More risks than benefits

The consumption of dietary supplements is becoming increasingly common, especially in the U.S., selling at very affordable prices and in multiple outlets. In Europe, although less frequent, estimates point to an expense of 1,500 million euros in these products. Despite a rising world market, experts warn that many supplements are unnecessary and even, in some cases, dangerous. Read the rest of this entry »

High doses of this mineral may cause undesirable effects on health

Selenium is an essential micronutrient for humans, why should be present in the diet. However, to fulfill the roles that are involved in the body, are sufficient small doses (dietary reference intakes for adults are at 55 micrograms/day). Moreover, in large amounts can be toxic.

Although the selenium content is variable depending on soil cultivation, the main dietary sources are nuts, fish, whole grains (bread, pasta, rice), wheat germ and sunflower seeds. In recent years, has been assigned a preventive role against various diseases, especially for some types of cancer, including prostate and stomach cancer. Thus, supplementation with this element is, in some areas, habitual. Read the rest of this entry »

This article describes general information mesothelioma, because this disease prognosis mesothelioma is difficult to assess because there is always a great variability in time before diagnosis and the rate of disease progression. In a large retrospective series of pleural mesothelioma patients an important prognostic factor of stage, age, functional status, and histology.

Various surgical procedures May be some patients and provide long-term survival without cure. In patients treated with aggressive surgical methods, are factors associated with better long-term survival of epithelial histology, negative nodes and negative surgical margins. In patients with aggressive surgical approach to treat the status of the lymph nodes is an important prognostic factor.

The median survival was reported in 16 months in patients with malignant pleural disease and 5 months in patients with extensive disease. In some cases, the tumor grows through the diaphragm, so that the site is the source of evil to judge. A cautious interpretation of results of treatment of this disease is due to differences in the choice between sets is essential.

A leak once the pleura and peritoneum, severe symptoms for at least 66% of patients. (See the PDQ reported on cardiovascular syndromes for more information.) A history of asbestos in about 70% to 80% of mesothelioma cases.

One study showed that eating tomato paste each day increases by 30% the level of skin protection against the sun. Consuming this food also increases significantly the levels of collagen, another crucial factor in maintaining the integrity of your skin.

The peppers contain a chemical called capsaicin, which gives them a taste spicy. In cancer cells of the skin, it induces a state of apoptosis, a process also known as programmed cell death. In short, peppers (especially the more spicy) push cancer cells to commit suicide. So if you like spicy food, you’re lucky. If you do not like spicy food at all and cannot stand the peppers, you can learn to love the spices and then the cancer cells of the skin will be very difficult to grow.

Another study focused on the fact that certain vegetables, like onions and broccoli, may prevent skin cancer.

Before the skin cancer, all foods are not equal. Some foods help to better prevent skin cancer than others.

Some foods may slow the development of some cancers and prevent or combat skin cancer. For example, fruits and vegetables and whole grains have been known for natural ability to prevent and fight against skin cancer. Because of their phytochemical composition, these types of foods better protect the body against cancer in general and against skin cancer in particular.

Foods low in fat and those that are rich in fiber is best to ward off skin cancer. Since dietary fiber is disturbed bowel faster, carcinogenic toxins cannot accumulate or be stored too long in the vital organs. Eat these foods regularly will help to prevent skin cancer.

Colon cancer: screening too often neglected

A study in Britain showed that colonoscopies control after removal of intestinal polyps are frequently inadequate and untimely made.

According to a study published in Oncology in on the 581 patients who underwent colonoscopy with removal of polyps, the authors believe that the recommendations of the HAS are not respected, as a result of patients and physicians.

Yet they had a high risk of cancer with a protruding polyp with a diameter greater than 10 mm and this polyp had already passed the stage of adenoma. Read the rest of this entry »

Focal therapy: new treatment against prostate cancer

While the debate among health professionals on screening for prostate cancer is still not settled, several new strategies against prostate cancer are currently being tested in particular to avoid the effects of conventional treatments.

Currently, patients have two options:

1. They can be actively monitored, not always lived psychologically
2. Or active treatment to cure, with a significant risk of urinary squeal and or sexual.

A screening service that makes you really

Colorectal cancer is responsible each year in France for 17,000 deaths per 37 000 new cases. This is the third most common cancer in terms of frequency, the second for mortality.
If the treatments have greatly increased, their effectiveness depends largely on early diagnosis of these tumors. But still 40% of these diagnoses are made when there are already metastases.

I insist a little on the subject at this time because the Inca and the Ministry of Health jointly launched a campaign to encourage people aged 50-74 to get tested.

Some reminders about this cancer:

* Tobacco, alcohol, obesity, physical inactivity and high-calorie diet rich in meat promote the occurrence of this cancer. Read the rest of this entry »

Dr. Karas was not only responsible to clarify that the cause is still unknown point in the relationship between “good” cholesterol or HDL and oncological diseases, but also the concerns about drugs should not be taken as specific recommendations .

“HDL is supposed to affect the likelihood of developing cancer or not more so because it does work for assistance with the immune system, helping to find and destroy abnormal cells,” concluded Dr. Richard Karas.

For his part, Dr. Eduardo Esteban, cardiologist, executive committee member of the Heart Foundation Argentina, accessed locally by Pro-Health News said that “beyond that is important to keep your HDL levels raised by scientists Americans, the main work of one person must be kept under your LDL or bad cholesterol, a condition that is achieved by implementing many of the measures mentioned above and habits. ”

“This means that of course have the higher good cholesterol is very good, but most of all have to work on reducing the bad which is what brings more complications,” added Dr. Stephen.

After having shown that people with high levels of LDL or ‘bad’ had a greater chance of developing cancer, a group of researchers concluded that having high cholesterol “good”, ie the HDL (high density lipoprotein) helps to reduce the risk of development of oncological diseases.

The team of Dr. Richard Karas of the Molecular Cardiology Research Institute at Tufts University in Boston, United States, analyzed 24 studies involving a total of 76 000 people under treatment with statins and 70 000 who were taking placebo.

“The higher the HDL the better the quality of life of the person,” said Dr. Karas in the Journal of the American College of Cardiology.

From experience, the team led by Karas was found that with increasing the level of HDL is a risk of developing any cancer decreased. In this regard, they noted that “physicians should try to ensure that their patients have a good cholesterol 40mg/dL above for men and above 50 mg / dL for women.”
