New studies on cancer
With the aim of lowering the number of people who die from cancer each year are conducted several studies and conferences in which health professionals discussed different ideas and alternatives to cope with the disease. Recently, the National Cancer Institute in Washington, United States, announced it will begin to work with various researchers to try to give answers to the questions that still could not be resolved.
The main idea is to understand why the expansion (metastasis) of the tumors and then prepare a more effective method of combat, which would transform the chronic cancer using tools such as targeted therapy. The goal is simple: raise the quality of life and ensure that the percentage of fatal cases of cancer begins to decline.
Researchers and doctors are still very cautious and do not want to raise false expectations. However, it is noteworthy that opens in a new light for patients who suffer from some form of cancer. At first you probably will not achieve drastic changes in terminal cases, but it is possible to increase the quality of life, which it remains more than positive news.
Eating watercress would slow the growth of breast tumors
Eating watercress often help prevent the development of mammary tumors . This was revealed by a recent study conducted by scientists at the University of Southampton, England.
The research says that the watercress leaves contain phenylethyl isothiocyanate, a factor which can slow the growth of cancerous polyps in the breast. This property, which is what gives it its unique taste to watercress to “pepper”, is acting as blocking a protein that promotes tumor growth.
For the study the scientists called for 80 volunteers who ingested 80 grams of watercress per day. Among those who participated in the test found that all had elevated blood level of anti-cancer molecules past a few hours after eating a salad made from that plant.
The tumors usually develop rapidly and usually exceed the levels of blood but the phenylethyl isothiocyanate restricts the ability of oxygen, which in turn manages to limit the spread of cancer cells. The cancerous tissue by blood sends signals that stimulate the growth of healthy cells, through Hypoxia Inducible Factor protein (HIF), located in the central part of this process.
It is precisely where the beneficial element acts containing the watercress, in an absolutely natural, blocking the function of this protein harmful. Research carried out by British scientists was funded by the Watercress Alliance company and published in the British press.
Liver tumors
liver tissue are called, primitive liver tumors, benign or malignant, while those affecting the body but are originated in other organs are secondary liver tumors or liver metastases.
There are focal lesions such as simple cysts or hepatic peliosis can not be categorized strictly liver tumors. Simple cysts are a relatively common ultrasound finding, are usually asymptomatic and require no treatment, in rare cases can be justified via percútanla drainage under ultrasound guidance or by laparoscopic surgery.
Hepatic peliosis is very rare injury consisting of the formation of cavities lined by hepatocytes and contains blood is usually asymptomatic, does not induce laboratory abnormalities and their occurrence has been associated with hematologic malignancies or with the administration of drugs such as anabolic steroids or aziatropina.
In childhood malignancies are the most common primary, mainly hepatoblastoma, whereas in adulthood are more frequent metastases, and hepatocellular carcinoma (HCC) the most prevalent primary tumor. Hemangioma is the most common benign liver tumor, while others are very rare.
Clinical Trials
Clinical Trials
Anal cancer stage I was formerly treated with abdominoperineal resection. Current therapies in preserving the sphincter include wide local excision of the perianal skin or anal margin for small tumors, or definitive chemoradiation (fluorouracil, and mitomycin) for cancers of the anal canal. Salvage chemoradiation therapy (fluorouracil and cisplatin plus a radiation boost) may avoid permanent colostomy in patients with residual tumor after undergoing initial nonoperative therapy. Radical resection is reserved for patients with incomplete responses or recurrent disease. It is therefore important continuous surveillance with rectal examination every three months during the first two years and endoscopy / biopsy when indicated after completion of sphincter-preserving therapy.
Standard treatment options:
1. Small tumors of the perianal skin or anal margin not involving the anal sphincter may be adequately treated with local resection. Read the rest of this entry »

Anal Cancer
GENERAL INFORMATION
Anal cancer is often curable. The three major prognostic factors are site (anal canal versus perianal skin), size (primary tumors less than 2 cm have a better prognosis) and differentiation (well differentiated tumors have a better prognosis than tumors with poor differentiation).
Anal cancer is an uncommon malignancy that represents only a small percentage (4%) of all cancers of the lower digestive tract. Some clinical trials have evaluated the role of chemotherapy, radiotherapy and surgery in the treatment of this disease. If you need information about ongoing clinical trials of the NCI.
In general, the risk of anal cancer is increasing, and there is evidence that individuals with human papillomavirus and gay men in particular are at increased risk of autism.

What Are The Gynecological Tumors?
The ovaries are two and are i
n the pelvis, one on each side of the uterus. They have the shape and size of an almond, and both produce eggs and female hormones (estrogen and progesterone) that are responsible for shaping and feminine traits to the body and regulate menstruation and pregnancy among other things. Ovarian cancer accounts for 4% of tumors that affect women. Read the rest of this entry »
Lung Cancer
Cells are the smallest living units of the human body. One function is to reproduce and die when no longer useful. This process is very neat, in time and space, so there is always that allows the appropriate number of cells for each stage of life.
When this multiplication of cells occurs in an uncontrolled manner, forming lumps. These masses are called tumors.
There may be benign and malignant tumors. Benign tumors are those that do not spread to other areas and do not compromise a person’s life. Read the rest of this entry »
Pancreatic Cancer
Th
e pancreas plays an important role in the digestive process, producing essential enzymes in the digestion of food. The other function of the pancreas, which can be described as “control of fuel,” is to produce insulin, which affects people with diabetes. Over 95% of the cells of the pancreas are exocrine glands, responsible for producing pancreatic juice that contains enzymes that break down fats and proteins in food so that nutrients can be absorbed by the small intestine and used by the body to repair tissue or to promote growth.

Non-Hodgkin lymphomas (NHL)
Non-Hodgkin lymphomas (NHL) are a group of syndromes of the lymphatic system. You can say that is a cancer that occurs in this system.
It is the fifth mos
t common cancer type. In the United States last year, some 55,000 cases were diagnosed and 26,000 deaths occurred.
The lymphatic system is a system consisting of vessels and to carry lymph nodes.
Lymph is a colorless fluid containing white blood cells.
The three main types of white blood cells are monocytes, granulocytes and lymphocytes. Read the rest of this entry »
