Definition of Cancer
Cancer is a disease that occurs due to the growth of abnormal cells that are not controlled, causing normal body tissue damage. Basically, the human body consists of trillions of cells scattered in every organ and part. Later, these cells will continue to grow and develop into new cells. Because it has been replaced, naturally unhealthy, malfunctioning and old cells will die.
While cancer cells will not die by themselves. The cell will multiply to an amount that cannot be controlled anymore. These changes can trigger the appearance of cancer cells. This disease can appear on any part of the body because it comes from cells in the human body. This answers the question why there are so many types of cancer. Based on reports and research, there are more than 200 different types of cancer.
Risk Factors
There are many factors that increase your risk of getting cancer. Among others:
Family history.
Age. Ages over 65 years are more at risk for developing cancer.
Bad habits. Like consuming excessive alcohol, smoking, excessive sun exposure, obesity, and unsafe sex.
Health condition. Some chronic health conditions, such as ulcerative colitis, also increase the risk of certain types of cancer.
Living environment. Hazardous chemicals such as asbestos and benzene at home or work can be factors that increase the risk of this disease.
Causes of Cancer
The main cause of cancer is the occurrence of changes (mutations) in genes in cells. It contains thousands of DNA in genes that instruct cells to carry out their functions in the organs of the body where the cell lives. However, the process is not necessarily always perfect. When cell division occurs, there is a risk that new cells from the division will contain defective genes or multiply too much. This is called a gene mutation, marked by changes in the structure of genes.
Usually, new gene mutations will potentially cause cancer if they occur more than five times and involve different genes. This process can take years until the cells divide and form a large enough cancer cell. Only then the symptoms begin to appear and cancer cells appear when the body is examined. But in children, gene damage has occurred since in the womb or from birth.
In general, there are two cancer-causing factors that most often occur, namely internal factors (such as heredity) and external factors (for example, hormonal changes, obesity , lack of exercise, smoking habits, and exposure to radiation, viruses, and chemicals) .
