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 side effects of bicalutamide, a nonsteroidal antiandrogen (NSAA), including its frequent and rare side effects, have been well-studied and characterized. The most common side effects of bicalutamide monotherapy in men include breast tenderness , breast growth , feminization , demasculinization , and hot flashes .
[6] At the turn of the century, she led a study finding that "women with mutations of the BRCA 1 or 2 gene who had breast-conserving surgery after cancer diagnosis may get the same benefit from radiation therapy with no greater incidence of short- or long-term side effects as women with non-hereditary cancer."
Breast cancer is not a single disease but multiple ones, each carrying varying degrees of risk for endangering women’s health. In recent years, many researchers have been focused on DCIS: ductal ...

A study of radiation risk from mammography concluded that for women 40 years of age and older, the risk of radiation-induced breast cancer was minuscule, particularly compared with the potential benefit of mammographic screening, with a benefit-to-risk ratio of 48.5 lives saved for each life lost due to radiation exposure.

White dwarfs with hydrogen-poor atmospheres, such as WD J2147–4035, are less affected by CIA and therefore have a yellow to orange color. [80] [77] The white dwarf cooling sequence seen by ESA's Gaia mission. White dwarf core material is a completely ionized plasma – a mixture of nuclei and electrons – that is
Staging breast cancer is the initial step to help physicians determine the most appropriate course of treatment. As of 2016, guidelines incorporated biologic factors, such as tumor grade, cellular proliferation rate, estrogen and progesterone receptor expression, human epidermal growth factor 2 (HER2) expression, and gene expression profiling into the staging system.
