Thus far, we have been focused on reducing that risk at all costs and treating DCIS like an early-stage breast cancer: The first step is surgery—usually lumpectomy—followed by radiation treatment for three to four weeks and finally hormone therapy for five years.
Full Answer
How is ductal carcinoma in situ (DCIS) treated?
Introduction: Ductal carcinoma in situ (DCIS) is a non-invasive breast cancer. Without treatment, DCIS can progress to invasive breast cancer over time. So, almost all cases of DCIS are treated. Treatment involves surgery, with or without radiation therapy.
What is ductal carcinoma in situ?
Ductal carcinoma in situ (DCIS) means the cells that line the milk ducts of the breast have become cancer , but they have not spread into surrounding breast tissue.
Can you have lumpectomy with radiation therapy for DCIS?
Radiation therapy isn’t given to people who are treated with mastectomy for DCIS. Lumpectomy for DCIS is usually followed by radiation therapy to lower the risk of [1]: Overall survival appears similar for women with DCIS who have lumpectomy with or without radiation therapy [2-3].
What is the prognosis of DCIS with and without radiation therapy?
Overall survival is the same for women with DCIS who have mastectomy and those who have lumpectomy (with or without radiation therapy) [ 6 ]. In the U.S., most women with DCIS are treated with lumpectomy followed by radiation therapy [ 7 ].
How many radiation treatments are needed after lumpectomy?
Radiation therapy after lumpectomy lowers the risk of breast cancer recurrence and may increase the chances of survival [4]. It's usually recommended after lumpectomy. Radiation therapy for early breast cancer most often involves treatment once a day, 5 days a week, for 1-6 weeks.
How long are radiation treatments for DCIS?
A typical course of radiation treatment for DCIS involves 16 sessions given over three weeks.
How many rounds of radiation is normal for breast cancer?
A common treatment schedule (course) historically has included one radiation treatment a day, five days a week (usually Monday through Friday), for five or six weeks. This course is still commonly used in people who require radiation to the lymph nodes.
How much does radiation reduce recurrence of DCIS?
The researchers found that the women who got radiation therapy were 48% less likely to have a local recurrence of DCIS than women who didn't get radiation therapy: 18% of the women who had lumpectomy and radiation therapy had a local recurrence.
How many sessions of radiotherapy is normal?
Most people have 5 treatments each week (1 treatment a day from Monday to Friday, with a break at the weekend). But sometimes treatment may be given more than once a day or over the weekend.
How long are radiation treatments?
Each radiation therapy treatment takes about 10 minutes. Radiation therapy to try and cure cancer is usually delivered daily, Monday through Friday, for about five to eight weeks. Weekend breaks allow normal cells to recover. Shorter durations of radiation therapy may be used to relieve symptoms.
How long do you have radiotherapy for breast cancer?
If you need radiotherapy, your treatment will begin about a month after your surgery or chemotherapy to give your body a chance to recover. You'll probably have radiotherapy sessions 3 to 5 days a week, for 3 to 5 weeks. Each session will last a few minutes.
What is the success rate of radiation therapy for breast cancer?
Radiation therapy decreased the risk of dying from cancer by approximately 33%. The probability of surviving 10 years from treatment was increased from 54% to 64% and 45% to 54% in the two studies, respectively. No significant long-term side effects of radiation therapy were reported.
Is radiation necessary after lumpectomy for DCIS?
Radiation is typically used after lumpectomy. But it might not be necessary if you have only a small area of DCIS that is considered low grade and was completely removed during surgery.
Can you get breast radiation twice?
So that our current understanding is that, except for very unusual situations, we would not give a radiation to a previously treated area, because of the concern about a much higher rate of complication. So, the answer is: no, we would, in most circumstances, not re-treat a previously treated area.
How often does DCIS come back?
Will DCIS return or spread? Since DCIS is a noninvasive form of cancer, it does not spread throughout the body (metastasize). For patients having a lumpectomy with radiation, the risk of local recurrence ranges from 5% to 15%. For those having mastectomy, the risk of local recurrence is less than 2%.
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.
Do you lose weight during radiation treatment?
Many cancer patients lose weight unexpectedly during radiation therapy because they struggle with side effects caused from treatment. Maintaining proper nutrition during radiation therapy can increase your chances of successful treatment and improve your quality of life during and after treatment.
Do you lose your 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.

Your doctor or nurse will share strategies that have help others, including those listed below.
Is radiation necessary after lumpectomy for DCIS?
Radiation is typically used after lumpectomy. But it might not be necessary if you have only a small area of DCIS that is considered low grade and was completely removed during surgery.
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 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 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 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.
What is lumpectomy surgery?
A lumpectomy involves removing the cancer and some of the healthy tissue that surrounds it. This illustration shows one possible incision that can be used for this procedure, though your surgeon will determine the approach that's best for your particular situation.
What is clinical trial?
Clinical trials are studying new strategies for managing DCIS, such as close monitoring rather than surgery after diagnosis. Whether you're eligible to participate in a clinical trial depends on your specific situation. Talk with your doctor about your options.
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.
What is a DCIS?
Treatment of Ductal Carcinoma in Situ (DCIS) Ductal carcinoma in situ (DCIS) means the cells that line the milk ducts of the breast have become cancer, but they have not spread into surrounding breast tissue. DCIS is considered non-invasive or pre-invasive breast cancer.
What is BCS in surgery?
Breast-conserving surgery (BCS) In breast-conserving surgery (BCS), the surgeon removes the tumor and a small amount of normal breast tissue around it. Lymph node removal is not always needed with BCS, but it may be done if the doctor thinks the area of DCIS might also contain invasive cancer.
Does DCIS have invasive cancer?
The chances an area of DCIS contains invasive cancer goes up with tumor size and how fast the cancer is growing. If lymph nodes are removed, this is usually done as a sentinel lymph node biopsy (SLNB ). If BCS is done, it is usually followed by radiation therapy. This lowers the chance of the cancer coming back in the same breast ...
Is DCIS invasive or noninvasive?
DCIS is considered non-invasive or pre-invasive breast cancer. DCIS can’t spread outside the breast, but it still needs to be treated because it can sometimes go on to become invasive breast cancer (which can spread).
Can you get BCS without radiation?
BCS without radiation therapy is not a standard treatment, but it might be an option for certain women who had small areas of low-grade DCIS that were removed with large enough cancer-free surgical margins.
Can you do SLNB after mastectomy?
This is because if an area of invasive cancer is found in the tissue removed during a mastectomy, the doctor won’t be able to go back and do the SLNB later, and so may have to do a full axillary lymph node dissection (ALND).
Can a BCS remove DCIS?
Simple mastectomy (removal of the entire breast) may be needed if the area of DCIS is very large, if the breast has several separate areas of DCIS, or if BCS cannot remove the DCIS completely (that is, the BCS specimen and re-excision specimens still have cancer cells in or near the surgical margins).
How to make an appointment for radiation therapy for ductal carcinoma in situ?
Patients interested in radiation therapy for ductal carcinoma in situ can request an appointment by calling 1-888-663-3488, or by submitting a new patient registration form online.
Can you get radiation therapy for milk duct cancer?
In many cases, radiation therapy is recommended after surgery; even though it’s often possible to remove all of the cancerous cells from the milk ducts through a lumpectomy or mastectomy, radiation therapy can help ensure that the entire malignancy has been destroyed.
Does radiation help with breast cancer?
Even when a patient has all of his or her breast tissue removed, radiation therapy may still be recommended to help reduce the risk of the cancer coming back. Some studies suggest that radiation therapy for ductal carcinoma in situ can reduce the risk of recurrence by up to 60 percent – a statistic that leads many patients to choose post-operative ...
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.
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.
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 you have a sentinel node biopsy after a mastectomy?
Once a mastectomy has been done, a person can’t have a sentinel node biopsy. If it turns out there’s invasive breast cancer (along with DCIS) in the tissue removed during the mastectomy, a sentinel node biopsy will have already been done.
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.
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.
Can radiation therapy be given for DCIS?
Radiation therapy isn’t given to people who are treated with mastectomy for DCIS. Lumpectomy for DCIS is usually followed by radiation therapy to lower the risk of [1]: DCIS recurrence (a return of DCIS) in the treated breast. Invasive breast cancer in the treated breast.
Is ductal carcinoma in situ invasive?
Introduction: Ductal carcinoma in situ (DCIS) is a non-invasive breast cancer. Without treatment, DCIS can progress to invasive breast cancer over time. So, almost all cases of DCIS are treated. Treatment involves surgery, with or without radiation therapy.
