Doctors may use a variety of laboratory tests if cancer is suspected. In conducting lab tests for cancer, samples of blood, urine, other bodily fluids or tissue are examined for abnormal cells or tumor markers that may determine whether a person has the disease or a precancerous condition. Lab tests also may be used to screen high-risk patients, pinpoint the stage of cancer, identify treatment options and evaluate whether the cancer is responding to treatment. Lab tests may also be used to determine whether a patient has a cancer recurrence—a disease that has returned to its original location—or whether a new cancer has developed. This diagnostic test helps capture, identify and count circulating tumor cells in a blood sample. CTCs are cancer cells that detach from solid tumors and enter the bloodstream.
AI detects breast cancer as accurately as expert radiologists, study finds

Metrics details. Breast cancer survivors are at risk for contralateral breast cancer CBC , with the consequent burden of further treatment and potentially less favorable prognosis. We aimed to develop and validate a CBC risk prediction model and evaluate its applicability for clinical decision-making. We included data of , invasive non-metastatic breast cancer patients from 20 studies with CBC events and a median follow-up of 8.
A Google artificial intelligence system proved as good as expert radiologists at detecting which women had breast cancer based on screening mammograms and showed promise at reducing errors, researchers in the United States and Britain reported. The study, published in the journal Nature on Wednesday, is the latest to show that artificial intelligence AI has the potential to improve the accuracy of screening for breast cancer, which affects one in eight women globally. The findings of the study, developed with Alphabet Inc. The team, which included researchers at Imperial College London and Britain's National Health Service, trained the system to identify breast cancers on tens of thousands of mammograms.
For women, breast cancer is the most common cancer and the second-leading cause of cancer deaths. That's according to the Canadian Cancer Society. Better treatments mean longer survival, Overall, if discovered early, more than 90 per cent of women will survive at least five years following a diagnosis of breast cancer.
