Because, daily exercise maintains body metabolism in a steady way and this prevents altered metabolism within our body. Also, proper sleep which should be at least 6 hours at night can reduces the altered endocrine and metabolic functions. So, proper sleep is very important. This all can reduce cancer risks upto 55%.
Natural killer cell From Wikipedia, the free encyclopedia (Redirected from Natural Killer cell ) Jump to: navigation , search Natural killer cells (or NK cells ) are a type of cytotoxic lymphocyte critical to the innate immune system . The role NK cells play is analogous to that of cytotoxic T cells in the vertebrate adaptive immune response . NK cells provide rapid responses to virally infected cells and respond to tumor formation, acting at around 3 days after infection . Typically immune cells detect MHC presented on infected cell surfaces, triggering cytokine release causing lysis or apoptosis . NK cells are unique, however, as they have the ability to recognize stressed cells in the absence of antibodies and MHC, allowing for a much faster immune reaction. They were named “natural killers” because of the initial notion that they do not require activation in order...
