What We Protect Food?
About 15 years ago that scientists around the world began to review the evidence that linked the role of the diet with the appearance of certain types of cancer.

Since then many studies and investigations that seek to assess the role of foods as protective against cancer or, conversely, its potential carcinogen. Some of the more established faiths have been subsequently disproved latest figures and some supposedly protective substances have been maligned later.

Reviewing The Global Panorama

The majority of cancer cases could be avoided with some changes in the current Western lifestyle. Alcohol, snuff, a diet with excess fat or weight above normal are some factors that may favor the emergence of this disease.

The statistics indicate that poor nutrition is responsible for up to one third of cancer deaths. Specifically, this international organization argues that a proper diet may help prevent half the breast cancer cases and three out of four tumors of the stomach and colon.

Thus, they add, eat at least five portions of fruit a day could reduce cancer incidence by 20%, a figure that could rise to 40% with a combination of exercise, diet and weight varied ‘right’. However, the population often stubbornly resist any change in their lifestyle if it detects an immediate benefit, such as weight loss, for example.

Although this recipe does not offer a guarantee in itself directly against the disease (more than 200 different tumor types really), scientists are convinced of the bad influence of current lifestyles.

Proof of this are the developing countries, where the tumors are still much rarer than in the First World. In the U.S., for example, several studies have shown that Asian populations migrating to that country begin to develop tumors at much higher rates in their countries of origin.

Does the diet to blame for this? Or is that your original feed protected them in any way? It appears that the answer to both questions is yes. In fact, the world map of cancer varies considerably from region to region, with some recognizable patterns.

For example, developing countries in Africa, Asia or Latin America (with a power basically dominated by cereals) boast high rates of cancer of the mouth, esophagus, larynx, stomach, liver and cervical cancers, while in Europe, North America and Australia (with diets rich in fats and processed foods), the most common are usually of colon, prostate or breast. Lung, directly linked with the consumption of snuff, is in first place worldwide.

Testicular cancer, for example, tends to affect men more than young adults. Read on to learn more about the types of cancer that can affect adolescents.

Cancers that occur in adolescence, have one thing in common: cells, the basic components of the human body. Cancer occurs when cells develop abnormally and grow uncontrollably.

This article contains information about the types of cancer that teens may face, including warning signs and symptoms and possible treatments for these cancers.

While not common, other cancers that may be suffered by adolescents are testicular cancer and rhabdomyosarcomas.

Although testicular cancer is rare in adolescence, is the most common cancer in men aged 15-35 years. If detected and treated early, testicular cancer is almost always curable.

The boys must learn to examine their testicles regularly to detect any abnormal lump because it is often the first sign of testicular cancer.

Rhabdomyosarcoma, or soft tissue sarcomas are less common cancers that mostly occur in infants, children and adolescents. In these types of cancer, cancer cells grow in the soft tissues of the skeletal muscles (the muscles of the body we use to control movement).

Although these cancers can occur anywhere in the body, rhabdomyosarcomas most frequently occur in the muscles of the trunk, arms or legs. The types of treatment used and chances for recovery depend on the location of rhabdomyosarcoma and whether the cancer has spread to other parts of the body.

The role of the lymphatic system is to fight the germs that cause infection and disease. Most adolescents with lymphoma have Hodgkin’s disease (cancer of the lymph tissue) or non-Hodgkin lymphoma (cancer of immune system cells that circulate in our bodies).

Hodgkin’s disease usually occurs in adolescents and young adults. May arise in lymph nodes in the neck, armpits, chest or other parts of the body. Lymph nodes were enlarged but are usually not painful.

Hodgkin’s disease is characterized by the presence of large abnormal cells, called Reed Sternberg cells are detected with a microscope after a biopsy (a procedure in which a doctor takes a small tissue sample for the presence of cells cancer). Chemotherapy and often radiation are used to treat Hodgkin’s disease.

The non-Hodgkin lymphoma is similar to leukemia (ALL) because both are characterized by the presence of malignant lymphocytes (white blood cells in the lymph nodes) and because they share many symptoms. Non-Hodgkin lymphoma treated with chemotherapy.

Most adolescents with Hodgkin’s disease or non-Hodgkin lymphoma and complete treatment a complete remission with no signs of the disease.

Most brain tumors in adolescents are primary. Two of the most common forms are astrocytomas and ependymomas. Astrocytomas are brain tumors that originate in the brain cells called astrocytes.

This type of tumor does not usually spread outside the brain and spinal cord, and usually does not affect other organs. Ependymomas are tumors that usually begin in the lining of the ventricles of the brain.

The brain has four ventricles, or cavities, that are a pathway for cerebrospinal fluid, a liquid substance that protects the brain and spinal cord, and absorbs shock.

No one knows exactly what causes primary brain cancer. One possibility is that a problem occurred with the cells into the brain and spinal cord.

Treatments vary depending on the type of tumor and its location. If possible remove a tumor, surgery is usually performed, followed by radiation. Some patients also receive chemotherapy.

The odds of surviving a brain tumor depend on the type, location and treatment. But if it is possible to remove the tumor and additional treatment, it is likely to cure cancer.

Because these abnormal blood cells are defective, they do not help protect the body against infections, as do normal white blood cells.

And because they grow uncontrollably, they take over the bone marrow and interfere with the production of other types of cells important to blood flow, as red blood cells (which carry oxygen) and platelets (which help blood clot) .

Leukemia causes problems like bleeding, anemia (low red blood cell count), bone pain and infections. You can also spread to other parts of the body such as lymph nodes, liver, spleen, brain and in the case of men, the testicles.

The most common types of leukemia in teens are acute lymphocytic leukemia (ALL) and acute myeloid leukemia (AML).

Virtually all persons with ALL and AML are treated with chemotherapy and some also receive stem cell transplants. During this procedure, given new stem cells from another person.

Bone marrow transplants are a common form of stem cell transplantation. Some people also receive radiation. The duration of treatment and types of medicine given will vary depending on the type of leukemia.

The chances of cure of certain types of leukemia are very good. With proper treatment, most patients with ALL and many patients with AML are cured of the disease and it does not reappear.

Treatment for osteosarcoma usually involves chemotherapy (medication intravenously, or IV, which destroys cancer cells) as well as surgery to remove the tumor. In a few cases in which these procedures fail to fully overcome the cancer, the doctor may need to amputate a part or all of the limb to fight cancer.

Doctors can also perform surgery for limb salvage. In this intervention, the bone is removed to prevent cancer and the amputation of the limb by filling the space with a bone graft or a metal rod special.

The loss of a limb can be devastating, especially for teens who are going through other bodily changes. The psychological and physical therapy (also called “physical rehabilitation) can be very useful in this situation.

In general, adolescents who are receiving must practice amputation prosthesis or artificial limb, to help them adapt. Most adolescents are able to return to normal activities, including sports.

Most people develop side effects such as hair loss, bleeding, infection and heart or skin problems, from medicines used in chemotherapy treatment for osteosarcoma. Chemotherapy may also increase a patient’s risk of developing other cancers in the future. The good news is that most teens with osteosarcoma do recover.

Ewing Sarcoma

Another type of cancer that affects the bone is Ewing’s sarcoma. It is similar to osteosarcoma in that it also affects adolescents and young adults, and usually in the leg or pelvis.

Most teens with Ewing’s sarcoma receiving chemotherapy and undergoing surgery. Some patients also need radiation in addition to surgery or in lieu thereof, to be sure to destroy the remaining cells. Ewing’s sarcoma generally responds well to chemotherapy and radiation.

Osteosarcoma and Ewing’s sarcoma share common risk factors and the same side effects of treatment. Chances for recovery depend on the location of the tumor, its size and whether it has spread. But both types of bone cancer respond well to treatment and, in many cases are curable.

Osteosarcoma affects twice as many boys than girls and often occurs in people with higher than average.

Some medical problems may be due to genes, such as retinoblastoma, a tumor that develops in the retina, may predispose some adolescents to develop osteosarcoma. The same happens if a teenager has received radiation treatments for other bone cancers.

The most common symptoms of osteosarcoma are pain and swelling of the legs or arms, sometimes accompanied by the appearance of a package. Some people suffer more pain at night or when exercising.

Often, osteosarcoma is found in the bones around the knee, but can also occur in other bones.

In exceptional cases, a tumor can spread or metastasis outside the bone, nerves and blood vessels of the limb. (The word metastatic disease is the term doctors use when cells from a tumor break away from the original cancer site and move to different tissues or organs).

Operation – treatment for the type of Mesothelioma cancer is not very useful, and in many cases. But if the surgery with chemotherapy and radiotherapy in combination, is a success. Chest wall can be removed by surgery, but the lining of the lung is very difficult to remove.

Radiation – Radiation is for patients who have radiation therapy and some of the main reasons for the success of treatments for Mesothelioma cancer than people who are patient and can tolerate a prolonged life for more than 5 years of recovery. Joint Radiation with chemotherapy is more useful than radiotherapy alone. Many doctors and hospitals to use radiation and chemotherapy for cancer patients treated with mesothelioma.

Chemotherapy – Chemotherapy is the only treatments for Mesothelioma cancer is known to mesothelioma cancer has shown remarkable and shows significant signs of recovery in patients. Some patients who had chemotherapy, showed a good recovery and improve the lives of more than one year. Chemotherapy is currently the only treatment for patients with temporary cure mesothelioma.

Immunotherapy – therapy, the patient came in the immune system, without increasing, so that they can prevent cancer. This treatment has shown some positive aspects in relation to the treatment, but the practice of immunology has been suspended since the patients with side effects from this treatment.

Many people died because of disease, and many victims of this tumor. The researchers are still trying to find a cure for this cancer… Mesothelioma is a rare cancer, but very dangerous and there is no cure for this disease. Some developed countries like the United States continued to try to find a cure, but it was rather difficult, “doctors find a cure. But even people with mesothelioma cancer can live a little” about the possibility of treatment. For more information, contact your doctor about the best way to do things in a particular case.
