of health care services; a false-positive recall causes an influx in visits to the outpatient clinic the first year after screening. The quality of life is lowered as some women may have altered health behavior and trust in the health care system. The timing for false-positive corrections is time forming. After six months, it is statistically noted that only 64% were recanted to be cancer- free; and after one year about 90% cancer-free, and only after two years were also declared cancer-free (Tabár et al., 2001). False-negative tests There are many moments where cancers are not detected after a normal screening and are found before the next scheduled mammogram. Abnormalities that were either overlooked at the last mammogram or are rapidly growing cancers that become obvious within that time frame account for 65 percent of interval cancers. The use of digital mammography is increasing,
and detection rates of ductal carcinoma in situ (DCIS) and invasive cancers are higher (Tabár et al., 2001). The use of digital mammography versus screen-film mammography may overall reduce the rate of missed interval cancers. In hindsight, there would be a possible increase in the amount of over-diagnosis with the increase in detection rates with digital mammography. Also, sadly, not all women diagnosed with interval cancer would benefit from early detection or digital mammography. Psychologically, having a falsely interpret reading by their last normal mammogram could possibly delay seeking medical care. Tabár et al. (2001) state, for every 1,000 women invited to mammography screening every second year for 20 years from age 50, 200 will experience a false-positive mammogram, 30 will undergo a biopsy due to a false- positive mammogram, and three will be diagnosed with interval cancer. Positive Predictive Value of Mammography Women are participating at high levels for routine screening mammography for early detection and improvements in treatment. Despite women being educated on the importance of screening, the wide variability in the reported accuracy of mammography and biopsy among radiologists is still concerning. The concerns gained efforts across the nation with the
