To do the study, the researchers looked at the records of 5,916 Missouri women who were diagnosed with DCIS from 1996 to 2011 and had lumpectomy. The researchers considered having radiation therapy within 8 weeks of surgery to be timely with no delay. While most of the women had radiation with no delay, nearly 50% did not:
How quickly should women with DCIS have radiation therapy?
Radiation therapy after lumpectomy reduces the chance that DCIS will come back (recur) or that it will progress to invasive cancer. Radiation most often comes from a machine that moves around your body, precisely aiming the beams of radiation at points on your body (external beam radiation).
How is radiation therapy used to treat DCIS after lumpectomy?
DCIS is treated to try to prevent the development of invasive breast cancer. DCIS can be found alone or with invasive breast cancer. If DCIS is diagnosed with invasive breast cancer, treatment and prognosis are based on the invasive breast cancer (not the DCIS). Learn about treatment for early breast cancer.
What is DCIS and how is it treated?
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.
What are the advantages of radiation for DCIS?
How long is radiation treatment after lumpectomy?
The standard radiation therapy approach after a lumpectomy has been to target the entire breast. The method is called whole-breast irradiation. It is typically given every day for four to six weeks.
How long is radiation therapy given?
How long does radiation therapy take? 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.
How long is each radiation session for breast cancer?
Delivery of the radiation may last only a few minutes, but expect to spend 15 to 45 minutes for each session, as it can take several minutes to set you up in the exact same position each day. This step ensures precise radiation therapy delivery. Radiation therapy is painless.
How many days a week is radiation therapy for breast cancer?
The standard schedule for getting whole breast radiation is 5 days a week (Monday through Friday) for about 6 to 7 weeks.
How many sessions of radiation therapy are there?
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.
Is 6 weeks of radiation a lot?
Treatments are usually given five days a week for six to seven weeks. If the goal of treatment is palliative (to control symptoms) treatment will last 2-3 weeks in length. Using many small doses (fractions) for daily radiation, rather than a few large doses, helps to protect the healthy cells in the treatment area.
How many days a week is radiation therapy?
Most patients get radiation treatments daily, 5 days a week (Monday through Friday) for 5 to 8 weeks. Weekend rest breaks allow time for normal cells to recover.

What can you not do during radiation treatment?
Avoid raw vegetables and fruits, and other hard, dry foods such as chips or pretzels. It's also best to avoid salty, spicy or acidic foods if you are experiencing these symptoms. Your care team can recommend nutrient-based oral care solutions if you are experiencing mucositis or mouth sores caused by cancer treatment.
How long does each radiation session take?
Expect each treatment session to last approximately 10 to 30 minutes. In some cases, a single treatment may be used to help relieve pain or other symptoms associated with more-advanced cancers. During a treatment session, you'll lie down in the position determined during your radiation simulation session.
Can you skip a day of radiation?
Answer: Missing one day or even two days in a row over the course of a six-to-eight-week course of radiation really doesn't matter. But we do know from studies that have been done in the past that if radiation is given with a significant stop in the middle -- a week or two weeks -- it actually is less efficient.
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 ...
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.
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 ...
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.

What is a DCIS?
DCIS (ductal carcinoma in situ) is the most common form of non-invasive breast cancer and is considered stage 0 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.

Radiation therapy after DCIS surgery was common in the past, but some newer DCIS treatment guidelines say that women at low risk of recurrence (the cancer coming back) may be able to skip radiation therapy after surgery.
Does radiation reduce the risk of recurrence in the same breast?
Several other large, randomized studies have shown that radiation after lumpectomy for DCIS reduces the risk of recurrence in the same breast by about half. Other studies have shown that taking tamoxifen after lumpectomy for hormone-receptor-positive DCIS reduces the risk of both DCIS recurrence and invasive disease in both breasts.
Does radiation therapy after lumpectomy reduce risk of recurrence?
Now a study has found that radiation therapy after lumpectomy to remove low-risk DCIS reduces the risk of recurrence, but had no effect on overall survival. The research was presented on Oct. 21, 2018, at the American Society for Radiation Oncology Annual Meeting.
Does radiation help with DCIS?
Still, no study has shown that radiation or tamoxifen after lumpectomy for DCIS improves overall survival or reduces the rate of metastatic recurrence (cancer coming back in a part of the body away from the breast). How DCIS considered to have a low risk of recurrence should be treated is somewhat controversial right now.
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.
What is the best treatment for DCIS after surgery?
After surgery, hormonal therapy may be recommended if the DCIS is hormone-receptor-positive (most are). Radiation therapy also is recommended for many women. Both hormonal therapy and radiation help reduce the risk of the DCIS recurring (coming back), as well as the risk of invasive cancer.

Is DCIS invasive?
As opposed to invasive breast cancers, DCIS cancers are confined to the local area and have not spread to deeper tissues or elsewhere in the body. With increased rates of diagnosis, there has been considerable controversy about the true risks of DCIS and the best treatments, with some suggesting that women are being overtreated for a condition ...
Should DCIS patients continue to have breast cancer?
While no details on surveillance strategies, such as regular mammograms or other exams, were presented in this study, based on these results, patients with DCIS should continue active surveillance for breast cancer for decades after their diagnosis.
