Are you breaking down Estrogen properly?

Thursday, November 17th, 2011

If there is one thing women fear, it is breast cancer. Perhaps it is the fact that breasts are such a feminine attribute, strongly associated with attractiveness and fertility, that women associate breast cancer with a loss of sexuality and even a loss of self. Some women are afraid of the various treatment modalities such as surgery, chemotherapy and radiation. These treatments may cause pain, sickness, or physical changes such as hair loss and even breast loss. I have had many patients state they feel that the treatment is worse than the disease.

 

Everyone knows someone who has had it – family, friends, or coworkers. According to BreastCancer.org, 1 out of every 8 women will develop invasive breast cancer in their lifetime. And our risk of getting breast cancer increases as we age.

 

Many women do not go in for regular screening because they do not want to hear bad news. The idea is that “no news is good news.” But nothing could be further from the truth. Breast cancer, like most cancers, is completely treatable if caught early. Regular screening and follow up with your doctor is extremely important, but what can we do to prevent breast cancer?

 

Research shows that the way our bodies break down estrogen can increase our risk of breast cancer. Estrogen is metabolized in the liver and the metabolites, or byproducts of metabolism, are a key to developing breast cancer. There are six metabolites that we look at – four metabolites are considered “bad” and only two are considered “good”. And although all six metabolites may be present, it is the ratios of these metabolites to one another that are important. One of the most reviewed ratios is commonly called the 2:16 ratio. If this ratio is less than 2, meaning that you have too much of the bad estrogen (16) and not enough of the good estrogen (2), studies show that you are at an increased risk of breast cancer, as well as other estrogen driven cancers such as cervical cancer and ovarian cancer.

 

How can you find out how your liver is breaking down estrogen? A simple morning urine sample can be sent to the lab for evaluation to determine your estrogen metabolism ratios. Once we have that information, we can assess your risk and take steps to mitigate that risk. This test can also be used to monitor current treatment plans to reduce breast cancer risk, as well as to monitor hormone replacement therapy. It is a great test to determine a woman’s osteoporosis risk as well.

 

What can affect the balance of this ratio? Diet and exercise have a strong impact on the 2:16 ratio. Adding flax seeds, cruciferous vegetables, and soy products into your diet can increase this ratio. Likewise obesity and alcohol consumption can have a negative impact. Definitely kidney function and fluid consumption can affect this ratio so I recommend a basic CBC and CMP with the estrogen metabolism test. Your doctor will be able to interpret your labs, determine how you metabolize estrogen, and create a plan to shift your metabolism to a different pathway if necessary.

Diagnosing Ovarian Cancer

Sunday, April 10th, 2011

Ovarian cancer is one of the most difficult cancers to diagnose and catch at an early stage.  Early warning signs actually mimic digestive disorders and are easily overlooked or blamed on our dietary habits.  If a woman has abdominal pain or bloating that persists for several weeks, and does not respond to standard natural therapies, then she should remind her doctor to rule out ovarian cancer.  If a woman starts to lose her appetite or starts to feel full quickly when eating, then she should consider asking her doctor about ovarian cancer. Other symptoms include vaginal bleeding, sense of heaviness in the pelvis, swollen abdomen, unexplained back pain that gets worse over time, and unexplained weight loss or weight gain.

In diagnosing ovarian cancer, doctors review the severity and duration of symptoms, and then follow up with physical exams and lab tests.

1)    Manual pelvic exam – This examination is done every time a pap or thin prep test is performed as part of an annual well woman’s exam.  Although the pap/thin prep tests are designed to rule out cervical cancer, the manual exam that follows gives the doctor a lot of information about the health of the organs in the pelvis.  Through palpation of the uterus and ovaries, the doctor may be able to discern the presence of uterine fibroids, ovarian cysts or other unusual growths that may warrant further testing.  If ovarian cancer is suspected based on reported symptoms, this will be the first exam performed by a doctor.

2)    Pelvic ultrasound – Imaging of the pelvis helps confirm the size, shape and location of the pelvic organs as well as the presence of any other growths.  This will typically be the next lab ordered after the manual exam.  Bloodwork may also be ordered.

3)    Tissue sample - The first two steps are not enough to diagnose ovarian cancer.  If the symptoms, manual exam, and ultrasound suggest unusual cell growth, the next step is often biopsy or removal of one ovary for review by a pathologist.  If cancer is found, then follow up with an oncologist to decide the best course of treatment.

Patients often ask about the CA-125 test, especially if they have a strong history of cancer in their family.  This blood test is not included in an annual well woman’s examination because it is not a valid screening test.  CA-125 is a protein found on the surface of healthy ovarian cells.  The definition of cancer is unregulated cell growth, so a blood test indicating high levels of CA-125 in the body should be a clear sign of ovarian cancer, right?  Not so fast.  CA-125 levels in the blood are elevated during pregnancy, as well as in the presence of endometriosis, ovarian cysts, uterine fibroids, and normal menstruation.  In addition, early stage ovarian cancer does not typically elevate CA-125 levels.  Therefore a negative CA-125 test does not rule out ovarian cancer and a positive CA-1235 does not diagnose ovarian cancer.  So what’s the point of that test?  Once a woman has been diagnosed with cancer, and is working with an oncologist, the oncologist may run this test periodically to monitor the efficacy of their treatment protocol.

One screening test that does assess a woman’s risk of developing ovarian cancer is the genetic screening for BRCA 1 and BRCA 2.  These genes are responsible for a small number of cases of ovarian cancer.  Any woman with a family history of breast cancer or ovarian cancer should consider this test.  Due to the generality of the symptoms of ovarian cancer, patients must be their own best advocate.  If you are concerned about your family history and believe you may be at risk, insist on further imaging and testing from your doctor.
