The cancer has a 18-38% rate of metastasis. 40% occur on the lower limb and the malignant change is usually painless. This malignant change of the wound happens a long time after initial trauma, usually 10–25 years later. Its edge is everted and not always raised.
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 ...
A 0.05 Gy dose will increase death due to cancer 10 fold, from the normal 0.5 per 1000 birth rate to a rate of 5 per 1,000. [ citation needed ] An antenatal dose of 1 Gy in the first trimester causes the lifetime risk of fatal cancer sometime in the child's life to increase from c. 25% in non-exposed humans to 100% in the first trimester after ...
Stab wounds occur four times more than gunshot wounds in the United Kingdom, but the mortality rate associated with stabbing has ranged from 0-4% as 85% of injuries sustained from stab wounds only affect subcutaneous tissue. In Belgium, most assaults resulting in a stab wound occur to and by men and persons of ethnic minorities.
Atypical teratoid rhabdoid tumor. An atypical teratoid rhabdoid tumor ( AT/RT) is a rare tumor usually diagnosed in childhood. Although usually a brain tumor, AT/RT can occur anywhere in the central nervous system (CNS), including the spinal cord. About 60% will be in the posterior cranial fossa (particularly the cerebellum ).
Dose fractionation. Dose fractionation effects are utilised in the treatment of cancer with radiation therapy. When the total dose of radiation is divided into several, smaller doses over a period of several days, there are fewer toxic effects on healthy cells. This maximizes the effect of radiation on cancer and minimizes the negative side ...
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.
Traumatic cardiac arrest ( TCA) is a condition in which the heart has ceased to beat due to blunt or penetrating trauma, such as a stab wound to the thoracic area. [1] It is a medical emergency which will always result in death without prompt advanced medical care. Even with prompt medical intervention, survival without neurological ...
