Probenecid, also sold under the brand name Probalan, is a medication that increases uric acid excretion in the urine. It is primarily used in treating gout and hyperuricemia . Probenecid was developed as an alternative to caronamide [ 1 ] to competitively inhibit renal excretion of some drugs, thereby increasing their plasma concentration and ...
Cancer slope factors (CSF) are used to estimate the risk of cancer associated with exposure to a carcinogenic or potentially carcinogenic substance. A slope factor is an upper bound, approximating a 95% confidence limit , on the increased cancer risk from a lifetime exposure to an agent by ingestion or inhalation .
As with most blood tests, false-negatives can happen, meaning results could come back negative when a cancer does exist — although Grail reports that negative cancer test results from Galleri ...
The objective of cancer screening is to detect cancer before symptoms appear, involving various methods such as blood tests, urine tests, DNA tests, and medical imaging. [ 1 ] [ 2 ] The purpose of screening is early cancer detection, to make the cancer easier to treat and extending life expectancy. [ 3 ]
Reference ranges (reference intervals) for blood tests are sets of values used by a health professional to interpret a set of medical test results from blood samples. Reference ranges for blood tests are studied within the field of clinical chemistry (also known as "clinical biochemistry", "chemical pathology" or "pure blood chemistry"), the ...
For individual women, the discriminatory accuracy [5] for colon cancer was 0.67, for ovarian cancer 0.59, and for pancreatic cancer was 0.71. For individual men, the discriminatory accuracy [5] for colon cancer was 0.71 and for pancreatic cancer was 0.72. These values exceed the performance of many other cancer risk prediction tools.

For example, the incidence of breast cancer in a woman in the United Kingdom at age 55 to 59 is estimated at 280 cases per 100.000 per year, [6] and the risk factor of having been exposed to high-dose ionizing radiation to the chest (for example, as treatments for other cancers) confers a relative risk of breast cancer between 2.1 and 4.0, [7 ...
Prostate cancer imaging developed by university researchers has shown “extremely encouraging” results in its first clinical trials. A team at Heriot-Watt University, Edinburgh, leading the ...
