Cancer
Cancer is defined as a serious and chronic disease. Its cells are hostile and destructive. It is characterized by its ability to invade and control body tissues, or to move from place to place in the body, whether it is distant or near. It can also be defined as the spread and growth of cancer cells In the body can not be controlled or controlled, it is noteworthy that it affects different parts of the body.
Symptoms of cancer
Symptoms and signs of cancer vary according to the member or place of injury within the body, but it should be noted that there are some signs and general symptoms that are usually associated with it, including:
- Feel tired and tired.
- Heat or high body temperature.
- Feeling pain in the body.
- Feeling of subcutaneous tumors.
- Significant weight changes, either increase or decrease without obvious reasons for it.
- Difficulty swallowing.
- Indigestion continuously, in addition to the lack of a sense of comfort after eating.
- Chronic cough.
- Disorders in urination and ejaculation.
- The incidence of skin disorders, which is: redness or stenosis, or yellowing, and the presence of skin ulcers difficult to heal.
- A change in the form of birth defects in humans.
- Bleeding and sound disturbances.
Types of cancerous tumors
Benign tumor
It is a tumor that grows mainly in a specific area of the body. Perhaps the most prominent characteristic is that it can not control and invade neighboring cells. It also has the advantage of not moving from one part of the body to another, but in rare cases it can turn into a malignant tumor. The inability of this tumor to move from one part to another is that it is covered with fibrous tissue and enveloped in it, and is usually removed by removal or surgery, and after removal from the body is not returned to him at all.
Malignant tumor
It is a tumor that travels quickly in the body, and does not allow the damaged and damaged cells to compensate, which makes them proliferate abnormally without interruption, which contributes to the disruption of the function of the place or the affected member, it is characterized as moving from one part to another within the body, mediated by the blood and lymphatic system .
Risk of cancer
Age
Cancer may take years and decades to appear and develop, so it is not diagnosed in most people until they reach the age of 55 years or more. Over time, cancer tumors are discovered. Their cells range from 100 million cells to 1 billion cells. The original cell began to grow before the disease was discovered five years or more, and it should be noted that although the disease is widespread in adults, it can be said that it is not only in this age group, but may affect people of different ages .
Habits
Some lifestyles and human behavior contribute to their increased risk of drinking alcohol, smoking, excessive sun exposure, frequent sunburn, and unsafe sex.
The genetic history of the family
The genetic infection rate is almost 10 percent. If the disease is widespread in a person’s family, genetic mutations are likely to be passed on from generation to generation. Many doctors recommend regular physical examinations to determine the susceptibility of the person But genetic mutagenesis does not necessarily mean cancer.
Human health status
Some chronic health disorders contribute to the increased risk of cancer. The most prominent of these disorders is ulcerative colitis.
The surrounding environment
If a person lives in an environment full of chemical harmful substances, it plays a large role in increasing the likelihood of infection.
