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 .

Esophageal cancer is the eighth-most frequently-diagnosed cancer worldwide, [2] and because of its poor prognosis, it is the sixth most-common cause of cancer-related deaths. [55] It caused about 400,000 deaths in 2012, accounting for about 5% of all cancer deaths (about 456,000 new cases were diagnosed, representing about 3% of all cancers).
Radiation-induced cancer. Exposure to ionizing radiation is known to increase the future incidence of cancer, particularly leukemia. The mechanism by which this occurs is well understood, but quantitative models predicting the level of risk remain controversial. The most widely accepted model posits that the incidence of cancers due to ionizing ...
The guidelines give drink amounts in a variety of formats, such as standard drinks, fluid ounces, or milliliters, but have been converted to grams of ethanol for ease of comparison. The daily limits range from 10-30 g per day for men and 10-24 g per day for women. Weekly limits range from 27-252 g/week for men and 27-168 g/week for women.
Under the LCR, if tests show that the level of lead in drinking water is in the area of 15 ppb or higher, it is advisable—especially if there are young children in the home—to replace old pipes, to filter water, or to use bottled water. EPA estimates that more than 40 million U.S. residents use water "that can contain lead in excess of 15 ppb".
The new study added eight more types of cancer to that list: Gastric cardia cancer (a cancer of the stomach lining) Cancer of the small intestine. Estrogen receptor-positive breast cancer. Ovarian ...
