Ductal carcinoma in situ is an extremely early form of breast cancer. When it occurs, the cancer cells are contained within a breast milk duct, and the surrounding breast tissue remains free of cancerous cells. A common term for this type of breast cancer is DCIS. This type of breast cancer is sometimes referred to as stage 0, noninvasive, or preinvasive.
DCIS is usually found on a mammogram that is done to screen for breast cancer or to investigate a lump in the breast. There is a minimal chance that DCIS will become invasive and threaten life. However, it must be evaluated, and treatment options must be considered.
DCIS is often treated with surgery. Other treatments may include hormone therapy or radiation therapy in addition to surgery.
Ductal Cell Carcinoma in Situ (DCIS) must be treated early to lower the chance of recurrence and spread to other body areas, as well as to stop it from developing into invasive breast cancer. Early detection reduces the psychological and physical effects of more invasive surgeries, increases survival rates, and permits breast-conserving therapy. Patients who receive immediate treatment for DCIS have a better prognosis and a higher quality of life, and their chances of the disease developing into something invasive or life-threatening are significantly decreased.
Typically, ductal carcinoma in situ does not exhibit any symptoms. DCIS is another name for this early stage of breast cancer.
DCIS can occasionally result in symptoms like:
Mammography is typically where DCIS is detected. In breast tissue, it manifests as microscopic calcium particles. These are calcifications, which are deposits of calcium.
Causes
Risk Factors
In Singapore, the approach to treating Ductal Carcinoma In Situ (DCIS) has undergone significant evolution, thanks to advancements in technology and enhanced clinical practices. Surgical interventions, including lumpectomy and mastectomy, are still at the forefront of treatment, often accompanied by radiotherapy to help minimise the risk of recurrence. The adoption of oncoplastic surgery techniques enables effective tumour removal while preserving the breast's aesthetic qualities. Furthermore, cutting-edge technologies such as augmented reality microscopes and deep learning-based grading systems are enhancing the precision and reliability of histopathological evaluations. These innovations are focused on personalising treatments, reducing the likelihood of overtreatment, and ultimately improving outcomes for patients.
Lumpectomy: The breast cancer and a portion of the surrounding normal tissue are cut out during a lumpectomy. There is no removal of the rest of the breast tissue. Wide local excision and breast-conserving surgery are alternative names for this procedure. Most patients who have a lumpectomy also undergo radiation therapy.
Mastectomy: The removal of all the breast tissue by operation is called a mastectomy. If you prefer, breast reconstruction to re-form the appearance of the breast may be performed at the same time or later on.

Hormone therapy: Endocrine therapy, also referred to as hormone therapy, involves using drugs that prevent the body from making specific hormones. It is applied in the treatment of breast cancers that are estrogen and progesterone-sensitive.

Radiation Therapy: To reduce the risk of recurrence, radiation therapy is often given after surgery for ductal carcinoma in situ (DCIS). It is typically recommended following a lumpectomy, especially if the tumour is large or has high-risk features. High-energy X-rays are employed in the treatment to locate and kill any remaining cancer cells in the breast tissue. Radiation therapy significantly decreases the possibility that DCIS could recur.

Singapore is an excellent destination for treating ductal carcinoma in situ (DCIS) due to its world-class medical infrastructure, highly trained medical professionals, and access to the latest technologies. The country offers comprehensive care tailored to each patient's specific needs, including radiation therapy, surgery, and targeted therapies. Singapore is also a favoured destination for high-value care because the cost of medical care is often lower compared to other countries.
Yes, mammography can often detect ductal carcinoma in situ (DCIS). DCIS usually appears as microcalcifications, microscopic calcium deposits that appear as white specks on X-rays. Microcalcifications can also occur with benign conditions, but when they occur in specific patterns, they can be a marker for DCIS. Mammograms are a key early detection method for DCIS, often before symptoms develop.
In Singapore, a biopsy is the gold standard for diagnosing ductal carcinoma in situ (DCIS). While mammograms and other imaging tests can identify problematic spots, a biopsy is necessary to collect a tissue sample for microscopic analysis. Doctors can use this to effectively diagnose DCIS, evaluate its features, and choose the best course of treatment.
In Singapore, ductal carcinoma in situ (DCIS) often needs surgery, although this depends on the individual case. Based on the size, location, and other features of the DCIS, the most frequent surgical options are mastectomy (breast removal) or lumpectomy (tumour removal).
Surgery is not always needed for DCIS, especially if the issue is detected early and can be treated with hormone therapy or radiation. After consulting with the medical team, the choice is made based on the patient's condition and personal preferences.
Mastectomy can be suggested for Ductal Carcinoma In Situ (DCIS) in Singapore if the DCIS is extensive or widespread or if it occurs in several locations within the breast, so that breast-conserving surgery, such as lumpectomy, is not as effective. It can also be suggested if the patient is at high risk of recurrence or if prior surgery has not worked to remove the cancer.
Radiation therapy is often recommended in Singapore’s healthcare environments for ductal carcinoma in situ (DCIS), particularly after a lumpectomy. It targets any remaining breast cancer cells, reducing the risk of recurrence. However, radiation therapy is not required for all DCIS patients. Tumour size, margins, grade, and other risk factors affect the decision.
In Singapore patients, ductal carcinoma in situ (DCIS) may recur after treatment; the risk is low if proper treatment is undertaken. The opposite or the same breast (local recurrence) can suffer from recurrence. Several factors, including the grade of DCIS, surgical margins, radiation therapy application, and the patient's overall condition, can influence the risk of recurrence. Imaging tests, monitoring, and follow-up treatment are essential in detecting early recurrence.
Over the years, the survival rate for breast cancer has seen a significant boost due to advancements in treatment options and the ability to catch it early. For instance, patients diagnosed with Stage I breast cancer enjoy a remarkable 90% survival rate over five years. In contrast, those facing Stage II breast cancer have an 80% survival rate for the same period, as highlighted in a 2017 report from the Singapore Cancer Registry.
