    Toxins are highly reactive and unstable molecules which are produced in one’s body naturally as being a byproduct of metabolism (oxidation), or by contact with toxins within the environment such as cigarette and ultraviolet light. Free-radicals possess a lifespan of only a part of a second, but in that time can damage DNA, sometimes inducing the mutations that can lead to cancer. Antioxidants in the foods we eat can neutralize the unstable molecules, reducing the chance of damage.

    We are going to look at the structure, causes, and outcomes of toxins, as well as what you should learn about antioxidant supplements when you have cancer.

    Definition and Structure of Free-radicals

    Toxins are atoms that have an unpaired electron. Due to this lack of a reliable variety of housing electrons, they’re in a constant search to bind with another electron to stabilize themselves-a procedure that could cause injury to DNA and also other parts of human cells. This damage be the cause from the development of cancer as well as other diseases and accelerate the aging process.

    Kinds of Free-radicals

    There are lots of forms of free-radicals, though, in humans, the most significant are oxygen free radicals (reactive oxygen species). Examples include singlet oxygen (when oxygen is "split" into single atoms with unpaired electrons), baking soda, superoxides, and hydroxyl anions.

    Causes/Sources of Toxins

    You might wonder where free-radicals result from to start with. Toxins can be done in certain various ways. They may be generated from normal metabolic processes in your body, or by experience carcinogens (positivelly dangerous substances) in the environment.

    Free-radicals can be produced both by carcinogens and also the normal metabolic processes of cells.

    Toxins As a result of Normal Metabolic Processes

    Our body often produces poisons while breaking down nutrients to produce the vitality which allows your body to perform. The creation of free radicals in normal metabolic processes similar to this is amongst the reasons the likelihood of cancer increases with age, regardless if everyone has few exposures to cancer-causing substances.

    Poisons On account of Exposure to Carcinogens

    Exposure to carcinogens in our environment also can produce free-radicals. Examples of some carcinogens include:

    Cigarettes

    Ultraviolet radiation

    Radon in the house

    Environmental and occupational substances and chemicals for example asbestos and vinyl chloride

    Some viruses

    Medical radiation

    Polluting of the environment

    How Poisons Can Cause Cancer

    Damage done to genes in the DNA could lead to genes that leave ineffective proteins; proteins must be watchkeepers in the cells from the body. Some mutations may involve genes known as tumor suppressor genes. These genes code for proteins that function to fix damages in DNA or cause cells which can be damaged beyond salvage to get removed by having a procedure for apoptosis (programmed cell death).

    Oncogenes are genes that code for proteins that promote the increase of cells. Normal genes in your body called "protooncogenes" are crucial in advertising the growth of a baby during pregnancy and transiently produce proteins that help with tissue repair. Mutations in these genes (which can be then oncogenes) make continuous production of proteins that promote the development of your cell.

    Most often, it’s a compilation of mutations both in tumor suppressor genes and oncogenes which leads to cancer. Damage (mutations) to tumor suppressor genes allows a damaged cell to live unrepaired (abnormal) and damaged oncogenes promote the expansion of the damaged cell. The effect is-the formation of your cancer cell.
