What is the initiation of a tumor?
Tumor initiation is the initial process of cell changes that results in cancer formation and usually concern cancer. These changes are related to the exposure of carcinogenic substances that change DNA and other structure of certain cells, and as soon as changes, they are not reversible. The tumor initiation process leaves cells vulnerable to future carcinogens and these subsequent exposures usually cause cancer cell growth.
It is known that many substances act as mutagens, which are substances that interact with cellular deoxyribonucleic acid (DNA) and can cause changes in cellular structure. About 70% of these act as tumor initiators and begin cell changes that can eventually lead to cancer development. Another 30% will not start the initiation of the tumor, but enzymes metabolizing drugs in the body may turn a non -criminal mutagenic compound that can eventually cause cancer, resulting in effect.
those mutagens that cause the tumor to start are considered carcinogenic in that they significantly contribute to cancer growth. In many cases, however, the initiators must be followed by a tumor promoter, a substance that transforms already damaged cells into tumors. Promotors can be a completely different type of mutagen, or they may be the same that caused the tumor to start. If one substance and a promoter are initiator, it is referred to as complete carcinogen because it can cause cancer without other substances.
cancer during the initiation phase is rarely identified because it does not cause any tumors or system problems at this point. Once the tumors begin to grow, it can be found, but the point at which it is discovered will vary. Normally it depends on the size and location of the tumors and on any effect of cancer caused in the body.
people who are worried about mutagens and subsequent tumor initiation can still take certain steps to protect. First, minimizing exposure to knownIn many cases, carcinogens may prevent the initiation and progression of the tumor. Regular use of protective equipment such as respiratory masks, gloves and clothing of people who run on such a substance.
According to a report from the British Research Center for British Columbia Cancer, it can also eat low -concrete carbohydrate foods to help reduce or prevent tumor from starting. According to the results published in July 2011, mice that were exposed to carcinogens, but ate low carbohydrate food, significantly less tumor growth than those in the control group. It is important to note that this diet was also relatively low in fat, as research has shown that fat can promote tumor growth.
