Katherine Banwell:
Dr. Lee, what are the screening tests for endometrial cancer?
Dr. Nita Karnik Lee:
That’s also a situation that we don’t actually have screening tests for uterine cancer. Again, PAP smears are usually normal in patients who have endometrial cancer because the PAP smear collects just the cells from the outside. Occasionally, sometimes cells that are in the endometrial lining can fall down into the cervix and get found on a PAP smear.
But that’s actually, usually, the exception and not the norm. So, most women I operate on who have endometrial cancer will have had normal PAP smears. But it’s really important to know what symptoms would really trigger the first diagnosis. So, any type of vaginal bleeding after menopause, vaginal spotting, brownish discharge, or anything that seems unusual, really warrants a biopsy. That is not exactly a screening test because screening tests are usually for patients who don’t have any symptoms, but it is really a very important diagnostic test for someone who has any of those symptoms.
Katherine Banwell:
Have there been advances in screening or screening technology that patients should know about?
Dr. Nita Karnik Lee:
Yeah, people are talking about that. We know that there are certain risk factors for uterine cancer, so there has always been a discussion about, what about maybe we don’t screen everyone. Maybe we don’t biopsy everyone, but maybe we should be biopsying some people. So, the issue of patients who have obesity is one of the risk factors, not all of them, because some patients who have obesity don’t have this, and vice versa.
Some patients are very thin and get endometrial cancer, because there are so many different types of endometrial cancer. But I think people have talked about the idea of people who have had a real cycle of irregular periods before menopause, and then may have some risk factors such as obesity, or metabolic syndrome, or diabetes, maybe they should get screened, but that has not been advocated at a public health level. Now, patients who do have a genetic mutation should get screening tests by the endometrial biopsy.
Katherine Banwell:
So, you mentioned some things to look for. How is endometrial cancer diagnosed?
Dr. Nita Karnik Lee:
It’s diagnosed when somebody usually comes in. Most of the people will be diagnosed because they have a symptom such as vaginal bleeding or vaginal discharge. Then they will have either an office-based biopsy, which is called an endometrial pipelle or endometrial biopsy.
Or they can have something that people have heard of before, called a D&C. That stands for dilation and curettage. That means opening up or dilating the cervix just a little bit to allow an instrument to come in and do a small scraping of the lining of the uterus. So, one of those two ways is going to be the way this is diagnosed.
