There are many factors that influence breast density including age, hormone levels, genetics, age at first pregnancy, number of pregnancies, use of hormone replacement therapy, and overall body weight — just to name a few. This makes it more difficult for doctors to see potential breast cancer. Mastitis Paget's disease of the breast Palliative care: Mammograms can help your doctor identify breast cancer. Even if you have a normal mammogram result regardless of how dense your breasts are , you should know how your breasts normally look and feel. The amount of radiation exposure is higher with tomosynthesis compared to standard digital mammography, but is lower than with the older film screen technology. Dense breast tissue makes it more difficult to interpret a mammogram, since cancer and dense breast tissue both appear white on a mammogram.
What is dense breast tissue?
Breast Density and Your Mammogram Report
Breast cancer risks and detection This podcast share more information on breast cancer risks and detection. Next, Section 3 includes a description of the system structure and operation, and also of the experiments devised. While there are no ways to prevent dense breast tissue from developing, a woman can engage in lifestyle choices that help her to reduce her risk for breast cancer. For each abnormality identified within which masses are included , the radiologists draw free form digital curves defining ground truth regions. For a density value equal to 3, this sum is always significantly lower than the number of normal tissue prototypes.
Dense Breasts - Diagnosis, Evaluation and Treatment
These average values are shown for the overall experiment, and for the experiments with a given value of density. The mammogram will show what kind of tissues are dominant in your breasts. The risk of breast cancer actually increases with age, and it is hard to sort out when the increased risk as it relates to breast density develops. View at Google Scholar C. The majority of women diagnosed with breast cancer have no known family history or other risk factors. The study was done with a total of prototypes: Breasts that are not dense contain almost all fatty tissue and very little fibrous tissue.
Then, in , researchers reported findings that suggested breast density not only made it harder to find cancers, but was also was as an independent predictor of breast cancer risk. For example, in the training subset this sum is equal to An ultrasound that uses sound waves, no additional radiation, something even pregnant women have as a usual screening. In each of the experiments we made the same tests, but with different sets of prototypes: The generated regions have different sizes but the selected image feature extractor needs to operate on regions with the same size, so we need to reduce the size of the selected regions to common sizes. One theory is that a protein, which sits on the surface of tumour cells, binds to collagen rather than fat and starts to spread the cancer. Nancy Campbell spent seven years exploring the Arctic and learnt that ice can teach us about our history, as well as our future.
