Duktalkarcinoma in situ (CDIS) is a very early type of breast cancer, which is about 1 in 5 cases of breast cancer.
While a cancer diagnosis is creepy, the CDIs is not invasive and very treatable. The panorama is excellent with adequate treatment and surveillance. And the five -year survival rate for people with CDIS diagnoses is 98%.
What is the CDIS?
The CDIs is the earliest stage of breast cancer, sometimes known as the breast cancer stage.
The term ducal carcinoma in situ is somewhat confusing. That means:
- Duktal: Cancer can be found in the cells that cover the chest channels. It could be in one or both breasts.
- Carcinoma: These ductal cells become abnormal (cancer -like).
- In situ: Cancer remains “at the point” where he comes. It could spread to more ductal cells, but it does not spread to other areas.
The CDIS is not invasive, which means that it has not spread the place where it comes, but it still has to be. While the CDIs have an excellent forecast, studies show that people with CDIs diagnoses have a higher risk of later developing invasive cancer. Between 20 and 50% of the CDIs cases could be the forerunners of a more advanced stage of breast cancer.
Providers of medical care cannot determine which cases will progress more advanced. The safest method is to treat all cases of CDIs quickly. Treatment of the CDIs provides intensively better clinical results and reduces the risk of subsequent invasive cancer.
CDIS symptoms and diagnoses
The CDIs usually cause symptoms that can be noticed. Some people could notice a dough in their mother, skin irritation or itching, pain or secretion of the nipple. But that doesn’t happen often. Most of the time, the CDIs are detected in mammographies, these regular examinations are important!
If you have CDIs, mammogram can show microcalcocifications clusters. These clusters are calcium deposits in the chest. You could be there for many reasons. In fact, they are very common in women over 50 years. However, certain micro -list patterns could indicate an early cancer stage. As a result, more imaging tests are required in your mammogram.
If you have CDIS signals, your Medical Care Provider (HCP) may need one or more of the following tests:
- Diagnostic mammography: offers more detailed X beam images of the breast than a mammogram, often from different angles or positions.
- Ultrasound: Sound waves are used to get pictures of the breast tissue. Sometimes ultrasound are used to lead biopsies.
- Breast -RM: Magnetic resonances are more sensitive than mammograms or ultrasound.
After imaging, the next step is a biopsy: a small part of the breast tissue is extracted and then analyzes a pathologist. The analysis determines the type of CDIS and the best treatment plan.
Different types of CDs
The CDIS is classified with a so -called core degree. The “classifying” scale or evaluates the occurrence of cancer cells compared to normal breast cells. The cells can be low, medium or high degrees. A larger degree means that cancer cells are more abnormal and more accelerated.
It is also important to determine the hormonal composition of cancer cells. This is useful for doctors to determine the best therapeutic method. Some cancer cells have hormonal estrogen or progesterone receptors. Having these receptors is cheap. This means that cancer grows more slowly and depends on hormones to survive. Most CDIs cases have hormonal receptors.
How is the CDIS?
CDIS treatment is usually simple: operation, often followed by radiation therapy. Radiation guarantees that all cancer cells are eliminated. In some cases, hormonal therapy could be recommended. Chemotherapy is not used to treat CDIs.
- OperationsPartial mastectomy is also known as tumorectomy or surgery with breast preservation. The surgeon removes breast tissue. The fabric includes cancer cells and a little healthy tissue that lies in the area. The chest itself is not removed.
A mastectomy is an operation that removes the entire tissue or the entire breast. The patients were able to opt for a breast reconstruction operation after the mastectomy.
The necessary operation depends on the spread of the CDIs. If cancer is in a small and contained area, it is usually possible to carry out a partial mastectomy. If cancer spreads or spreads through ductal cells, mastectomy is required.
- radiotherapyRadiation therapy uses high energy rays, usually X rays to eliminate cancer cells that were not removed during the operation. It is associated with a lower risk of recurrence.
- Hormonal terpiaIf cancer cells have hormonal receptors, your medical provider can recommend hormonal therapy that is useful to prevent recurrence. If you have submitted a mastectomy, hormonal therapy is usually not necessary.
Did the CDIs repeat?
While the CDIs can reappear, their repetition rate is low. For people who undergo partial mastectomy, followed by radiation therapy, it is less than 15%.
The degree of CDIs also affects the repetition rate. A lower degree corresponds to a lower risk of recurrence. However, the risk of recurring is greater for black women than for Asian, Hispanic or White Women. This could be due to the fact that white women benefit from more surveillance through imaging controls. These systemic racial or ethnic differences have fatal consequences: the breast cancer rate according to CDIs is larger for black women.

The regular structure of mammograms is useful to recognize CDIs and treat them quickly. After completing the treatment for CDIs, the examinations are regularly useful to recognize abnormality. With good persecution, you have everything on your side to stay healthy after a CDIS diagnosis.
