Ductal Carcinoma in Situ (DCIS) is a condition where the cells lining the milk ducts (the channels in the breast that carry milk to the nipple) are cancerous, but stay contained within the ducts without growing through into the surrounding breast tissue. DCIS may affect just one area of the breast, but can be more widespread and affect different areas at the same time. Sometimes DCIS may be described as pre-cancerous, pre-invasive, non-invasive, or intraductal cancer.
A new study of women with early stage, localized breast cancer identifies new patterns and risk factors for invasive disease that may influence how patients are treated.
Inflammation cuts both ways. When invaded by an infectious agent, for example, the body calls on the forces of inflammation to fight and defeat the intruder.
Certain breast lesions diagnosed as benign on core needle biopsy have cancer at surgical excision and thus should be removed, according to a study appearing in the March issue of Radiology.
Researchers have found that mammography coupled with magnetic resonance imaging (MRI) is extremely sensitive in the detection of ductal carcinoma in situ (DCIS). DCIS, or early stage breast carcinoma, is a pre-invasive malignancy and MRI may help identify this type of disease, which may not be visible on a mammogram.
Johns Hopkins Kimmel Cancer Center researchers are studying whether delivering chemotherapy drugs directly to breast "plumbing" might make treatment of early breast cancer easier on the patient and at least as good as surgery or radiation.
A gene that appears to help regulate normal embryonic development is found at high levels in virtually all forms of breast cancer, according to a new study led by Laszlo Radvanyi, Ph.D., associate professor of breast and melanoma medical oncology at The University of Texas M. D. Anderson Cancer Center.
Using a super-efficient method they invented to search for a type of cancer-related change in all genes of a cell, Dana-Farber Cancer Institute researchers have discovered new evidence about how the "microenvironment" of breast cancers helps drive the cancers' growth and migration.
New research suggests that there is a direct relationship between the density of breast tissue, and the risk of developing tumours in dense areas of the breast.
Since 1980, the incidence of ductal carcinoma in situ, or DCIS, one of the most common kinds of early stage breast cancer, has increased more than sevenfold. This sharp increase in DCIS – which is a tumor that contains cancer-like cells but is not considered "true" cancer because the cells have not invaded normal breast tissue – has been accompanied by a flattening in the incidence of true invasive breast cancer.
The inherited breast/ovarian cancer genes are BRCA1 and BRCA2, which are associated with an increased risk of breast and/or ovarian cancer. The results are part of a five–year study of a common form of early stage breast cancer called ductal carcinoma in situ (DCIS).
Women diagnosed with early stage, non–invasive breast cancer who carry the same mutations in two inherited breast/ovarian cancer genes as women diagnosed with invasive breast cancer, may benefit from high risk treatment, Yale researchers report in the February 23 issue of Journal of the American Medical Association.
In women with breast lesions that are suspicious for cancer, based on clinical examination or mammography, performing a breast MRI has high sensitivity but only moderate specificity for detecting breast cancer, but does not necessarily eliminate the need for tissue sampling, according to a study in the December 8 issue of JAMA.
Advances in biomedical imaging are allowing UC Davis researchers to use mice more effectively to study cancers comparable to human disease. The system can distinguish different stages of cancer and could lead to more sensitive screening tests for cancer-fighting drugs.
In the first comprehensive survey of gene activity in each cell type composing normal and malignant breast tissue, scientists at Dana-Farber Cancer Institute have identified genes in non-cancerous supporting cells that can spur the growth of breast cancer cells.
Researchers at Virginia Commonwealth University’s Massey Cancer Center have begun a clinical trial testing the effectiveness of an established balloon catheter radiation delivery device on the earliest form of breast cancer, ductal carcinoma in situ.
Treatment of ductal carcinoma in situ (DCIS), a group of abnormal cells confined to the breast ducts, varies widely in the United States. Treatment ranges from potential over-treatment with aggressive surgical therapy to possible under-treatment by not providing radiation.
