A BI-RADS classification of 4 or 5 warrants biopsy to further evaluate the offending lesion. [3] Some experts believe that the single BI-RADS 4 classification does not adequately communicate the risk of cancer to doctors and recommend a subclassification scheme: [4] 4A: low suspicion of malignancy, about > 2% to ≤ 10% likelihood of malignancy
The underlying purpose of staging is to describe the extent or severity of an individual's cancer, and to bring together cancers that have similar prognosis and treatment.

[4] At risk women should consider getting a scan when their risk is equal to that of a normal 65-year-old woman.
The TI-RADS (Thyroid Imaging Reporting and Data Systems) are sonographic classification systems which describe the suspicious findings of thyroid nodules. [12] It was first proposed by Horvath et al., [13] based on the BI-RADS (Breast Imaging Reporting and Data System) concept. Several systems were subsequently proposed and adopted by ...

On January 17, 1987, a patient was to receive a treatment with two film-verification exposures of 4 and 3 rads, plus a 79-rad photon treatment for a total exposure of 86 rads. Film was placed under the patient and 4 rads were administered through a 22 cm × 18 cm opening.
A person’s immune system is able to fight off many diseases, but it tends to be ineffective against cancer because of a mechanism called immune tolerance. Scientists find dangerous parasite that ...
The baseline predicted cancer incidence or number of new cancers is about to 7,000. [ 6 ] 850 of these cancers were diagnosed in individuals with estimated doses greater than 0.005 Gy. [ 6 ] In other words, they were due to the atomic bomb radiation exposure, which is 11% or 1 in 10 of the cancers diagnosed. [ 7 ]
