The anomaly scan, also sometimes called the anatomy scan, 20-week ultrasound, or level 2 ultrasound, evaluates anatomic structures of the fetus, placenta, and maternal pelvic organs. This scan is an important and common component of routine prenatal care . [ 1 ]
However, magnetic resonance imaging (MRI) scans are not associated with a radiation risk, and MRI scans are being evaluated for their use in cancer screening. [51] There is a significant risk of detecting incidentalomas - benign lesions that might be misinterpreted as cancer and put patients at potential risk by undergoing unnecessary follow-up ...
A patient who received a 1:330 risk score, while technically low-risk (since the cutoff for high-risk is commonly quoted as 1:270), might be more likely to still opt for a confirmatory invasive test. On the other hand, a patient who receives a 1:1000 risk score is more likely to feel assuaged that her pregnancy is normal.
Screening targeted towards women with above-average risk produces more benefit than screening of women at average or low risk for breast cancer. A 2013 Cochrane review estimated that mammography in women between 50 and 75 years old results in a relative decreased risk of death from breast cancer of 15% and an absolute risk reduction of 0.05%.

A terminally ill woman whose cancer was missed twice by clinicians is calling for a change in the way radiologists assess scans to prevent more patients having a similar experience.
Obstetric sonography is useful in the assessment of the cervix in women at risk for premature birth. A short cervix preterm is associated with a higher risk for premature delivery: At 24 weeks' gestation, a cervix length of less than 25 mm defines a risk group for spontaneous preterm birth. Further, the shorter the cervix, the greater the risk ...
This is a syndrome that predisposes people to cancer and increases the risk of developing cancer in many different tissues, but particularly in the endometrium, thyroid, and breast. It is inherited autosomally dominantly, with a germ-line mutation of the PTEN tumor suppressor gene present in about 80% of patients.
For example, in the cases of breast cancer and prostate cancer, doctors routinely can identify that the cancer is early and that it has low risk of metastasis. [2] In such cases, medical specialty professional organizations recommend against the use of PET scans , CT scans , or bone scans because research shows that the risk of getting such ...
