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.
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.

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.
Self Detect Prostate Cancer by knowing the right symptoms
Prostate cancer is now become one the most disease that men always worried. Some of them regularly meet the doctor just to make sure that he is free from prostate cancer. Since the cause of this disease cannot exactly predict, then the best way we can do is how to prevent and or to fight it.
There are more than 15% of men affected by prostate cancer, and most of them didn’t know about the risk factor associated with the permit. Actually we could prevent the disease from the beginning just like healthy diet, maintain weight, routine exercise and activities controlled.
For the rest that are unaware, know the signs. There are 13 possible symptoms that indicate you have prostate problems and you don't have to get those symptoms to start with prevention.
Knowing it symptom early is the best way to prevent, you have to understand it and read a lot related article yourself on the internet, book or anything. Here is the list of possibilities related to prostate cancer, if you feel one of them match, soon meet your doctor:
1. You have a burning sensation when urinating
2. You wake up all night due to the constant need to urinate at night
3. You have trouble with a weak urine flow
4. You feel your bladder is not completely empty
5. You get a pain, hesitancy or urgency to urinate
6. You get blood in your urine
7. You experience lower back pain
8. You can't feel comfortable on a chair
9. You get pain in the testicles groin or penis
10. You feel pain during sex
11. You have a constant itchy feeling in your penis
12. You need the blue pill to get an erection or impotence
13. You sex drive at zero

There are a large number of potential cancers that a person can have. Skin, lungs, pancreas, brain, oesophageal, and virtually all other tissues can develop tumors that are carcinogenic. Despite the large number of cancers particularly the fact that they all fatal if untreated, not all cancers, if treated, have the same mortality.
The mortality rate is the percentage of people who develop a certain type of cancer that later killed. It can be stored in the drawing for the five years, ten years the brand, and so on. One of the misleading facts to track is the mortality that a person can die due to other causes. Since people usually develop cancer later in life, it is a very real possibility that a person successfully treated for skin cancer on 60 May to die of another cause of the time he or she hits 80.
Overall, pancreatic cancer is the most lethal form of cancer. Fortunately, it is not very common form of cancer. In 2008 there were 37,000 new cases of pancreatic cancer. Although this may sound high, it was more than one million non-melanoma skin cancer cases in the same year. Unfortunately, more than 90% of all people diagnosed with pancreatic cancer will die before five years mark. This is usually due to not an effective test for the disease will appear at an early stage. Since there is no test for the disease, by the time a person goes to the doctor with symptoms is usually too late.
Lung cancer is a deadly form of cancer. Approximately 75% of all people diagnosed with a form of lung cancer will die before five years mark. Lung cancer is dangerous because it has a huge potential to spread to other parts of the body quickly. Furthermore, it is not typically a potential treatment for the removal of a person in the lungs. Fortunately, about 80% of all people diagnosed with lung cancer or smoking. This means that persons who have not lived with smokers and never smoked a less likely chance of this group. The remaining 20% of cases depends on a number of other reasons, such as exposure to asbestos.
Leukemia is a cancer with high mortality. Of the people who are diagnosed with leukemia, approximately half will die. These data are somewhat misleading, since there are many forms of leukemia. Some forms of leukemia are harder to treat than others, and just because a person diagnosed with leukemia does not mean that the person has a 50/50 chance in five years.

The cells are fundamental components of all living creatures. The human body consists of billions of cells. They give structure to the body, absorb nutrients from food, convert these nutrients into energy, and to perform specialized tasks. Cells also contain the body hereditary and can make copies of them.
Cells have many parts, each with a different function. Some of these parts, so-called body or, specialized structures that perform certain functions in the cell. Human cells contain the following elements, in alphabetical order:
Cytoplasm
Inside the cell, the cytoplasm consists of a jelly-like fluid (called cytosol) and other structures surrounding the nucleus.
Cytoskeleton
The Cytoskeleton is a network of long fibers which form the structural framework of the cell. The Cytoskeleton has many features, including the determination of cell shape, is involved in cell division, and allows the cells to move. It also provides a track-like system that handles the transport of bodies and or other substances in the cells.
Endoplasmic reticulum (ER)
This process helps the body or created by the molecules in the cell. The endoplasmic reticulum also transports these molecules to their specific destination within or outside the cell.
Golgi apparatus
The Golgi Apparatus packages molecules processed by the endoplasmic reticulum to be transported outside the cell.
Lysosomes and peroxisomes
These organelles are recycling center of the cell. I digest foreign bacteria that invade the cells, cells to eliminate toxic substances and reusing worn out cell components.
There are still lot more like Mitochondria, Nucleus, Plasma membrane and etc.

Colorectal cancer is the 2nd most common cancer in both sexes - one of 20 people
develops the disease during their life. As always, is also one of the most preventable cancers. Regular screening is important, especially for those at risk.
Each organ and tissue in the living body is composed of small blocks called cells. Normal cells in the body grow at a constant speed and controlled. New cells are normally formed to replace worn out cells or to repair damaged cells. Sometimes some of these cells multiply out of control and have the propensity and ability to spread in an unusual manner to other organs and tissues, these cells then use the body reserves so as to destroy the function of the body.
These abnormal cells are called cancer, and growth is a group of abnormal and uncontrolled cell. Cancer so results in a situation of severe malnutrition and the general malfunctioning organs affected. Moreover, tumor cells have the ability to spread beyond the original site of cancer growth or tumor malignant tumors not only grow a good original location of the cancer growth. Malignant tumors (also called primary tumor), but the cells can travel to other organs and form secondary tumors.
Such growth is called secondary metastases and the ability to form such a metastasis is a sign of a malignant tumor. Colorectal cancer comes from the innermost of the feed in the wall of the colon and rectum. Epithelia llining This is also called the mucosal layer of the colon.

A cancer that grows very quickly in human body called angiosarcoma. Angiosarcoma is a malignant, highly invasive cancer. The thin layer of Endothelium feed called, where there is endothelial cells lining the walls of blood vessels and tumors begin to form here. The cells reproduce more rapidly in cells and these cells can reverse cancer. They can also spread through the body. Like other forms of cancer, the replication of cells is uncontrollable. The connection to the circulatory system threat of the people’s health.
Hemangiosarcoma is an aggressive sarcoma. It affects blood vessels and is very dangerous. The growth of blood vessels in the tumor and the crimes of this will cause a victim to bleed to death. Conditions that have an effect on the blood are very dangerous. How cancer cells spread, probably second healthy body will be affected. Angiosarcoma is difficult to treat because it is destructive and often come back.
Lymphangiosarcoma is an angiosarcoma. The tumor cells are endothelial cells in lymphatic vessels. The lymphatic system is responsible for the distribution of antibodies in the whole body. A devastating truth is that when a cancer that affects the body, such as blood or lymph, is to develop a fatal cancer in the whole body.
Angiosarcoma is common in skin or soft tissue can take place in all organs of the body. They may begin in the liver, breast, spleen, bones and heart. Located in the neck and head older, cutaneous angiosarcoma is the most common angiosarcoma.
What is the cause of angiosarcomas is unknown and is a factor in understanding what is angiosarcoma. Hemangiosarcomas just like Stewart - Trèves syndrome associated with exposure to toxins thorium dioxide, vinyl chloride or arsenic. Stewart-Trèves syndrome is caused by lymphedema. This comes after the breast care treatments such as mastectomy and radiotherapy. If a person has been exposed to vinyl chloride in the industries of plastics in the manufacture of polyvinyl chloride, have a higher risk than that of angiosarcoma. Exposures that occurred 30 years ago are stilling effects that would follow.
Each type of angiosarcoma can be destructive and multicentric. The rate of relapse is very high, and cancer is more likely to spread to another part of the body. It is a pity that many cases diagnosed that mortality is higher. The common treatments such as chemotherapy and radiation do not work well with these aggressive tumors that this condition is difficult to treat.
The test is investigated by researchers of the changes happening on p53, the tumor SUPPRESSOR genes in the cells of angiosarcoma of the liver. Tumor SUPPRESSOR p53 and molecules on the focus of today's researchers. Thousands of studies are ongoing around the world. New treatments can be discovered to help this deadly cancer.

Can not be denied that breast cancer is one of the biggest bugbear for the women in the world. Every woman has the same risk of disease, old age, even a young age still go to breast cancer.
Breast cancer is one in ten women suffer from cancer in the world. The risk of this disease is higher as you get older. Unlike other cancers, however, early detection of symptoms of breast cancer is easier.
It is always important arm with the right knowledge. To protect yourself, be aware if you experience any of these early symptoms of breast cancer:
1) the tenderness in the breasts
Most women experience breast tenderness during their monthly cycle; it is natural for the remainder of its regular agenda. If you have to raise the issue, perhaps it is time for a mammogram.
2) Unusual lump in the breast
one of the most common early symptoms of breast cancer is the presence of an unusual lump in the breast. Women have learned to give them a self-examination of the breasts, to feel for any impact on the breast or armpit. This lump can be benign or malignant. However, it is not a good idea to take a risk. Occurred immediately.
3) Discharge from the nipple
during the early stages of breast cancer, you may notice a strange out of the nipple. This may be bloody, yellow or green. Whatever the color may be, it is important that you go see a doctor once. Breast cancer can progress very rapidly, so the earlier you see a doctor, the better.
4) Swelling of the breast
Like breast tenderness, something like this can occur naturally in women during the days her cycle. This is one reason why doctors encourage the use of a monthly self-breast examinations. In this way you will be able to see how much of a difference in your breast size and have a check-up immediately if you notice any of the early symptoms of breast cancer.
5) Change in Texture
Do monthly self-exams also help to identify a change in the texture of your breasts. Was looking for redness of the skin to skin or dimpling is. Be very sensitive to the withdrawal of the nipple or the presence of an orange peau'd. Peau'd An orange refers to a breast similar to skin an orange.
If there is anything wrong, your body tells you in the form of symptoms. So do not take these early symptoms of breast cancer for granted.

The shock of knowing that your doctor has diagnosed your illness such as cancer can be a chilling experience. Not only was worried, but your family and friends are also worried and concerned, too. They want the best for you and to receive news about cancer is devastating. Cancer is not to respect people. It affects rich and poor alike. In our modern society, almost all have a family member or a relative who died of this disease.
Of course, you can try to put on a happy face and pretend that everything will work fine. Crying on your condition of depression and despair is not the best approach. Most therapists do not recommend venting your feelings by crying for hours.
What we propose is necessary to see life as a journey. Each trip includes sightseeing. All part of life for pain and suffering to some extent, and the key to be positive is to accept this reality.
- Acceptance is the key to managing the disease, including cancer.
- Acceptance is the key to self-knowledge.
Provided for the approval of reflection and to know your journey through life. You can see with greater perspective that your life was not bad and not everything was good. Approval, you can take a step back from the drama of life and see what is really important.
