Cancer
Cancer is a disease characterized by a set of cells proliferate abnormally, invade and destroy surrounding tissue and can spread far into the tissue / organs through a process called metastasis. The properties are known as cancer and malignansi that distinguish this cancer from benign tumors (benign tumors), in which benign tumors grow localized, non-invasive, and do not metastasize. Cancer can be of any age, and the risk of getting cancer will increase with increasing age.
Most of cancer due to genetic abnormalities of the material-forming cells. These abnormalities can occur due to the effects of carcinogenic substances (substances that trigger potentially cancer) ATL: tobacco smoke, chemicals, ionizing radiation, and infection of several viruses and bacteria, partly derived from ancestors that caused an error in the process of DNA replication. In summary it can be said that cancer cells derived from cells of tissue / organs of the body’s own previously developed into normal and abnormal.
Risk Factors.
The doctor even if sometimes difficult to explain why in some people can get cancer while others do not.
Research shows that there are a number of factors that can trigger the emergence of cancer known as risk factors.
Risk factors most often lead to cancer are as follows:
1. Age. Although cancer can be of any age, but with age the risk for cancer to be increased.Many cancer that began to appear at the age of 65 years
2. Tobacco. Is the cause of death can not be prevented. In the United States each year 180,000 people die from cancer induced by tobacco use. Both smokers and passive smokers may increase the risk of lung cancer, oral cavity, larynx, stomach, esophagus, bladder, kidney, pancreas cancer and even the cervix, starting with the occurrence of amyloid acute leukemia (a cancer that starts in blood cells). Tobacco users in other ways such as chewing increases the risk of oral cavity cancer.
3. Sunshine. ultraviolet radiation may come from the sun (especially at 10 – 15), UV light. UV rays can accelerate the process of skin aging and skin damage that lead to skin cancer.
4. Ionizing radiation. Radiation from outer space, radon gas, x-rays, can cause cell damage and lead to thyroid cancer, breast, lung, stomach and leukemia.
5. Chemicals. Research shows that such materials abes, benzene, benzidine, cadmium, nickel, or vinyl chloride can cause cancer. Always follow the instructions in the MSDS.
6. Viruses and bacteria. HPV infection can cause cancer of the cervix and the risk factors for several other cancers. HIV can lead to lymphoma (cancer of the lymph nodes) and Kaposi’s sarcoma, Human T lymphocyte virus can trigger leukemia. Hepatitis B and Hepatitis C after several years of infection can cause liver cancer. EBV can trigger lymphoma. HHV can trigger Kaposi’s sarcoma and Helicobacter pylori can lead to stomach cancer and lymphoma.
7. Hormonal drugs may increase the risk of breast cancer
8. History of cancer in the family. Most cancers grow because of changes / mutations in the gene, and these mutated genes will increase the risk of cancer. These mutated genes can be passed to the next generation. The most common is breast cancer, ovarian, prostate and colon.
9. Alcohol. Consuming alcoholic beverages more than 2 times a day can increase the risk of oral cavity cancer, esophagus, larynx, liver and breast.
10. Unbalanced diet, less physical activity / exercise and being overweight. Research shows that consuming foods high in fat can increase the risk of colon cancer, uterus and prostate.Lack of activities and sports and badab overweight (overweight) can increase the risk of breast cancer, colon, kidney and uterus.
We can protect ourselves with as much as possible to avoid the risk factors above. If we feel have a cancer risk factors, you should consult with your doctor to discuss ways to reduce the risk factors
Some of the above factors may jointly cause normal cells turn into cancer cells, but must always be remembered that:
1. Not everything causes cancer
2. Cancer is not caused by accident, collision or friction
3. Cancer is not contagious disease, although there are several factors can trigger contagious
4. have one or more risk factors are not necessarily going to cause us to have cancer
5. Some people are more vulnerable to risk factors other than
Detection
Cancer detection can be done through the examination of how the way in imaging / radiology (eg, CT scans, ultrasound, MRI, PTA, SPECT, Mammography, etc.) and laboratory (Pap’s smear, tumor markers, cancer genetics), etc..
Choice of method depends on the type and location of the cancer and the effects on surrounding tissue.
Some types of cancer can sometimes be detected early through a medical examination / medical check-up routine
The earlier cancer is detected, the lower the stadiumnya the treatment success rate is getting higher.
Medical
Cancer treatment is not always easy, even a fairly stable and difficult low success rate, this treatment effect disebakan because not only affects the cancer cells but also can memyebabkan adverse effects on cells of tissue / organ that is still normal, and most of the new cancer detected in the advanced stages.
Cancer treatment can be done with Operation, Chemotherapy, Radiotherapy, Imunotherapy and monoclonal antibody therapy. Treatment options is determined by the location and gradation of the tumor and stage of disease.
Operation in theory could lift all cancer cells, but sometimes difficult when already happened metastasi, so sometimes after surgery should be followed by other treatment methods eg.chemotherapy and radiotherapy.
Prevention is always better!
In broad outline can be avoided through Behavior and Environmental Factors
Factors Conduct
1. Do not use products containing tobacco
2. Not consume excessive alcohol
3. Eat vegetables and fruits at least 5 times a day
4. Eat foods that are not fatty
5. Consuming foods with calories appropriate to the physical needs
6. Maintain ideal body weight
7. Active / regular exercise
8. Protect your skin from the sun
Environmental Factors
1. Avoid environmental tobacco smoke ( “passive smoking”)
2. Control use of pesticides
3. Be careful with Dioxins (Tetracloradibenzo-p-dioxins)
