As cells become abnormal , damaged or old blood cells survive . Cancer cells are different from normal blood cells in many ways. Cancer cells become invasive and grow out of control. Moreover. Cancer cells can ignore the signals that normally tell blood cells to stop.
Causes Of Cancer Disease:
Cancer starts from the transformation of normal blood cells to tumor cells in multi- process. They are usually progress; Start from cancer disorders malignant tumors. These amendments are the result of communication between human genetic factors and categories of external factors, including:
1-Genetic Factors:
Genes consist of DNA segments. They locate on the chromosomes, which are able to mutate with time and become cancerous. These DNA mutations can result from a many causes, which including lifestyle and choices, and exposure to a certain environmental factors. Moreover, only 6 to 10% of all types of cancers inherit genetically, although these types of Cancers are tend to appear earlier in life.
2-Environmental Factors:
There are many environmental factors can cause Cancer Disease. Essive sun exposure, ionizing radiation traviolet, for instance.
3- High-dose Chemotherapy:
- Exposure to radiation
- Radioactive materials
- Tobacco smoke.
4- Biological Factors:
Such as infections from certain bacteria, viruses, or parasites, Human papillomavirus (HPV), Epstein-Barr virus (EBV), Hepatitis B (HBV) and hepatitis C (HCV) viruses, Kaposi's sarcoma- associated herpes virus (KSHV), Human T- lymphotropic virus, Helicobacter pylori and Merkel cell polyomavirus.
Cancer can start almost anywhere in the human body, which is made up of trillions of cells. Normally, human cells grow and multiply (through a process called cell division) to form new cells as the body needs them. When cells grow old or become damaged, they die, and new cells take their place.
Rare causes of cancer disease :
- Maternal-fetal Transmission:
In many pregnant women. The Trans placental transmission of lymphoma, acute leukemia, carcinoma, and melanoma from mother to her fetus has been observed.
- Organ Transplantation:
The improvement of the donor-derived tumors from organ transplants is very rare. The specific cause of organ transplant associated mors occur after organ transplantation. That causing tumorous. As a result of outgrowth of virus-infected donor cells.
What Are The behavior Factors Can Lead To Cancer Disease?
There are a variety of behavioral factors that can cause genetic mutations, to the development of the Cancer:
- Excessive exposure to ultraviolet light.
- Smoking or use Tobacco.
- Unsafe sex (causes viral infection).
- Contaminated diet.
Inflammatory conditions, such as obesity, ulcerative colitis Materials: Some materials cause cancer through their physical effect on cells, rather than chemical, such as: asbestos, arsenic, Beryllium, Benzene, Chromium, Cadmium, Ethylene oxide, Plutonium.
Risk Factors Lead To Develop Cancer :
There are many different risk factors associated with Cancer. It is usually estimated that by changing the risk factors for the Cancer, which people can affect with their own behaviors, an estimated 42% of all new develop Cancer cases could be avoided.
Age:
Most Cancers cases are associated with aging, when a person lives a longer life; is more likely, that Cancer lead to causing lesions, which accumulate in their cells. Moreover, the ability of their cells to recover and prevent from these defects are weakens with the age. .Heritability: The Cancer cell or tumor is neither hereditary nor contagious. In addition, the susceptibility of increased risk of the developing Cancer was inherited.
Alcohol( Drinking alcohol):
It can increase your risk of Cancer disease of the mouth, throat, esophagus, larynx (voice box), liver, and breast. The more you drink, the higher your risk. The risk of Cancer is much higher for those who drink alcohol and also use tobacco.
Chronic inflammation:
In the chronic inflammation, the inflammatory process may be start even if there injuries, which may be caused by infections, such as abnormal immune reactions to the normal tissues, or other conditions such obesity. With time, the chronic inflammation can lead to DNA damage and cause Cancer Disease.
Hormones:
Some hormones such as Estrogens, is a group of female sex hormones, are considered as hormonal carcinogens. Although these hormones have essential physiological roles in the human body,but also they may be an important cause of Cancer Disease.
Immunosuppression:
Many individuals, who receive organ transplants, can take certain medications to suppress the immune system, so the human body won't reject the transplant organ. The "immunosuppressive" drugs can make the immune system weak, to destroy Cancer cells, or fight the infections that can lead to Cancer.
Infectious agents:
Many infectious agents, including the viruses, bacteria, and parasites, can increase the risk factors of Cancer, or cause Cancer. Also, variety of Infectious agents weakens the immune system, which making the body less able to fight normal cells, that other Cancer causing infections.
Some bacteria, parasites, and viruses, also can cause chronic inflammation, which may cause cancer, for example, Epstein-Barr virus (EBV), Human immunodeficiency virus (HIV), Hepatitis B virus and hepatitis C virus (HBV and HCV), Merkel cell polyomavirus (MCPYV), Human papillomaviruses (HPVS), Kaposi sarcoma- a ated herpesvirus (KSHV), Human T-cell le hia/lymphoma virus type 1 (HTLV-1), H bacter pylori (H. ppylor).
Means Of Prevention Of Cancer disease:
- Parton from smoking and make a decision to stop it, and if the person is difficult to turn off smoking can consult your doctor.
- Farley useful for health: For example : a large amount of vegetables and fruits daily, preservation of healthy weight and not drinking alcohol and minimizing meat processed.
- Exercise regularly.
- Avoid extreme and direct exposure to the sun, especially between 10 am and fourth. In addition, the use of solar protector.
- Access to medical care: Regular tests arguably in early detection of certain types of Cancer Disease such as Skin Cancer, Cervical Cancer, Breast Cancer and others.
