What does estrogen receptor positive mean?

Estrogen receptor is an examination item. If estrogen receptors are found during breast examination, it is a type of breast cancer, which refers to the growth signals of cancer cells received from estrogen. This is also a relatively common type of breast cancer. The harm to patients is very great. Regular treatment must be carried out in time, and conditioning work should be done in daily life to avoid causing greater harm.

Estrogen-positive breast cancer is a type of breast cancer in which the cancer cells receive growth signals from the hormone estrogen. Estrogen receptor-positive breast cancer is the most common type of breast cancer.

In contrast, progesterone-positive (PR-positive) breast cancer cells receive growth signals from progesterone. If the cancer cells have a mix of both types of receptors, doctors call it hormone receptor-positive breast cancer. Two out of every three breast cancers are hormone receptor-positive breast cancers, but estrogen-positive breast cancer is one of the most common types of breast cancer.

Symptoms of estrogen receptor-positive breast cancer are similar to those of other types of breast cancer. The most common symptom of breast cancer, including estrogen receptor-positive breast cancer, is a mass. Other symptoms include: skin redness, nipple discharge, breast swelling, breast or nipple pain, thickening or redness of the nipple or breast skin, changes in breast shape, breast cancer testing and diagnosis,

Your doctor needs to determine what type of breast cancer you have. To do this, they may do a biopsy to remove a small amount of cancerous tissue for examination. Immunohistochemical staining or IHC testing is a specialized method used to detect estrogen and progesterone receptors, which will help doctors determine the type of breast cancer and guide treatment for breast cancer.

How a doctor treats estrogen-positive breast cancer depends on many factors, including the stage, how far it has spread, and where the tumor came from. If the cancer is estrogen or progesterone receptor positive, hormone therapy will almost certainly be part of the treatment plan. There are several different types of hormone therapy medication regimens.
