Did You Know What is Cancer? What Causes Cancer?
In our daily life we would often hear about the cancer, there may be friends, companions and also our brother who never had cancer, however, much remains unclear and understand what it was cancer.
It a Cell diseases
For a simple explanation, cancer is the class of diseases associated with cell, a group of cells that can not display its controlled growth (exceeding the normal limits), invasion (intrusion on and destruction of adjacent tissues), and sometimes metastasis (spread to other locations in the body via lymph or blood).
There are more than 100 different types of cancer, and each is classified by type of cell that was originally affected.Almost all types of cancer harm the body when the damaged cells to divide uncontrollably to form a lump or mass of tumor tissue (except in cases of leukemia where the cancer prohibit normal blood function with abnormal cell division in the bloodstream). Tumors can grow and interfere with the digestive system, nerves, and blood circulation, and they can release hormones that alter the function of the body. Tumors that stay in one place and shows limited growth of this type of cancer is generally considered benign.
Cancer cells would be extremely dangerous, or malignant, tumors formed when two things happen:
- Cancer cells to successfully move the entire body using blood or lymphatic system, destroying healthy tissue in a process called invasion
- Successful cells divide and grow, forming new blood vessels to feed themselves in a process called angiogenesis.
The lymphatic system consists of thin tubes that branch, like blood vessels in all parts of the body. Lymph vessels carry lymph, a colorless, watery fluid containing white blood cells called lymphocytes. Along the network of vessels are groups of small, bean-shaped organs called lymph nodes. Clusters of lymph nodes make and store infection fighting cells.
Spleen (an organ in the upper abdomen that lymphocytes and filters old blood cells from the blood), thymus (a small organ under the sternum) and tonsils (an organ in the throat) is also part of the lymph system.
Since there is lymph tissue in many parts of the body, cancer can spread to almost all body organs or tissues as liver, bone marrow (the spongy tissue inside large bones that makes blood cells), spleen, or brain.
AIDS-related lymphoma is a disease in which cancer (malignant) cells are in the lymphatic system disorders in patients with AIDS (acquired immune deficiency syndrome). AIDS caused by human immunodeficiency virus (HIV) which attacks and weakens the immune system. Infections and other diseases that can penetrate the body and the immune system can not fight them.
Lymphoma is divided into two general types of Hodgkin's disease and non-Hodgkins lymphoma, which is classified by how their cells look under a microscope. This provision is histology. Histology is also used to determine which type of non-Hodgkin lymphoma (many). The types of non-Hodgkin lymphomas are classified by how quickly they spread: low-grade, intermediate quality or high quality. In mid-or high-grade lymphomas grow and spread more quickly than low-grade lymphoma.
The main types of lymphoma, Hodgkin's disease and non-Hodgkin lymphoma can occur in people with AIDS. In mid-and high-grade types of non-Hodgkin's lymphoma usually in AIDS patients. Both forms of lymphoma can also occur in adults and children.
When cancer of the adrenal cortex is diagnosed more tests done to see how far the cancer has spread, a process called staging.
Treatment varies depending on which stage of the disease. The following stages are used for cancer of the adrenal cortex:
Phase I - cancer is less than 5 cm (less than 2 inches) wide and has not spread in the tissue around the adrenal. During this phase, the primary treatment is likely to have an operation for cancer.
Phase II - cancer is more than 5 cm (less than 2 inches) wide and has not spread in the tissue around the adrenal. During this phase, the primary treatment is likely to have an operation for cancer, but clinical studies are now underway to test new therapies for this stage of the disease.
Phase III - cancer of the tissues around the adrenal gland or has spread to the lymph nodes around the adrenal. Lymph nodes are part of the lymphatic system disorders, and are small, bean-shaped organs and store infection fighting cells. During this phase can be any of the following:
Surgery for cancer. Lymph nodes in space can also be removed (lymph node dissection).
A clinical trial of radiotherapy.
A clinical trial of chemotherapy if the size of the tumor can be measured by X-ray and / or if the tumor makes hormones.
Phase IV - the cancer has spread to tissues or organs in the area and the lymph nodes around the adrenal cortex, or the cancer has spread to other parts of the body. During this phase can be any of the following:
A clinical trial of chemotherapy.
Radiation to the bone when the cancer has spread.
Surgery for cancer in places where it has spread.
Periodic - The cancer is back (again) after it has been processed. It may come back in the adrenal cortex or in another part of the body. Treatment during this phase depends on several factors, including where the cancer came back and what treatment is received. In some cases, surgery may be effective in reducing symptoms of the disease by removing a part of the tumor. The clinical trials are currently testing new treatments for this phase of the disease.
There are two adrenal glands, one above each kidney in the back of the upper abdomen. Each adrenal gland consists of two layers:
The adrenal cortex, the outer layer of the adrenal, various steroid hormones;
The adrenal PITH or inner layer of the adrenal gland that produces hormones epinephrine and norepinephrine.
Cancer of the adrenal cortex, also called adrenocortical carcinoma, is discussed below. (Cancer of the adrenal PITH, also called pheochromocytoma is discussed separately.)
The cells in the adrenal cortex of important hormones that help the body to function properly. When cells in the adrenal cortex become cancerous, they may make too much of one or more hormones, which can lead to symptoms such as high blood pressure, weakening of the bones, or diabetes. Cancers that hormones are called functioning tumors. However, many cancers of the adrenal cortex hormones and no additional nonfunctioning tumors.
A person with the following symptoms you should seek medical pain in the abdomen, weight loss without diet and weakness. If there is a functioning tumor may cause symptoms or signs caused by too many hormones, such as high blood pressure, weakening of the bones, or diabetes.
If a patient has symptoms of cancer of the adrenal cortex, the doctor for blood and urine tests to see if the amounts of hormones in the body is normal. A doctor may also be a computed tomography scan, a special x-ray optical using a computer to a picture of the inside of the abdomen. Other special x-rays can also be taken to determine the type of tumor is present.
The risk of recovery (prognosis) of cancer of the adrenal cortex is dependent on how far the cancer has spread (the stage of the disease) and a doctor can perform surgery to remove all cancer.
Adult acute myeloid leukemia (AML) is a disease in which cancer cells develop in the blood and bone marrow. AML is also called acute nonlymphocytic leukemia.
Bone marrow is the spongy tissue inside large bones in the body. Bone marrow cells are produced by immature immortal stem cells. These stem cells produce slightly more mature cells called the explosion that the development of (adult) in the following types of blood cells that do specific jobs in the body:
Red blood cells carry oxygen and other materials to all tissues in the body.
White blood cells that fight infection.
Platelets make the blood clot.
Adult acute myeloid leukemia affects explosion which develop into white blood cells called granulocytes. In adult acute myeloid leukemia, the explosion is not mature and become too numerous. These immature blast cells are then incorporated into the blood and bone marrow.
The disease develops rapidly, and the treatment is different for adults than for children.
Do you that green tea can be use to fight a leukemia? In our daily life we know that green tea subjected to many scientific and medical studies to determine the extent of its long-purported health benefits.
Chronic lymphocyte leukemia is the most common subtype of leukemia in the U.S.. There is currently an incurable disease. Unlike most other types of cancer where early diagnosis increases the chance that the patient can be cured, treatment with cytotoxic chemotherapy is associated with increased toxicity but no increase in patient survival.
Despite this harsh reality, there is good news. A study published in the Journal of Clinical Oncology showed patients with chronic lymphocyte leukemia in a phase of an investigation, had a reduction in their lymphocyte in 33% of the participants. By doing this, the team of cancer researchers from the State University of New Jersey, is a positive correlation between green tea and a possible treatment for leukemia.
Several epidemiological studies have shown that consumption of green tea reduced the risk of cancer. Furthermore, prevent the formation of a tumor in animal models of tea, supported their ability to affect fundamental processes such as cancer, angiogenesis and inflammation.
Green tea in a pill is still a long way before the Food and Drug Administration approves it prescribed by your doctor. The counting in the phase 2 and phase 3 studies, we have approximately 4 to 5 years for the commercialization of everything went well. And I am not the cost of these pills.
A drink made with cheap ingredients, tea purchased from local market Defense Mechanisms of these problems. The fact is that food is a drug that we seem quite prepared to take at least three times per day.
Breast cancer is a cancer that starts in the cells of the breast. Worldwide breast cancer is the second most common form of cancer after lung cancer (10.4% of all cancers, both men and women included) and the fifth most common cause of cancer death. In 2004, breast cancer caused 519,000 deaths worldwide (7% of deaths due to cancer, almost 1% of all deaths).
Breast cancer is about 100 times as often in women as in men, but survival is equal in both sexes.
Not knowing what is wrong with our bodies can sometimes be easier than that. Perhaps people think that the way you first hear the heart wrenching words "you have cancer." Fear that you are experiencing now is worse or better than what you have for the past week or so, while you wait for the biopsy report? Maybe not, but there is one thing that is different, you now have control over that fear. Cancer causes anxiety, and you are entitled to your fear.
It is important to remember that yes, cancer can do some terrible things, but one thing that can not do is remove that we are. So it does not matter if you're a fighter in the past now is the time. If something good to say about cancer is that it produces more soldiers than almost any other situation in which a person may face.
All cancer is sad, but if a woman is facing a potential disfiguring as breast cancer, it seems that a double whammy. Maybe it's just the fact that the bottom line is that you can learn to cope with the loss of a breast or both. You can not live with untreated cancer.
