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 ...
Health threats from cosmic rays are the dangers posed by cosmic rays to astronauts on interplanetary missions or any missions that venture through the Van-Allen Belts or outside the Earth's magnetosphere. [1] [2] They are one of the greatest barriers standing in the way of plans for interplanetary travel by crewed spacecraft, [3] [4] [5] but ...
Radiation hormesis. 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). Radiation hormesis is the hypothesis that low doses of ionizing radiation (within the region of and just above ...
Move more. Not exercising accounts for about 3% of cancer cases, according to the new research. Conversely, incorporating physical activity into your daily routine can reduce cancer risks by as ...
Wear sunscreen. It may seem obvious, but sun protection is one of the easiest things you can do to dramatically reduce your risk for skin cancer, the experts say. "It is super important to use ...

People with a "cancer personality"—depressed, repressed, self-loathing and afraid to express their emotions—were believed to have manifested cancer through subconscious ...
