How long does DCIS take 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.

Do I need surgery for DCIS?
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).
How serious is DCIS with Microinvasion?
Synopsis. DCIS with microinvasion is a rare diagnosis with an excellent prognosis and a low rate of nodal involvement. This study attempts to identify factors associated with a positive sentinel lymph node biopsy and provides outcome data on these patients.
Is DCIS with Microinvasion curable?
Conclusion. Microinvasive carcinomas are distinct from DCIS in terms of clinicopathological features and biomarker expressions but are similar to DCIS in terms of clinical outcomes. Our results suggest that microinvasive carcinoma can be treated and followed up as pure DCIS.
What is the treatment for DCIS with Microinvasion?
(See "Microinvasive breast carcinoma".) TREATMENT APPROACH Patients with DCIS undergo local treatment with breast-conserving therapy (BCT) or mastectomy. BCT consists of lumpectomy (also called breast-conserving surgery, wide excision, or partial mastectomy) followed in most cases by adjuvant radiation.
What does Microinvasion mean?
[ mī′krō-ĭn-vā′zhən ] n. Invasion of in situ carcinoma into tissue that is immediately adjacent, being the earliest stage of malignant neoplastic invasion.
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.
How long does it take 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.
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.
Does size of DCIS matter?
Tumor Size Matters One important factor in that calculation is the size of the DCIS, says Dr. White. "With DCIS lesions [bigger] than 20 to 25 millimeters, the general recommendation is for more than just surgery," she says. That additional treatment may include radiation and hormone therapy.
Can DCIS spread after biopsy?
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%.
What is the survival rate for DCIS?
Generally, patients diagnosed with DCIS have an excellent long-term breast-cancer-specific survival of around 98% after 10 years of follow-up24–27 and a normal life expectancy.
What percentage of DCIS is high grade?
We found that 50.9 % of all DCIS detected by mass screening are high grade, and therefore have a high risk of progression.
Is DCIS 100 curable?
Many women — perhaps assuming all breast cancers are dangerous — may believe that removing the healthy breast after a diagnosis of DCIS improves their chances of survival. But DCIS is nearly 100 percent curable.
What is the survival rate for DCIS?
Generally, patients diagnosed with DCIS have an excellent long-term breast-cancer-specific survival of around 98% after 10 years of follow-up24–27 and a normal life expectancy.
What percentage of DCIS is high grade?
We found that 50.9 % of all DCIS detected by mass screening are high grade, and therefore have a high risk of progression.
What does high grade DCIS mean?
High-grade DCIS has a higher risk of coming back than low- or moderate-grade DCIS. High-grade DCIS may be described as comedo or comedo necrosis, which means there are areas of dead cancer cells inside the DCIS.
What is focal Microinvasion?
“Microinvasion” is a term used somewhat informally to describe a borderline difference between completely contained ductal carcinoma in situ (DCIS) (early-stage breast cancer) and a minimally invasive ductal carcinoma.
Specific criteria for defining microinvasive breast cancer are varied
Microinvasive ductal carcinoma has been referred to by a variety of names, including Microinvasive breast carcinoma (MIC), ductal carcinoma in situ with microinvasion (DCISM or DCIS-MI), Microinvasive carcinoma of the breast (MICB), DCIS with microinvasion or simply microinvasive breast carcinoma (cancer), sometimes identified by the ‘ breast cancer staging ‘ abbreviation Tmic (which means that a tumor is present, and some microinvasion is also present but with a very small diameter)..
Improvements in Breast Cancer screening mammography has lead to increased detection of microinvasive DCIS
Improvements in the quality and interpretation of breast cancer screening mammograms, as well as a general increase in the number of women participating in breast cancer screening programs, has lead to an increase in findings of ductal carcinoma in situ, with a corresponding increase in Ductal carcinoma in situ (DCIS) with evidence of microinvasion.
Histological analysis of suspected microinvasive DCIS tumors can help clarify the diagnosis
Since treatment for ‘pure’ DCIS (fully contained within the breast ducts) differs or may differ from DCIS with microinvasive status, identifying the smallest focus or foci of any invasive carcinoma is of some significance.
Staging and treatment of microinvasive breast cancer : Is Axillary lymph node investigation necessary?
Staging of microinvasive ductal carcinoma in situ is somewhat of a controversial topic. The general consensus surrounding ‘pure’ ductal carcinoma in situ is that axillary lymph node metastasis is so very improbable that lymph node staging or sentinel lymph node biopsy are not necessary.
The prognosis for microinvasive carcinoma of the breast is very good
There is universal agreement that the prognosis for ductal carcinoma discovered and intervened at a ‘microinvasive’ stage, is very good. Patients with microinvasive breast cancer can typically expect a cure rate very close to 100%, with local treatment alone.
DCIS recurrence risk factors
DCIS can be eliminated with mastectomy, but this is considered overtreatment in many cases for a condition that is not life threatening and might not progress to invasive cancer. In fact, women who are treated for DCIS with mastectomy of the affected breast remain at ongoing risk of a recurrence of DCIS in the opposite breast.
Risk factors for progression of DCIS to invasive breast cancer
Factors associated with progression to invasive breast cancer similar but not identical to those associated with recurrent DCIS.
Tamoxifen and aromatase inhibitors reduce progression
Tamoxifen and aromatase inhibitors have both been found to reduce both DCIS recurrence and progression to invasive breast cancer among women with estrogen receptor positive DCIS.
Increased likelihood of additional screening and procedures
The risk of DCIS recurrence or progression to invasive cancer continues at least 20 years and requires active ongoing follow up. Some women face multiple additional diagnostic tests and invasive procedures over time after breast conserving treatment for DCIS.
Radiation treatment might be associated with different pattern of recurrence
One controversial 10-year prospective study found that patterns of recurrence were different for women who had radiation treatment compared to those who did not. The study followed 1,000 patients with pure DCIS who underwent breast-conserving surgery with or without radiation.
surgery options for high grade DCIS with microinvasion
I was recently diagnosed with high grade DCIS with microinvasion. The initial diagnosis was for straightforward DCIS, but a second biopsy after an MRI showed it to be more advanced, with a smaller secondary lesion. The whole area that needs to be removed is approx 4cms.
surgery options for high grade DCIS with microinvasion
I am sorry to hear that you find yourself in this predicament. I lost both parents, many family and close friends to cancer myself. I then got a diagnosis of breast cancer 8 years ago and had a lumpectomy, followed by Tamoxifen. A year later I had a second bout in the same breast.
Staging and treatment options for high grade DCIS
There is no clear consensus at to what to do with DCIS. Evidence from microcalcifications and histological evaluation will give a better indication of cancer staging, aggressiveness and management.
The Van Nuys Pronostic Index (VNPI)
Treatment options for DCIS are sometimes evaluated using the Van Nuys Prognostic Index (VNPI). It assesses the risk of recurrence on a scale of 1 to 3 and considers diagnostic factors such as the tumor size, width of resection margins, presence of necrosis ( dead cells and debris ), and nuclear grade.
