Hormone receptor testing is another type of breast cancer diagnosis that should be known.

Breast cancer is a disease caused by abnormal growth of cells in the breast. In fact, approximately 85-90% of breast cancers are caused by genetic abnormalities. as a result of increasing age while only 5-10 percent of cancers are caused by abnormalities that are inherited in the family. The disease affects not only the mental health of the individual. But it also affects your ability to do everyday things. and sexual performance Breast cancer is diagnosed using a mammogram, ultrasound, and breast biopsy. But today we will take you to get to know the type of examination. hormone receptor testing

What is a hormone receptor test?
Both women and men have the hormones estrogen and progesterone. But both hormones play an important role in the menstrual cycle. and female sexual development Estrogen receptors (ER) and progesterone receptors (PR) are important proteins. may be found in breast cancer cells

These hormone receptors receive information from substances in the bloodstream and affect how hormones work in women, such as enlargement of the breasts. Like other good cells, breast cancer cells have hormone receptors. and respond to those hormonal signals Knowing that breast cancer cells have hormone receptors Whether or not it is important to prescribe a treatment

Test for estrogen and progesterone receptors
Test for estrogen and progesterone receptors It is the basis of breast cancer diagnosis. The most common method used today is oncological examination to look for estrogen and progesterone receptors so-called Using the immunohistochemical technique (Immunohistochemistry: IHC) Estrogen and progesterone receptors can be assessed in cancer cells.

from a sample of breast tissue Cells in the breast may contain only one type of hormone receptor. or two types The results of the examination should be accurate. Because determining the right treatment for the patient is important. They can also avoid side effects from ineffective treatments.

examination results

There are four possible types of test results:

ER (+)
Estrogen receptor positive It means that the receptors of cancer cells respond to estrogen. ER (+) type breast cancer is the most common type. And in some cases, chemotherapy is not needed after surgery.

ER (+) PR (+) 65 percent of cases of estrogen receptor-positive breast cancer. Cells contain progesterone receptors that promote breast cancer growth.
ER (+) PR (-) In about 13 percent of cases of breast cancer, estrogen promotes growth. and the spread of cancer cells not progesterone
ER (-) PR (+)
In about 2 percent of cases of breast cancer, progesterone tends to promote the growth of cancer cells. We recommend that you study further research. To understand progesterone receptor positive breast cancer

ER (-) PR (-)
about half of cases of breast cancer Breast cancer cells do not have both hormone receptors. Also known as hormone receptor negative. Experts suggest that hormone receptor-negative breast cancer will respond better to chemotherapy hormone receptor positive breast cancer
