Question

A new medical imaging device is designed and made for screening of breast cancer. Describe how experiments can be performed and used to determine the accuracy, sensitivity and specificity of the device. Using your own hypothetical values, calculate the accuracy, sensitivity and specificity of the device. Is the device suitable for screening for breast cancer, based on your calculated values of its accuracy, sensitivity and specificity? Explain.

Answer 1

the breast cancer screening means checking a woman's breasts for cancer before there are signs or symptoms of the disease. it can help to find the breast cancer early, when it is easier to treat.

a mammogram is an x-ray of the breast. mammograms are the best way to find breast cancer early, when it is easier to treat and before it is big enough to feel or cause symptoms. at this time, a mammogram is the best way to find breast cancer for most women.

digital mammography provides a good quality image with reduced radiation dose and can detect breast carcinoma in its earlier stages, resulting in good prognosis and improved patient survival.

both screen film mammography and digital mammography use x rays to obtain images. with screen film mammography, the image is captured on film; with digital mammography, the image is captured digitally. digital mammography is developed to address the limitations of film mammography and separates image aquisition and display allowing the optimization of both.
