Explore

• DCIS accounts for about 20% of breast cancers.
• The condition does not usually cause symptoms but can show up on a mammogram, typically as microcalcification clusters.
• DCIS can be treated with surgery, sometimes with radiation and medicine. Chemotherapy is not needed.
• With timely diagnosis and treatment, patients can expect a good outcome.

What is DCIS, and how is it treated?

If you're diagnosed with DCIS, one of the first decisions you'll have to make is whether to treat the condition with lumpectomy or mastectomy. Lumpectomy. Lumpectomy is surgery to remove the area of DCIS and a margin of healthy tissue that surrounds it. This is also known as a surgical biopsy or wide local incision.

What should you do if you're diagnosed with DCIS?

• Lumpectomy: For small, localized areas of DCIS to prevent recurrence in the same breast.
• Total mastectomy: In patients with large areas of DCIS or invasive DCIS to stop the spread of cancer to other parts of the body.
• Radiation or hormonal therapy after surgery: Radiation therapy decreases the risk of recurrence by 50 percent. ...

How should DCIS be treated?

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).

Do I need surgery for DCIS?

How do you stop DCIS recurrence?

Radiation Greatly Reduces Risk of Recurrence for Women with DCIS, a Type of Noninvasive Breast Cancer. Ductal carcinoma in situ (DCIS) is a low-risk form of early-stage breast cancer. Women with DCIS can have radiation after the tumor is removed to lower the risk that the cancer could come back.

What happens if DCIS returns?

Having a history of breast cancer – even stage 0 ductal carcinoma in situ – is considered to be a risk factor for developing breast cancer in the future. In approximately 50 percent of cases, breast cancer that comes back after DCIS treatment is found to be invasive.

How common is DCIS recurrence?

Patients with DCIS have a 15% chance of invasive local recurrence, Dr. Narod noted, but “preventing the invasive local recurrence has nothing to do with preventing death.

Can DCIS come back after lumpectomy and radiation?

A study found that radiation therapy given after DCIS is removed by lumpectomy reduces the risk that the DCIS will come back (recurrence).

Why does DCIS come back?

Positive margins: If the DCIS has positive margins, it means that some cancer cells were left behind at the cancer site and could eventually lead to a recurrence. Being premenopausal: Premenopausal women are younger.

Can a lumpectomy be done twice?

Sometimes after the pathology report is done, the margins are found to contain cancer cells and more surgery is needed. This additional surgery is called a re-excision lumpectomy. Because all the breast tissue is removed during a mastectomy, there's usually no need for more surgery.

Is Tamoxifen necessary after DCIS?

Research shows that radiation therapy and hormonal therapy after surgery for DCIS reduces the risk of being diagnosed with either another DCIS or invasive breast cancer in the future.

How much does radiation therapy reduce risk of recurrence?

Radiotherapy Reduces Risk of Recurrence by More Than 70% in Some Patients With Ductal Carcinoma in Situ.

How much does tamoxifen reduce the risk of recurrence?

Doctors have long known that five years of tamoxifen reduces recurrence by about half during treatment and by nearly a third over the next five years. Aromatase inhibitors, which work only in postmenopausal women, are even more effective than tamoxifen at reducing recurrence and death from breast cancer.

What are the chances of DCIS recurrence after mastectomy?

Clinical outcomes following mastectomy for DCIS are excellent, with both clinical trial and population-based studies consistently reporting a 1%–2% rate of local recurrence with long-term follow-up compared with approximately 10%–15% following breast conservation and radiation (19–22).

What is the recurrence rate of DCIS after lumpectomy?

Results of the National Surgical Adjuvant Breast and Bowel Project B17 trial showed that 13.4% of DCIS patients randomly assigned to receive treatment by lumpectomy alone experienced recurrence as invasive cancer by 8 years after treatment compared with 3.9% of DCIS patients randomly assigned to receive treatment by ...

How often does DCIS spread to lymph nodes?

In conclusion, we found that the incidence of sentinel lymph node metastasis in cases of pure DCIS was 0.39%. This incidence was lower than that in IDC-predominant invasive lesions. Therefore, we believe that sentinel lymph node biopsy in pure DCIS can be safely omitted.

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.

What is a DCIS recurrence?

DCIS recurrence (ductal carcinoma in situ) following surgical removal. DCIS ( or ductal carcinoma in situ) means that malignant cancer cells have been found in the area of the duct wall, but still at an early stage and with no infiltration. One treatment option for DCIS may be to surgically remove the entire mass ( lumpectomy ).

What is the recurrence rate of DCIS?

If surgery must be performed again due to a positive margin, the rate of recurrence for DCIS is thought to be around 42% ( 58% for invasive breast cancer ). So, while the odds for malignant carcinoma recurring in positive margins is around 50%, the overall rate for recurring malignant carcinoma on any lumpectomy is between 3% and 4% for DCIS ...

Is radiation good for women with tumor margins?

Many oncologists still feel that postoperative radiation therapy is beneficial for women with positive and close tumor margins.

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.

How is DCIS diagnosed?

If a doctor sees the calcifications on your mammogram, he or she will recommend more tests, which could include a breast biopsy. During the biopsy, a doctor or other health care provider takes samples of cells or tissues from your body. The cells are examined by a pathologist — a doctor who checks for signs of disease in body tissues.

What is the treatment for DCIS?

Lumpectomy with radiation. The standard treatment is breast-preserving surgery (a lumpectomy) with radiation therapy, which results in successful outcomes for most patients. Cancers can be larger than expected, so about 20% of the time, patients need a re-excision lumpectomy — another surgery — to remove all of the cancer.

What should I expect after a DCIS diagnosis?

The outlook after DCIS diagnosis, Sun says, is encouraging. “With continued, rigorous monitoring, the prognosis for DCIS is excellent,” she explains. “Your doctor will recommend a regular screening schedule to guard against recurrence in the original breast, and to monitor the other breast for any signs of malignancy.

What is the first treatment for DCIS?

Surgery is nearly always the first treatment for DCIS, and it is very effective. There are two types of surgery used for DCIS. The less-invasive option is a lumpectomy, in which a surgeon removes the area that’s abnormal as well as a little bit of the normal tissue around it. This is called a margin.

How to detect DCIS?

Most DCIS is detected from a mammogram that shows abnormal calcifications (small deposits of calcium) in the breast. The doctor may need to conduct additional imaging tests, such as ultrasound or MRI. These are used to determine the full extent of the disease.

What is DCIS in breast?

Ductal carcinoma in situ (DCIS) is a common type of breast cancer , but many patients are confused about their treatment options for the disease. MSK surgeon Melissa Pilewskie explains that surgery is nearly always the recommended treatment, sometimes followed by radiation and possibly hormone therapy as well.

What is a high grade DCIS?

High-grade DCIS cells are the most abnormal and grow the fastest. Hormone-receptor status refers to whether the cancer cells have receptors for estrogen, progesterone, or both.

What is the hardest decision to make after lumpectomy?

Probably the hardest decision faced by women with DCIS is whether to have one of these additional treatments after a lumpectomy. A lot of factors must be considered, including the size and grade of the DCIS, how close the DCIS cells were to the final margin, and the age of the person at diagnosis.

Can a DCIS be lumped?

Most women with DCIS undergo a lumpectomy, possibly followed by additional treatments. In some cases, a mastectomy is recommended, especially if the DCIS covers a large area or appears in multiple spots throughout the breast. With either of these surgeries, the survival rate is excellent.

Can a DCIS come back after a mastectomy?

After a lumpectomy, there is still a risk that the D CIS may come back or become invasive cancer.

What is DCIS in medical terms?

Having a large amount of cancer (10 millimeters or greater) removed during the first round of treatment. Not receiving radiation therapy after surgery. Having a high-or intermediate-grade cancer. Having been diagnosed with DCIS during a physical exam rather than a routine screening.

How long does it take for ductal carcinoma to recur?

Patients who experience a ductal carcinoma in situ recurrence typically do so within 10 years of receiving their original diagnosis. Characteristics that have been associated with an increased risk of recurrence include: Having a large amount of cancer (10 millimeters or greater) removed during the first round of treatment.

Why is ductal carcinoma in situ?

The reason is that ductal carcinoma in situ – by definition – is limited to a small and specific area of the body, which frequently makes it possible for a surgeon to remove all of the cancerous cells from a patient’s body.

Is breast cancer invasive after DCIS?

In approximately 50 percent of cases, breast cancer that comes back after DCIS treatment is found to be invasive. As a result, routine mammograms and physical exams are crucial for detecting any abnormalities as early in their development as possible.

Is DCIS recurrence low?

Even though the DCIS recurrence rate is generally low, survivors should still participate in regular screenings. Having a history of breast cancer – even stage 0 ductal carcinoma in situ – is considered to be a risk factor for developing breast cancer in the future.

What is the advantage of radiation for DCIS?

Instead, the main advantage of radiation for DCIS is to prevent recurrence of DCIS in the breast where the DCIS was removed. A study of more than 1,700 women with DCIS who underwent a lumpectomy evaluated different treatment options.4 The women were randomly assigned either to radiation, tamoxifen, radiation plus tamoxifen, ...

Is mastectomy a good idea for DCIS?

However, mastectomy is a much more radical surgery and is very rarely a good idea for DCIS patients. That’s because almost all women with DCIS live long lives, and undergoing radiation does not affect whether DCIS patients live a long life or not.

Can DCIS spread to other breasts?

In DCIS, some of the cells lining the ducts (the parts of the breast that secrete milk) have developed abnormally, but the abnormality has not spread to other breast cells. DCIS is not painful or dangerous, but it sometimes develops into breast cancer in the future if it is not treated. If it develops into breast cancer, it can spread.

Does radiation help with cancer?

Undergoing radiation had a very small benefit for women in general, and has little impact on your chances of living a cancer-free life. In women treated with radiation, about 10% developed DCIS or breast cancer within the next 10 years after surgery, and it made no difference whether these women took tamoxifen or not.

Can aromatase inhibitors be used instead of tamoxifen?

For postmenopaus al women, aromatase inhibitors may be used instead of tamoxifen. Aromatase inhibitors block the body’s ability to make estrogen. A study of more than 3,000 post-menopausal women with DCIS evaluated the benefits of hormone treatment for women who had lumpectomy and radiation treatment.

Can a DCIS woman develop cancer?

Unfortunately, it is impossible to predict which women with DCIS will develop cancer and which ones won’t. That’s why treatment is recommended.

Is DCIS invasive or invasive?

Since DCIS is not an invasive cancer, it is even less of a threat than Stage 1 or Stage 2 breast cancer, which are the earliest types of invasive cancer.1 For more information, see our free DCIS booklet, and our other articles on DCIS. Most women with DCIS will never develop invasive cancer whether they are treated or not.
