Breast cancer is the fitful growth of cells that originate in the breast tissue. Breast
cancer is any form of malignancy which develops from breast cells. Cancer is a disease in
which malignancy cells in the body grow, change and multiply out of control. It is the most
common cancer disease in women worldwide, especially those who are in the age group of 40
to 55 years and one of the leading causes of death from cancer in women. Breast cancer is
reported as the second most prevalent cause of the cancerous death in the report of World
Health Organization]. Breast cancer is"the second most common cancer worldwide. There
were over 2 million new cases reported in 2018.
The recent statistics of a study by American Cancer Society gives an alarming message
that about 3,30,080 new cases of breast cancer are expected to be diagnosed in women in the U.S.
and about 2,550 new cases of invasive breast cancer are expected to be diagnosed in men in 2018.
These new cases of breast cancer in women are further classified as 2,66,120 new cases of invasive
and 63,960 new cases of non-invasive breast cancer. A man's lifetime risk of breast cancer is about
1 in 1,000 whereas 1 in 8 for women which is about 12.4% chances of having breast cancer over
the course of the lifetime . The worldwide cancer statistics report says breast cancer
is the third most common cancer in the world in terms of number of new cases .
In India, there are around 2.5 million diagnosed with cancer and will lead to 5,56,600
deaths per year. By 2020, India is reported to have over 17.5 lakhs diagnosed patients with
breast cancer and near 8.8 lakhs deaths caused by this disease . As reported in literature,
most prevailing cancer in India is breast cancer and its explanation is a 27% count in all types
of cancer in women.
Early detection is an exhausting effort and a nerve center on cancer detection. Imaging modalities and
advancements in technology disported a far-reaching role in early detection [4]. Mammography
has been extensively recognized as a diagnostic and shielding weapon for an early detection of
breast cancer and even up to ten years before detection and diagnosis stage. Mammography can
curtail the number of mortality native to breast cancer, particularly among women in an age group
of years 40-70. Mammography implies the assimilation of anomalies such as calcifications and masses to detect breast cancer. It makes image analysis as a thrust area of research for an early detection of breast cancer.
The enactment of a Computer Aided Diagnosis (CAD) system can revamp the early cancer
detection rate and could also share the experts workload [6]. A recent report manifested that the
enactment of CAD refined the process of breast cancer detection by 7.62% and this automated or
semi-automated gizmo has captivated great considerations [6]. Many Computer Aided Diagnosis
systems prospected to assist radiologists to curtail the diagnostic errors effectively by using
mammogram and MRI imaging modality of breast mass or calcification [33] [26]. Computer
Aided Diagnosis systems substantiated a probably compelling tool for detecting the masses or
micro calcifications in recent considerations
