancer are caused by sexually transmitted human papilloma viruses.
