As one of the top five most deadly killers in the planet, tumor has been examined by so a lot of medical experts. So far, they still haven’t found the wonderful healing method for the tumor patients. But even so, they have managed to invent a few techniques to postpone or at least to slow down the development of the tumor cells. Some other experiences were mainly conducted to obtain the causes of the cancers. There are so many things that have been suspected as the causes of the cancer sickness. But somehow, the experts still haven’t been able to clearly mention the causes of the cancer illness. So far, they still couldn’t define what the main cause of the cancer sickness is. They have mentioned several things that have been categorized as the causes of the cancer disease. Those causes are divided into three categories.
The first categories are the agent and events. The agents such as viruses and the events such as genetic mutations may trigger some genetic modifications that might trigger the tumor cells. The second category is the accurate nature of the genetic damage, and the last one is the consequences of the genetic damage. Here are some explanations of the suspected causes of the cancer illness. The first is the mutation. The cancer cell has the ability to impact the cell growth and metastasis. The substances that triggered the DNA mutations are called as the mutagens, the mutagens are carcinogens. Some contents inside the tobacco have been claimed as the excellent triggers for the mutagens. The experiments on some lung tumor patients indicated the strong correlation between tumor and the smoking habits. The exposure of the ionizing radiation also has been claimed as the cause of the cancer disease as well.
The other suspected causes of the cancer illness are the bacteria and the virus infection. There are some researchs that claimed the infection of the pathogen bacteria causes the cancers. Some other experiments’ results also indicate that some cancer cases were triggered by the viral infection. The imbalances of the hormonal system in human’s body could also trigger the cancer. At least, according to some researchs results, it shows some significant effect of the hormonal imbalances. The dysfunction of the immune system could also trigger the tumor. It means, some people with the AIDS have the biggest possibilities to have the tumor illness as well. The other causes of the tumor would be; heredity, receiving organ donors that might have been exposed by the cancer cells, and many other causes. The life style also has been claimed as one of the cause of the tumor sickness. Some alcohol, drugs, and junk food also have been claimed as the wonderful factors to support the developments of the cancer cells.
