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 causes listed are relatively immediate medical causes, but the ultimate cause of death might be described differently. For example, tobacco smoking often causes lung disease or cancer, and alcohol use disorder can cause liver failure or a motor vehicle accident. For statistics on preventable ultimate causes, see preventable causes of death.
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 ...
Constitutional Symptoms. Unexplained weight loss: Weight loss that is unintended and not explained by diet, exercise or other illness may be a warning sign of many types of cancer. Unexplained pain: Pain that persists, has no clear cause, and does not respond to treatment may be a warning sign of many types of cancers.
Acute radiation syndrome ( ARS ), also known as radiation sickness or radiation poisoning, is a collection of health effects that are caused by being exposed to high amounts of ionizing radiation in a short period of time. [1] Symptoms can start within an hour of exposure, and can last for several months.
Radiation damage is the effect of ionizing radiation on physical objects including non-living structural materials. It can be either detrimental or beneficial for materials. Radiobiology is the study of the action of ionizing radiation on living things, including the health effects of radiation in humans.
Tobacco smoke, for example, causes 90% of lung cancer. Tobacco use can cause cancer throughout the body including in the mouth and throat, larynx, esophagus, stomach, bladder, kidney, cervix, colon/rectum, liver and pancreas. Tobacco smoke contains over fifty known carcinogens, including nitrosamines and polycyclic aromatic hydrocarbons.
HPV disease is the leading cause of cervical cancer, therefore making the HPV vaccine the primary prevention measure for the cancer. Screening with the Papanicolaou (Pap) test is consequently the second measure of prevention. The test identifies cells that are precancerous, and are often credited for the reduced mortalty.
