Prevalence And Association With Ductal Carcinoma In Situ
Microinvasive carcinoma of the breast represents less than 1% of all breast cancer types. It is commonly associated with ductal carcinoma in situ (DCIS), a non-invasive form of breast cancer. It is estimated that 5-10% of DCIS cases may have microinvasion.
DCIS refers to abnormal cells that are confined to the milk ducts and have not spread into surrounding tissue. The presence of DCIS increases the risk of developing microinvasive carcinoma.
This association highlights the importance of early detection and treatment of DCIS to prevent its progression to a more invasive form of breast cancer.

You may need to know these questions about micro-invasive carcinoma
What is micro invasive carcinoma?
Microinvasive carcinoma, also known as DCIS with microinvasion, refers to invasive breast cancer where the invasive focus does not exceed 1 mm in size. This type of carcinoma is frequently associated with ductal carcinoma in situ (DCIS). Although considered invasive, microinvasive carcinoma typically exhibits limited invasion, making it distinct from larger invasive breast cancers.
Microinvasive carcinoma occupies a unique place in the spectrum of breast cancer, as it combines characteristics of both DCIS and invasive carcinoma. While DCIS remains confined within the ducts, microinvasion demonstrates a small degree of invasive growth. The identification of microinvasion is crucial as it influences the management and treatment decisions for patients. Understanding the nuances of microinvasive carcinoma helps clinicians determine the appropriate course of action and ensures optimal patient care.
Can Microinvasive cancer spread?
Microinvasive carcinoma refers to early-stage cancer that has not yet infiltrated surrounding tissues deeply. In some cases, it is possible for microinvasive cancer to spread to other parts of the body, specifically the axillary lymph nodes. However, the incidence of lymph node metastasis in such cases is relatively low, ranging from 0% to 20%. While microinvasive cancer has the potential to spread, the likelihood of metastasis appears to be relatively limited. Close monitoring and appropriate treatment can help mitigate the risk of further dissemination.
How is micro invasive carcinoma treated?
Microinvasive carcinoma, also known as minimal invasive carcinoma, typically requires a multidisciplinary treatment approach. The primary treatment options for microinvasive carcinoma include breast-conserving therapy (BCT) and mastectomy. BCT involves lumpectomy, a procedure that removes the tumor while preserving the rest of the breast. Following lumpectomy, adjuvant radiation therapy is commonly administered to ensure local disease control. Mastectomy, on the other hand, involves the complete removal of the breast tissue and may be considered in cases where there is a higher risk of recurrence or if the tumor is more extensive. Regardless of the chosen approach, a comprehensive assessment and consultation with a healthcare team will help determine the most suitable treatment plan for each individual case.
Is Microinvasive breast cancer curable?
Microinvasive breast cancer has a high likelihood of cure. With an overall 5-year survival rate of around 95% or higher, the prognosis for women diagnosed with this type of carcinoma is generally promising. Early detection and advancements in treatment options, such as surgery, radiation therapy, and targeted therapies, contribute to the high curability of microinvasive breast cancer. While individual cases may vary, the overall prognosis for those diagnosed with this condition indicates a positive outcome, offering hope and optimism to patients and their loved ones.
