DCIS is considered a pre-cancer because sometimes it can become an invasive cancer. This means that over time, DCIS may spread out of the ducts into nearby tissue, and could metastasize. Currently, there’s no good way to predict which will become invasive cancer and which won’t. Therefore, almost all women with DCIS will be treated.
Is DCIS really cancer?
While DCIS isn’t considered life threatening, it does increase the risk of developing invasive breast cancer later in life. DCIS usually is treated with surgery to remove the cancer -- lumpectomy in most cases. After surgery, hormonal therapy may be recommended if the DCIS is hormone-receptor-positive (most are).

What is high grade DCIS?
What is the treatment for DCIS stage 1?
Surgery is the first step to treat DCIS. It removes the abnormal tissue from the breast. Depending on how far the DCIS has spread within the milk ducts, surgery can be mastectomy or lumpectomy. If DCIS is spread throughout the ducts, affecting a large part of the breast, a total (simple) mastectomy will be done.
What is the treatment for DCIS stage 0?
Surgery is the main treatment for DCIS. Most women are offered breast-conserving surgery. If there are several areas of DCIS in the breast, doctors may do a mastectomy to make sure that all of the cancer is removed.
How long does it take for low grade DCIS to become invasive?
It assumes that all breast carcinomas begin as DCIS and take 9 years to go from a single cell to an invasive lesion for the slowest growing lesions, 6 years for intermediate growing DCIS lesions, and 3 years for fast-growing DCIS lesions.
How many radiation treatments are needed for DCIS?
A typical course of radiation treatment for DCIS involves 16 sessions given over three weeks.
What does low grade DCIS mean?
DCIS that is low grade, is nuclear grade 1, or has a low mitotic rate is less likely to come back after surgery. DCIS that is intermediate grade, is nuclear grade 2, or has an intermediate mitotic rate falls in between these two.
Is hormone therapy necessary for DCIS?
Hormone therapy isn't a treatment for DCIS in and of itself, but it can be considered an additional (adjuvant) therapy given after surgery or radiation in an attempt to decrease your chance of developing a recurrence of DCIS or invasive breast cancer in either breast in the future.
Do I need a mastectomy for DCIS?
Most women with DCIS or breast cancer can choose to have breast-sparing surgery, usually followed by radiation therapy. Most women with DCIS or breast cancer can choose to have a mastectomy. You have small breasts and a large area of DCIS or cancer. You have DCIS or cancer in more than one part of your breast.
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.
Can biopsy cause DCIS to spread?
Won't a Needle Biopsy Cause Cancer Cells to Spread? Patients are often concerned that the needle biopsy will disrupt and disseminate cancer cells, but this is not the case.
What can I expect after my first radiation treatment?
The most common early side effects are fatigue (feeling tired) and skin changes. Other early side effects usually are related to the area being treated, such as hair loss and mouth problems when radiation treatment is given to this area. Late side effects can take months or even years to develop.
Do you lose hair with radiation?
Radiation therapy can also cause hair loss on the part of the body that is being treated. Hair loss is called alopecia. Talk with your health care team to learn if the cancer treatment you will be receiving causes hair loss.
How soon do you start radiation after a lumpectomy?
Radiation after Lumpectomy A course of radiation starts between six and 12 weeks after lumpectomy surgery. Most frequently, we target the entire breast (whole-breast radiation). In some cases, we also treat nearby lymph nodes.
What is the treatment for DCIS?
In most people, treatment options for DCIS include: Breast-conserving surgery (lumpectomy) and radiation therapy. Breast-removing surgery (mastectomy) In some cases, treatment options may include: Lumpectomy only.
What is DCIS on a mammogram?
DCIS is most often discovered during a mammogram used to screen for breast cancer. If your mammogram shows suspicious areas such as bright white specks (microcalcifications) that are in a cluster and have irregular shapes or sizes, your radiologist likely will recommend additional breast imaging. You may have a diagnostic mammogram, which takes ...
What is radiation therapy after lumpectomy?
Radiation therapy after lumpectomy reduces the chance that DCIS will come back (recur) or that it will progress to invasive cancer.
What is a calcification on a mammogram?
Calcifications are small calcium deposits in the breast that show up as white spots on a mammogram. Large, round or well-defined calcifications (shown left) are more likely to be noncancerous (benign). Tight clusters of tiny, irregularly shaped calcifications (shown right) may indicate cancer.
Can alternative medicine cure DCIS?
Alternative medicine. No alternative medicine treatments have been found to cure DCIS or to reduce the risk of being diagnosed with an invasive breast cancer. Instead, complementary and alternative medicine treatments may help you cope with your diagnosis and the side effects of your treatment, such as distress.
Can you have a mastectomy with DCIS?
Most women with DCIS are candidates for lumpectomy. However, mastectomy may be recommended if: You have a large area of DCIS.
How to treat DCIS?
Surgery is the first step to treat DCIS. It removes the abnormal tissue from the breast. Depending on how far the DCIS has spread within the milk ducts, surgery can be mastectomy or lumpectomy. If DCIS is spread throughout the ducts, affecting a large part of the breast, a total (simple) mastectomy will be done.
What is a Lumpectomy for DCIS?
Lumpectomy for DCIS is usually followed by whole breast radiation therapy to lower the risk of [ 6-13 ]: DCIS recurrence (a return of DCIS) in the treated breast. Invasive breast cancer in the treated breast.
Why is DCIS called in situ?
It’s called “in situ” (which means “in place”) because the cells have not left the milk ducts to invade nearby breast tissue. DCIS is also called intraductal (within the milk ducts) carcinoma. You may hear the terms “pre-invasive” or “pre-cancerous” to describe DCIS. DCIS is treated to try to prevent the development of invasive breast cancer.
How do pathologists determine the hormone receptor status of a DCIS tumor?
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..
Can a lumpectomy be done with DCIS?
If there’s little spread of DCIS within the ducts, a choice can be made between mastectomy or lumpectomy. With lumpectomy, the surgeon removes only the abnormal tissue in the breast and a small rim of normal tissue around it. The rest of the breast is left intact.
Can you get DCIS without radiation?
Because DCIS might progress to invasive breast cancer, almost all cases of DCIS are treated. Surgery (with or without radiation therapy) is recommended to treat DCIS. After surgery and radiation therapy, some people take hormone therapy. Learn more about treatments for DCIS. Learn about the risk of invasive breast cancer after treatment for DCIS.
Can DCIS progress to breast cancer?
DCIS is non-invasive, but without treatment, the abnormal cells could progress to invasive cancer over time. Left untreated, it’s estimated 20-50 percent of DCIS cases may progress to invasive breast cancer [ 1-5 ]. Health care providers cannot predict which cases of DCIS will progress to invasive breast cancer ...
What is DCIS in mammography?
Before the advent of routine mammography, DCIS (ductal carcinoma in situ) was rarely detected. But today, DCIS accounts for 20% of breast cancer diagnoses and would be the fifth most common cancer in women if classified independently. Apar Gupta. Often called “stage zero breast cancer,” DCIS growths are confined to the inside ...
How long does it take to survive DCIS?
It’s important to understand that radiation and hormone treatments do not change survival—the 10-year survival rate for women diagnosed with DCIS is 98% regardless of whether they receive either treatment. These treatments instead reduce the risk of breast cancer down the road.
Can hormone therapy be used for DCIS?
However, not all treatments for invasive breast cancer may be optimal for DCIS, Gupta says. His study suggests that in most cases of DCIS, the side effects of hormone therapy may outweigh its benefits. The CUIMC Newsroom spoke with Gupta to learn how the study’s findings can help providers and their patients navigate treatment for DCIS.
Is DCIS a pre-invasive cancer?
“DCIS is considered a pre-invasive cancer, but the current standard of care is to treat it like an early-stage invasive breast cancer,” says Apar Gupta, MD, ...
Can DCIS be overtreated?
Since treatment of DCIS after surgery doesn’t improve survival, there is a growing concern that DCIS may be overtreated if the benefit of these treatments is outweighed by their impact on quality of life.
Can you have a double mastectomy for low grade cancer?
Some surgeons are not keen to do a double mastectomy for low grade cancers, but this is your body, so, if this is what you'd prefer, stick to your guns. I found the best way was to draw up a list of pros and cons for both operations and then a list of questions for my consultant.
Is DCIS invasive?
as I understand it the low grade DCIS can often be left as a ‘wait and see’ approach. Please remember DCIS is totally contained in the milk duct, is non invasive and not life threatening. There is an almost 100% survival rate after 10 years.
What is a low grade DCIS?
DCIS that is low grade, is nuclear grade 1, or has a low mitotic rate is less likely to come back after surgery. DCIS that is intermediate grade, is nuclear grade 2, or has an intermediate mitotic rate falls in between these two. Patients with higher grade DCIS may need additional treatment.
What does it mean when DCIS touches ink?
If DCIS is touching the ink (called positive margins ), it can mean that some DCIS cells were left behind, and more surgery or other treatments may be needed. Sometimes, though, the surgeon has already removed more tissue (at surgery) to help make sure that this isn’t needed.
What is in situ carcinoma?
What is in-situ carcinoma (or carcinoma in situ) of the breast? This term is used for the earliest stage of breast cancer, when it is confined to the layer of cells where it began. The normal breast is made of tiny tubes (ducts) that end in a group of sacs (lobules).
Is LCIS the same as DCIS?
LCIS is discussed on a different page. Sometimes DCIS and LCIS are both found in the same biopsy. In-situ carcinoma with duct and lobular features means that the in-situ carcinoma looks like DCIS in some ways and LCIS in some ways (when looked at under the microscope), and so the pathologist can’t call it one or the other.
Can DCIS be left untreated?
Still, we don’t really understand it well. We don’t think that all DCIS would go on to become invasive cancer, but we can’t tell which DCIS would be safe to leave untreated.
Can DCIS come back after surgery?
Later, when the entire area of DCIS is removed (with surgery), an accurate measurement can be done. The larger the area of DCIS, the more likely it is to come back (recur) after surgery. Doctors use information about the size of the DCIS when recommending further treatments.
Can calcifications be seen on a mammogram?
They can be seen both on mammograms and under the microscope. Because certain calcifications are found in areas containing cancer, their presence on a mammogram may lead to a biopsy of the area. Then, when the biopsy is done, the pathologist looks at the tissue removed to be sure that it contains calcifications.
How to remove DCIS?
DCIS can often be removed via a lumpectomy— a surgery that spares the surrounding breast tissue. (In some cases, if DCIS has infiltrated multiple ducts or a tumor has grown large enough, removing the entire breast via mastectomy may be recommended.)
What is a high grade DCIS?
High-grade DCIS is sometimes described as “comedo” or “comedo necrosis,” which means that dead cells have built up inside the fast-growing tumor. The higher the grade, the greater chance a person has of also having invasive breast cancer, either with the DCIS or at some point in the future. 10 of 22. View All.
What is a DCIS score?
“You get back what’s called a DCIS score, from zero to 100, that tells you the likelihood of a DCIS recurrence or of an invasive cancer in the next 10 years,” says Dr. White.
What is the DX test?
Sometimes doctors will recommend a genomic test, called the Oncotype DX test, to help determine a DCIS patient’s risk of getting another cancer in the future. A sample from the DCIS biopsy or lumpectomy is sent to a lab, where pathologists study the activity of 12 different cancer-related genes.
How does DCIS affect breasts?
DCIS occurs when cells in one of those milk ducts have mutated and multiplied to look like cancer cells. About one in five newly diagnosed breast cancers is DCIS.
What is DCIS in breast cancer?
DCIS occurs when cells in one of those milk ducts have mutated and multiplied to look like cancer cells. About one in five newly diagnosed breast cancers is DCIS. Because those cells usually stay confined to the duct and do not spread to surrounding tissue, DCIS is also known as stage 0 breast cancer or sometimes pre-cancer. ...
How many DCIS cases were diagnosed in the 1990s?
In the 1990s, only about 15,000 to 18,000 DCIS cases were diagnosed per year, she says; now, that number has grown to more than 60,000, according to the American Cancer Society. “That’s because so many women are now getting mammograms, and the technology is so good, that we pick up very small lesions,” says Dr. White.
What is the primary goal when treating DCIS?
Preventing invasive disease, which carries a possibility for metastasis, is the primary goal when treating DCIS. Unfortunately, we are not yet in a position to accurately predict which cases of DCIS will progress and which will not.
What is ductal carcinoma in situ?
Ductal carcinoma in-situ is also referred to as noninvasive, or Stage 0 breast cancer. It is primarily diagnosed by screening mammogram, as it often does not form a palpable lump. DCIS accounts for approximately 20% of all breast cancers detected by mammography.
Is there a survival advantage to undergoing surgery for low grade DCIS?
They concluded that there was no survival advantage to undergoing surgery in cases of low grade DCIS.
Is DCIS a cancer?
A hallmark of cancer is the ability to invade surrounding organs and metastasize, and whether or not DCIS should even be considered “cancer” has been the subject of much debate. Dr. Laura Esserman and others have suggested that DCIS be re-classified as an Indolent Lesion of Epithelial Origin (2).
