What is cancer? Is its frequency increasing?
Cancer is a terrorist movement initiated by the slowing down of the death of the cells in the tissues that make up our organs, by one of these cells, which multiply and function regularly and in communication with each other, by changing their character and terminating their relationship with normal tissues and cells. Our body is prepared for this terrorist event and has many protective mechanisms. However, the information we have obtained today shows that in some cases, weaknesses in these mechanisms may occur in our body, and that cells that undergo carcinogenic changes, taking advantage of these, can escape these protection mechanisms and proliferate and cause cancer. Again, our current knowledge shows that most, if not all, cancer cells are born carrying the genetic code that may one day turn into cancer. In other words, the time and manner in which many cancers occur in our body are genetically determined at birth or even before birth.
So what can we change?
We cannot change our genetics, our parents, our grandparents, our great-grandparents' grandparents, our past hundreds of thousands of years ago. However, this does not mean that we cannot completely change the risk of getting cancer.
We can summarize it as follows: If you use a truck carrying dangerous goods carefully and cautiously, you can travel safely. If fire and explosives come together, the formation of cancer is triggered at that moment. Even though a person who has never smoked throughout his life and does not allow smoking around him is genetically predisposed to cancer, this predisposition will not pose a major threat.
According to WHO (World Health Organization)data, the world Approximately 14 million new cancers occur every year, approximately 1% of which are children. Every year, approximately 8 million people in the world die due to cancer. The number of children who die due to cancer every year is approximately 100,000.
Cancer is increasing. M.O. As far as we understand from studies conducted on human bones dating back 5 million years, cancer has been threatening human health since then. . We also see from books written in the 18th and 19th centuries that cancer was increasing rapidly and causing deaths in those days. Cancer increases as the population and life expectancy increases.
When the trends and annual increases all over the world are reflected in the following years, the total number of people diagnosed with cancer was 14.1 million in 2012, and it is predicted that this number will be 20 million in 2025. There is no such a large increase in childhood cancers, the total increase has been 20% in the last 50 years.
These data show us that childhood cancers are due to more immutable causes such as genetics, whereas adult cancers are caused by more permanent causes such as genetics. It suggests that age cancers are more related to environmental effects, lifestyle and age.
