"The
most important point in my paper is that nuclear medicine breast
studies such as breast-specific gamma imaging (BSGI) and
positron-emission mammography (PEM) carry much higher radiation
doses and risks than mammography. In fact, a woman can get a
lifetime of annual screening mammography starting at age 40,
including 2 views of each breast, at lower or comparable dose
and risk to a single BSGI or PEM exam. This is because BSGI and
PEM involve injected radioisotopes that distribute to all organs
of the body, while mammography uses externally applied
low-energy x-rays that expose only breast tissue. As a result,
BSGI and PEM involve doses and risks that are 20-40 times higher
than a bilateral, 2-view mammography exam" (Comment

The
Roman
physician Aulus Cornelius Celsus (42BC – 37AD)
described breast carcinoma in his manuscript “De Medicina”.
Celsus defined four stages of disease: cacoethes (early stage
and surgically curable tumour), carcinoma without skin
ulceration, carcinoma with ulceration and advanced exophytic
lesion
