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 ...
Many of the 55 responders who died from cancer had cancer before September 11, 2001, but most of the cancer patients developed the disease afterward. The 98 deaths up to 2008 included: 55 cancers; 21 traumatic injuries (motor-vehicle crashes, gunshots and five homicides, including four cops killed in the line of duty)
Exposing skin to the ultraviolet radiation in sunlight has both positive and negative health effects. On the positive side, exposure allows for the synthesis of vitamin D 3. Vitamin D has been suggested as having a wide range of positive health effects, which include strengthening bones [1] and possibly inhibiting the growth of some cancers.
Smoking is the leading cause of lung cancer, but not all people who get lung cancer are smokers. In fact, 10% to 20% of people who get lung cancer have never smoked, according to the U.S. Centers ...
One study found that people who consume about 5 ounces of processed meat (or less than two hot dogs) weekly have a 46% greater risk of heart disease and a 50% increased risk of mortality compared ...
In the United States, the American Cancer Society reported that the demographics of cancer patients are increasingly shifting from older individuals to middle-aged people. While adults older than ...
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 ...
From model-based epidemiological studies, the incidence of thyroid cancer cases due to the accident by 2065 compared with other cancer-inducing sources (diet etc.) across Europe, is roughly 1 in 10,000 as a probable worst-case scenario. Thyroid cancer is relatively amenable to treatment for several decades. Attributing a 1% mortality rate by ...
