Cancer- Much to Know About

More than 500 billion cells in our body are changed daily, however, natural selection has enabled us to develop defenses against cell mutations that might cause cancer. It is this relationship between evolution and the body’s fight against cancer which is explored in a new study.
Cancer is far from a single well-defined disease that can identify and eradicate. It is highly diverse and the theory of evolution allows to consider cancer as a complex ecosystem and evolving. This approach can improve the understanding, treatment and prevention of a number of different cancers.


By applying the principles of evolutionary biology, the new research question: Why do we get sick of cancer, despite the powerful suppression mechanisms of the body against cancer? How evolutionary principles, like natural selection, mutation and genetic drift, working in an ecosystem of cancer? How can we use evolutionary theory to minimize the cancer rate in the world?
Evolutionary medicine allows us to see the explanations of the features that leave bodies vulnerable to disease.
These evolutionary explanations include the role of environmental factors, such as the relationship between the availability of snuff and lung cancer, a co-evolution with a rapid evolution of pathogens, the limitations on what can make the selection; compensation, such as the ability to repair tissues against cancer risks, reproductive success at the expense of health defenses with the costs and benefits, such as inflammation.

Many of the side effects caused by the radiation therapy alone appear in the area concerned. They are caused by disturbances and injuries of cancer cells that divide rapidly. Its effect is temporary and can tratrase, always in consultation with your doctor.

His appearance takes place during the second or third week of continuous treatment, and its duration varies, but can permancer several weeks once the same.

Serious side effects after radiotherapy application are rare. While the most immediate consequence and exposed by a larger number of patients is fatigue, which can vary from mild or moderate stage, to extreme cases.

In each patient may evolve at different rates. The treated area and the combination with other therapies, such as chemotherapy, are factors that affect this disorder.


Find time to care
