A cancer cluster is a disease cluster in which a high number of cancer cases occurs in a group of people in a particular geographic area over a limited period of time. [ 1 ] Historical examples of work-related cancer clusters are well documented in the medical literature.
If all cancer patients survived and cancer occurred randomly, the normal lifetime odds of developing a second primary cancer (not the first cancer spreading to a new site) would be one in nine. [29] However, cancer survivors have an increased risk of developing a second primary cancer, and the odds in 2003 were about one in 4.5. [29]
A cancer syndrome or family cancer syndrome is a genetic disorder in which inherited genetic mutations in one or more genes predisposes the affected individuals to the development of cancers and may also cause the early onset of these cancers. Although cancer syndromes exhibit an increased risk of cancer, the risk varies.
Hereditary nonpolyposis colorectal cancer (HNPCC) is a hereditary predisposition to colon cancer.. HNPCC includes (and was once synonymous with) [1] Lynch syndrome, an autosomal dominant genetic condition that is associated with a high risk of colon cancer, endometrial cancer (second most common), ovary, stomach, small intestine, hepatobiliary tract, upper urinary tract, brain, and skin.

Estimates place the worldwide risk of cancers from infectious causes at 16.1%. [1] Viral infections are risk factors for cervical cancer, 80% of liver cancers, and 15–20% of the other cancers. [2] This proportion varies in different regions of the world from a high of 32.7% in Sub-Saharan Africa to 3.3% in Australia and New Zealand. [1]
The instrument closely resembles survey items and topics found on HINTS 5, Cycle 4 (2020), and includes other topics relevant to cancer survivors. A unique aspect of the dataset is that key data elements from the cancer registry datasets are linked to the survey responses, providing a more in-depth view of each respondent's cancer diagnosis.
A new federal report shows that one drink per day could raise the risk of liver damage and several cancers. The report follows a recommendation by the U.S. Surgeon General on safe alcohol ...
Alternative assumptions for the extrapolation of the cancer risk vs. radiation dose to low-dose levels, given a known risk at a high dose: supra-linearity (A), linear (B), linear-quadratic (C) and hormesis (D). The linear dose-response model suggests that any increase in dose, no matter how small, results in an incremental increase in risk.
