Fungal infections can also emerge in those that fail antimicrobial therapy and stay febrile for over 7–10 days. Exogenous infections can be caused by organisms that colonize the skin such as Staphylococcus aureus or Streptococcus spp. and organisms that are acquired from the environment such as Pseudomonas spp.
Radiation hormesis is the conjecture that a low level of ionizing radiation (i.e., near the level of Earth's natural background radiation) helps "immunize" cells against DNA damage from other causes (such as free radicals or larger doses of ionizing radiation), and decreases the risk of cancer. The theory proposes that such low levels activate ...
The oxygen effect has particular importance in external beam radiation therapy where the killing of tumour cells with photon and electron beams in well oxygenated regions can be up to three times greater than in a poorly vasculated portion of the tumour.
Eating more fish was associated with a higher risk of melanoma in a new study. What seafood lovers need to know. Fish and Skin Cancer: Seafood Associated With Higher Melanoma Risk
A 2018 journal article studying the cancer called it "exceptionally deadly," and said those who are diagnosed have a life expectancy of just 10 months. ... the ODNR also noted that 3,500 fish were ...
Ionizing radiation is generally harmful and potentially lethal to living things but can have health benefits in radiation therapy for the treatment of cancer and thyrotoxicosis. Its most common impact is the induction of cancer with a latent period of years or decades after exposure.
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 dermatitis, in the form of intense erythema and vesiculation of the skin, may be observed in radiation ports. [3]: 131 As many as 95% of patients treated with radiation therapy for cancer will experience a skin reaction. Some reactions are immediate, while others may be later (e.g., months after treatment).
