INTRODUCTION:
The term “breast cancer” refers to a malignant tumor that has developed from cells in the breast. Usually breast cancer either begins in the cells of the lobules, which are the milk-producing glands, or the ducts, the passages that drain milk from the lobules to the nipple. Less commonly, breast cancer can begin in the stromal tissues, which include the fatty and fibrous connective tissues of the breast.
In India, 144,937 women were newly detected with breast cancer and 70,218 women died of breast cancer in 2012. For every 2 women newly diagnosed with breast cancer, one lady is dying of it. Incidence of breast cancer has also increased from 25.9% in the year of 2008 to 27% in 2012.In the year 2012, there were about 2, 32,000 breast cancer cases reported in the US, whereas in India, 1,45,000 new cases were diagnosed. This implies that, though, because of India's population, the percentage of total women affected seems less, the breast cancer burden in India has almost reached about 2/3rds of that of the US and is steadily rising. For the years 2015, there will be an estimated 1, 55,000 new cases of breast cancer and about 76000 women in India are expected to die of the disease.
Best “treatment” of cancer is preventing its occurrence in the first place or detecting it early when it may be most treatable. Mammogram screening is the best way of testing breast cancer in persons who do not have any symptoms of a cancer but are at high risk for breast cancer [23]. A mammogram helps to reveal irregularities and help to detect breast cancer early before they can be felt when it is most treatable.
Nowadays Digital mammography takes an electronic image of the breast and stores it directly in a computer. Digital mammography us...

...sue. A_1765_1.RIGHT_MLO has oval shape mass with obscured margin and found as benign in pathology report. Malignant masses are ill-defined due to the presence of infiltrating cancer spread. In architectural distortion outline of the tissue is distorted. It could be lobular invasive carcinoma or benign disease (C_0020_1.RIGHT_CC) due to radial scar following surgery or biopsy.
CONCLUSION:
The proposed multimodel segmentation was tested with almost all combination of mass shapes and margins in CC and MLO views and the segmented abnormal region was verified with ground truth table images in which abnormality marked by radiologist in the DDSM database. Further feature extraction methods and classifier has to be developed for fully automated diagnosis CAD system. Further study has to be carried out to test the algorithm for the segmentation of micro calcifications.
It was a benign tumor that continued to grow for three years to the size of a basketball, weighing approximately 10 pounds.
Over the past decade breast cancer has become one of the most predominant diseases in the United States. Breast cancer starts out as a malignant tumor in the tissues of the breast which is formed from the uncontrolled growth of abnormal breast cells. Breast cancer is the most common cancer in women, but it can also appear in men. (Stephan, 2010)
A breast biopsy is a procedure in which a sample of suspicious breast tissue is removed from your breast. In a stereotactic breast biopsy, an X-ray of the breast (mammogram) is used during the procedure to locate the area of the breast where the tissue sample will be taken from. After the procedure, the tissue that is removed from the breast is examined under a microscope to see if cancerous cells are present. You may need a stereotactic breast biopsy if you have:
Why is this important? Mammograms don’t prevent breast cancer, but they can save lives by finding breast cancer as early as possible (breastcancer.org). It is important to assure the conditions that the person can remain healthy. Screenings for breast cancer helps find cancer early. When it is shown early, it is often treatable. More people will live longer than expected. For instance, mammograms have been shown to reduce the risk of dying from breast cancer by 35% in women over the age of 50. In women between the ages of 40 and 50, the risk reduction appears to be slightly less. (breastcancer.org). Mammograms is an X-ray picture of the breast. It is important to get mammograms once every year. The earlier, the better a person can get rid of the cancerous cells in their body (Levana, 2014).
Of the few people that know what breast cancer is some of them just believe that it is a lump. They do not know that there is a process to breast cancer they do not know that the tumor comes from somewhere and does not magically appear. Breast cancer can happen a few different ways in the breast, but “the most common type of breast cancer is ductal carcinoma” (cancer.gov). This type of breast cancer begins in the lining of the milk ducts. The ducts are the tubes that carry the milk from the lobules to the nipple. Think of them as little veins running from the nipple to a little pouch. Another place that the cancer could start is...

An Advanced Imaging Modality, such as diagnostic mammography, holds the attention of radiographers everywhere. Diagnostic mammography has more benefits than the public realize. The images taken using digital imaging are stored directly on a computer. A diagnostic mammography may similarly offer changes between normal and abnormal tissues that would be more certainly noted because of an enlarged image that was too blurry to see on a screening mammogram. The amount of follow-up exams needed may be fewer. This in turn means that a smaller amount pictures
Technical factors should be adjusted accordingly depending on the neoplasm. Positioning should not be altered for this pathology. It is vital that all required radiographs are acquired to aid in the diagnosis of the pathology.

Effective cancer screening methods are used to detect or identify the presence of a specific cancer before the individual displays any symptoms of cancer. Early detection of a cancer through screening can save the life of a person who may have died without screening detection. Early detection of cancer can also provide a less costly and more effective treatment than if the cancer progresses requiring more advanced or drastic treatment. Screenings tests for the more common cancers such as breast, colon, prostate or cervical can be non-invasive or only slightly invasive. The majority of screening procedures are non-invasive which is more cost effective, patient convenient, and does not require any patient aftercare. Screening tests usually have a recommended age and frequency. As people age there is a higher risk of cancer and more screening is recommended. There are some considerations on whether to screen or not to screen such as; is the cancer common or fatal, are there detectable symptoms, and how reliable are the test results (Bast, 2000).
MRI has become the modality of choice when imaging soft tissue densities and recently, MRI breast scans have become an accessory exam to regular screening mammography. Breast MRI’s are becoming a standard for women with especially high risks of developing breast cancer due to MRI’s ability to superbly image soft tissues with high contrast. Breast MRI’s have several advantages over traditional mammography. Breast MRI’s are more likely to catch abnormal cells in the breast as the scans are usually performed with image enhancing contrast agents which highlights areas of interest (Newstead, 2012). MRI also does not utilize ionizing radiation to produce images which is a great advantage for some patients. Another advantage of breast MRI is superior
Breast Cancer As defined by Majure, breast cancer is an “uncontrolled growth of abnormal breast cells” (Majure: 110). It is also one of the cancers that women fear the most. Not only do women get diagnosed with breast cancer, men do too. However, it isn't as bad, or as common, in men as it is in women, so doctors don’t recommend screening for men.
Reviewing the state of the art techniques for segmentation we see that this method is used extensively in segmentation of regions in med- ical images. Images with low-contrast do not have well de- fined homogeneous regions, performance may be degraded in these scenarios since the method assumes homogeneous in- tensities in the foreground and background. Level-sets being non-parametric, include a regularization term such as penalty on curve/length/surface area or curvature. These regulariza- tion terms do not contain any information about the shape of the region of interest.
Mammography is a very accurate screening tool for women at both average and increased risk; however, like any medical test, it is not perfect. Although the majority of women with an abnormal mammogram do not have cancer, all suspicious lesions that cannot be resolved with additional imaging should be biopsied for a definitive diagnosis. Breast cancer screening for women at average risk includes clinical breast exam and mammography. This screening tool can often detect breast cancer at an early stage, when treatment is more effective and a cure is more likely (cancersupporttexas.org, 2015). Statistics from the Centers for Disease Control shows that lack of mammography screening is the main cause of
Medical tools in the modern day are almost all made with small, programmed computers inside. “Medical imaging is a vast field that deals with the techniques to create images of the human body. Many of the modern methods of scanning and imaging are largely based on computer technology” ("Importance of Computers in Medicine."). We have been able to apply many of the advanced medical imaging techniques, over the years, thanks to developments in computer science. Magnetic quality imaging uses computer software. To obtain high-resolution images, doctors ...
