Does DCIS have hormone receptors?
Most cases of DCIS are hormone receptor-positive. Hormone receptor-positive DCIS may benefit from hormone therapy (tamoxifen or an aromatase inhibitor) [6,10,15-19]. Learn about hormone receptor status and invasive breast cancer.
Is hormone therapy necessary for DCIS?
Hormonal therapy is recommended for some women with DCIS to help prevent breast cancer from developing and to prevent DCIS from returning after it has been surgically removed. It is only effective for women whose DCIS is “estrogen receptor positive”, which DCIS usually is.
Is DCIS hormone sensitive?
8: All DCIS is hormone sensitive. Not all DCIS is hormone sensitive. Some DCIS is estrogen and progesterone receptor negative (not sensitive to estrogen or progesterone).
Is DCIS tested for HER2?
DCIS is not tested for HER2 for two reasons: one, DCIS is more likely than invasive cancer to be HER2+ (we don’t know why); two, DCIS is not treated with HER2-targeted therapies, so testing DCIS for HER2 would not influence treatment choices.
Does DCIS ever go away?
Clusters of abnormal cells like D.C.I.S. can sometimes disappear, stop growing or simply remain in place and never cause a problem. The suspicion is that the abnormal cells may be harmless and may not require treatment.
Can DCIS be left untreated?
If DCIS is left untreated, it can go on to become an invasive cancer, so it is often called a pre-cancer.
Why did I get DCIS?
DCIS forms when genetic mutations occur in the DNA of breast duct cells. The genetic mutations cause the cells to appear abnormal, but the cells don’t yet have the ability to break out of the breast duct. Researchers don’t know exactly what triggers the abnormal cell growth that leads to DCIS.
What kind of receptors do DCIS cells have?
DCIS cells may have receptors (proteins) on them that allow hormones, such as oestrogen, to attach to the cancer cell. These hormones can help the cancer cells grow. A pathologist tests the tissue that was removed during the biopsy or surgery for oestrogen receptors.
How is the hormone status of DCIS determined?
A pathologist determines the hormone receptor status of the DCIS by testing the tissue removed during a biopsy. Hormone receptor-positive (estrogen receptor-positive/progesterone receptor-positive) DCIS tumors express hormone receptors. This means they have a lot of hormone receptors..
What kind of hormone therapy can you take for DCIS?
Hormone receptor-positive DCIS may benefit from hormone therapy (tamoxifen or an aromatase inhibitor) [ 6,10,15-19 ]. Learn about hormone receptor status and invasive breast cancer. Hormone therapy isn’t recommended for women who have a mastectomy for DCIS.
What does DCIS stand for in medical terms?
Hormone receptor-positive (estrogen receptor-positive/progesterone receptor-positive) DCIS tumors express hormone receptors. This means they have a lot of hormone receptors.. Hormone receptor-negative (estrogen receptor-negative/progesterone receptor-negative) DCIS tumors do not express hormone receptors.
