‘Tumors’

Tumor can be Benign or Malignant

Tuesday, April 27th, 2010

Tumor can be Benign or MalignantA tumor is any alteration of tissue that results in an increase in this volume. In simple words, a lump is any lump that is due to an increase in the number of cells.

A tumor can be benign or malignant.

What matters is that benign tumor cells do not spread to other parts of the body. Cells from benign tumors in addition to always stay together, they are often surrounded by a membrane.

Malignant tumors can invade and damage tissues and organs near the tumor, or discard it and travel long distances

Causes and Risk Factors

In general, tumors appear when there is a problem with cell division. Generally, the division of cells in the body is controlled by a very strict so-called Oncogenes or protooncogenes. (more…)

Signs and Symptoms Endometrial cancer

Friday, April 16th, 2010

Signs and Symptoms Endometrial cancerEndometrial cancer is sometimes called uterine cancer because the vast majority of tumors are generally in the myometrial layer, but other cells in the uterus that can become cancer, such as muscle or myometrial cells. These cancers are much less common so-called sarcomas.
Endometrial cancer is often detected at an early stage because it frequently produces vaginal bleeding between periods or after menopause.

Signs and symptoms

• Any bleeding after menopause
• prolonged periods or bleeding between periods
• An abnormal bloody discharge from the vagina
• Pelvic pain
• Pain during intercourse
• Unintentional weight loss (more…)

Symptoms Thyroid Cancers

Tuesday, April 13th, 2010

Symptoms Thyroid CancersRates of thyroid cancer appear to be growing, but doctors think it may be due to new technology that allows them to find small tumors that went more unnoticed.

Symptoms

Thyroid cancer usually causes no signs or symptoms of the disease early. When thyroid cancer grows, it can cause:
• A lump can be felt through the skin in the neck
• Voice changes, including increased hoarseness
• Difficulty swallowing
• Pain in the neck and throat
• Swollen lymph nodes in his neck

Thyroid cancers

• papillary thyroid cancer: The type of papillary thyroid cancer is most common, accounting for about 80 percent, can occur at any age but is most commonly diagnosed in people 30 to 50.
• Follicular thyroid cancer: Includes Hürthle cell cancer, usually occurs in people over 50 years.
• medullary thyroid cancer: Medullary thyroid cancer may be associated with inherited genetic syndromes, including tumors in other glands. (more…)

Cells that can Activate Cancer Cells in The Brain

Thursday, April 1st, 2010

Cells that can Activate Cancer Cells in The BrainScientists have discovered two genes that may be responsible for the most aggressive form of brain cancer.

The glioblastoma multiforme rapidly invades the brain, causing inoperable tumors, but experts do not yet understand why the brain is so agresivo.

In the latest study by a team of Columbia University, USA, and published in the journal Nature, is located two genes that seem to work in pairs to activate other cells that cause cancer.

Researchers say the discovery raises the hope of developing a cancer treatment.

Genes, C / EPB and Stat3, are active in 60% of patients with glioblastoma.

Patients who participated in the study who showed evidence of both active genes have died within the first 140 days of diagnosis.

While half of the patients with inactive genes remained alive after the time passed.

Master Control

The study leader, Antonio Iavarone, said that “when (the genes) are activated simultaneously work together to activate hundreds of genes that turn other brain cells in a highly aggressive and migratory cells,” he said.

Remove both genes simultaneously, with the help of a combination of drugs, can be a powerful therapy for such patients, for whom there is no satisfactory treatment (more…)

Fundamental Characteristics of Cancer-fighting foods

Tuesday, March 23rd, 2010

Fundamental Characteristics of Cancer-fighting foodsExperts say that 50% of the tumors can be prevented with proper diet. Prevention is always better than cure and in the case of serious diseases like cancer, it is very useful to fill the kitchen with foods that are proven to have anticancer properties and not far from the food we daily. Integrate them as much as possible.

Fundamental characteristics of cancer-fighting foods

1. Olive oil:

The monounsaturated fats protect the colon-rectum cancer. By working on bile acids, olive oil reduce the risk of gastrointestinal mucosal growth. Do not forget that the arteries remain flexible to improve circulation and oxygenation of the entire network.

2. Water:

There is food, but we can not live without it. Water makes your cells alive, regulate many functions and help to eliminate toxins through urine and feces.

3. Garlic and onions:

Garlic and onion contain “allicin, a sulfur-rich compounds that act as scrubbers liver, eliminate toxic substances that accumulate in the blood and tissues. (more…)

How the Relationship Between Cancer with Stress

Sunday, March 21st, 2010

China and the first U.S. scientific research shows that there is a direct relationship between cancer and stress.

Studies show edition was published in the journal Nature, the scientists say where the victim cell stress signals that promote tumor that affects the generation of healthy cells around it.
The study was conducted on fruit flies, but studies show that the same genes and the same biological sequences involved in this process present in humans.

So far, it is known that chronic inflammation, the main cause of stress, associated with tumor growth in cancer patients and some experts argue that the negative emotions, stress hormones, inflammation and cancer may be related to each other, although there is no clear evidence.

There is also a consensus that cancer-causing genetic mutation affecting only individual cells, but these studies show that this does not always happen, as various mutations in different cells can collaborate with each other in the generation and development of tumors. (more…)

What Causes a Cerebral Aneurysm

Tuesday, March 16th, 2010

A cerebral aneurysm (also known as intracranial or intracerebral aneurysm) is a weak or thin in a cerebral blood vessel that protrudes like a balloon and filled with blood. The outgoing aneurysm can put pressure on a nerve or surrounding brain tissue. They may also lose or break, spilling blood into surrounding tissue (called a hemorrhage). Some cerebral aneurysms, particularly the very young, do not bleed or cause other problems. Cerebral aneurysms can occur anywhere in the brain, but most are located along the loop of arteries that run between the underside of the brain and skull base.

What causes a cerebral aneurysm?

Most cerebral aneurysms are congenital, due to an inborn abnormality of an artery wall. Cerebral aneurysms are more common in people with certain genetic diseases such as connective tissue disorders and polycystic kidney disease, and certain circulatory disorders, such as arteriovenous malformations .

Known Brain Tumor

Monday, March 8th, 2010

Brain tumors are rare in adolescents. There are two types of primary brain tumors that originate in the brain cells, and secondary brain tumors, which originate from a cancer that started elsewhere in the body (eg, osteosarcoma) and extends to the brain.

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 tumor is rarely spread outside the brain and spinal cord, and usually does not affect other organs. Ependymomas are tumors that usually begin in the walls of the ventricles of the brain. The brain has four ventricles, or cavities, which are a way for cerebrospinal fluid, a liquid substance that protects the brain and spinal cord, and absorbs shock. (more…)
