Chemicals
There are several chemicals known to cause cancer and other chemicals are suspected of causing cancer. Irradiation of certain chemicals in foods can increase your risk of cancer after a few years later. For example, exposure to asbestos can cause cancer of the roof of the lungs and mesotelioma (lung cancer, pleural membrane). This risk is even greater if the asbestos factory workers was also a smoker.
Virus
Certain viruses cause human cancers and other viruses suspected of causing cancer. Papilloma virus that causes genital warts (genital) is one cause of cervical cancer in women.
Cytomegalovirus causes Kaposi's sarcoma (cancer of blood vessel system which is characterized by red skin). Hepatitis B virus can cause liver cancer. In Africa, Epstein-Barr virus causes Burkitt lymphoma, whereas in China, this virus causes cancer, nose and throat. It is apparent that some additional factors (environmental or genetic), required to trigger cancer caused by Epstein-Barr virus. Some retro virus in humans, such as the HIV virus, causes lomfoma and other blood cancers.

Causes of Cancer (Food Factors)
Food can also be an important risk factor for other causes of cancer, particularly cancers of the digestive tract. Smoked and pickled foods increases the risk of gastric cancer. Instead, consuming foods high in fiber reduces the chances of colon cancer. Reduce fat to less than 30% of total calories would reduce cancer risk of colon, breast and prostate. Alcohol drinkers have a higher risk of esophageal cancer.
Examples of cancer-causing types of food substances, as follows:
- Coloring and preservatives in foods or beverages
- Heterocyclic amines (HCA) found in meats that are fried or baked
over a prolonged period so overcooked. HCA is a substance causes
cell mutations (mutagens), which stimulates the formation of free radicals. Free radicals or
These oxidants can damage DNA genes.
- Trans Fatty Products Acids as margarine, processed products
hydrogenation.
- Eggs are dry
- Metals such as mercury are often found in contaminated seafood such as:
shellfish, fish and so forth.
- Various processed foods are excessively sweet.

Causes of Cancer (Environmental Factors)
One of the most important cause of cancer is smoking. Smoking increases the risk of lung cancer, mouth, larynx, and bladder. Chemical substances contained in cigarettes is the most dangerous and can cause cancer:
- Asetonnitrit and dioxins
- Nitrogen gas that causes a carcinogenic nitrosamines
- Substance polynuclear aromatic hydrocarbons (PAHs) contained in the tar, a carcinogen and DNA damage
- Polonium
- Carcinogenic acetaldehyde, primarily in the skin
Excessive exposure to ultraviolet sun rays can cause skin cancer. Radiation at the uranium miners have been associated with the occurrence of lung cancer 10-20 years later. Higher risk if the miners also smoked.
Ionizing radiation (which is a carcinogen) is used in X-ray, generated from nuclear power plants and atomic bombs and can reach very long distances. For example, people who survived the atomic bombs on Hiroshima and Nagasaki in World War II, a high risk of cancer of blood cells, such as leukemia.

Cancer Causes (Descendants Factors)
Cause of cancer usually can not be known with certainty because it can cause cancer is a combination of a set of factors, genetic and environmental, that increase the risk of cancer. There are some cancers that are known causes
Descendants of factors
Genetic factors cause some families have a higher risk for certain cancers when compared with other families. For example, women's risk for breast cancer increased by 1.5 to 3 times when her mother or sister had breast cancer.
Some breast cancer associated with a specific genetic mutation, which is more common in some ethnic groups and families. Women with mutations in this gene have a chance of 80% -90% for breast cancer, and 40% -50% for ovarian cancer. Other cancer tends to run in the family is skin cancer and colon cancer.

Cancer and Cancer Types
Cancer is a disease or disorder of the body as a result of body cells that grow and develop abnormally, beyond the acceptable limit and very wild. Condition of cancer occurs when normal cells change with rapid growth, so can not be controlled by the body and are not formed. Cancer can occur in any part of the body. When cancer occurs at the surface of the body, will be easily detected and treated. But when going on inside the body, the cancer will be difficult to know and sometimes have no symptoms. If symptoms develop, usually so difficult to treat advanced stage.
Cancer Types
Some types of cancer that has been known until now is:
Carcinoma
Carcinoma is a type of cancer arising from cells lining the surface of the body or surface of the body channels, such as epithelial tissue such as skin cells, testis, ovary, glands muskus, melanin cells, breast, neck Ahim, colon, tektum, stomach, pancreas and esophagus.
Lymphoma
Lymphoma is a cancer arising from tissues that form blood, lymph tissue for example, lacteal, lymph, various lymph nodes, thymus and bone marrow. Specific lymphomas include Hodgkin's disease (lymph nodes and lymph cancer).
Leukemia
Leukemia does not form a tumor mass, but meet the blood vessels and interfere with normal blood cell function.
Sarcoma
Sarcoma is a cancer support network that is under the surface of the body such as connective tissue, including cells found in muscle and bone.
Glioma
Glioma is a cancer of nervous system, such as glia cells (supporting tissue) in the central nervous system.
Carcinoma in situ
This is a term used to describe abnormal epithelial cells that are still limited in certain areas so it is still considered prainvasif lesion (abnormality / injury that has not spread).

Introduction to Cancer (2)
Cells and tissues of the body continues to function in balance. There are now split, grow and be destroyed and then discarded. Cell or tissue in carrying out its functions can be impaired balance. One of the imbalances that can occur is the existence of a cell or tissue which grow wild and unbiased self-controlled and double grows, so grows the network or abnormal cells called tumors. There are two kinds of tumors:
- Benign tumors
Tumors that are not harmful not only to grow bigger and spread out its network.
- Tumor dangerous
Very different dangerous tumor, called cancer. Cancer is a cell that has lost control and normal mekasime so unnatural growth, wild and often spread far into other tissue cells and damage.
Cancer can occur in various tissues in various orrrgan every body, from feet to head. Cancer cells can be derived from all the elements that make up an organ. In line with its growth, cancer cells form a mass of tissue that infiltrated berbahya nearby tissue or bias spread (metastasize) to other organs.
Into cancer cells through a complex process called transformation. Cancer initially undergo a process of initiation, in which the genetic material change, which will be kenker. Changes can be spontaneous or caused by an element (agent) called the substance a carcinogen. Carcinogenic substances can be chemicals, certain foods (tobacco), viruses, radiation and ultraviolet light, and because factor of mental (psychic).
Genesis for certain types of cancer has indeed been altered. In this case the earlier cancer is often found now become rare.
Age is an important factor in the occurrence of cancer. Some cancers are influenced by age, such as Wilms' tumor, acute leukemia and lymphoma Burkitt lomfositik often attack people who are younger. The cause is uncertain, but one factor that plays quite important is the tendency of offspring (genetic).
But in general, most cancers occur in elderly. Prostate cancer, stomach and colon, most likely to occur after age 60 years (possibility of more than 60%). The increased incidence of cancer may be a combination of increased and increasing duration of exposure to cancer-causing substances (carcinogens) and a weak or declining immune system, particularly T cells and white blood.

Introduction to Cancer
Cancer is a term that is very frightening for anyone who heard it. Cancer is an abnormal growth of cells that invade surrounding tissues and spread to other places. Cancer is a disease that is fatal and can spread to all parts of the body from head to toe, from skin to internal organs. Cancer is actually a term for a dangerous tumor, whereas other tumors are less dangerous tumor. Tumors or neoplasia or neoplasm is an abnormal tissue mass, which are autonomous and beyond the growth of normal tissue. Judging from the way it happened, cancer is divided:
- Cancer Metatastik, ie cancer that has spread from another body part
- Cancer arising from their own networks
Cancer quickly as possible should be detected, because the more rapid diagnosis, treatment with the opportunity to obtain good results for patients can be achieved. Once diagnosed late, the cancer will spread everywhere and the more difficult to cure. In many cases, there is no specific treatment for cancer, so just do the best possible care and keep patients in order to feel comfortable and can live a normal life. To that end, efforts to prevent cancer is absolutely done. Two main points of cancer prevention, namely:
- The physical act
- Measures of mental / psychological
would help overcome the cancer so as not to damage or becomes too late.
Cancer is a dangerous disease, but there is hope for remedy.
