People with Down syndrome may hold the key to the initiation of new studies and research to assist the treatment of cancer patients .

Until recently, experts on the subject did not have an accurate answer to why people with Down syndrome were not affected much by the cancer , except in a few cases.

Recently, scientists at Children’s Hospital in Boston found that the same factor that produces Down syndrome prevents tumors continue to develop, we are referring to a copy of chromosome 21.

Most people have two copies (one from each parent) of the 23 chromosomes that include genetic information of each of us. In the case of people with Down syndrome on chromosome 21 have one more, so that instead of having 2 have 3.

In studies with mice, they concluded that the mere presence of the extra chromosome significantly help to prevent them from growing tumors.

The discovery opens the door to a new treatment that may mean in the future an important aid for cancer patients .

The increase in cases of kidney cancer has doubled the rate of 7 per 100,000 inhabitants in 1975 to 12/100.000 today.

This increase has been determined especially among women who smoke increase the chances of tumor risk by 35 percent.

The information has been offered in the 34 th National Congress of the Spanish Association of Urology (EAU) at Feria Valencia, adding further data related to the increase in victims of cancer as a result of changing lifestyles, poor diet and inactivity.

The determinants of tumors respond to a hereditary component , so that affects men and women having twice the incidence in males. However, women have increased in number as a result of smoking.

The detection of these tumors but today it is more accurate with new imaging techniques.

The annual increase is caused in turn by the best diagnoses currently offered and an increase in tumors in younger people as a result of smoking, for example.

However undeniable is that the removal of tumors early can turn in a better appreciation of life.

Without doubt, the heart is one of the organs most commonly affected our lives in general, do not forget that among the leading causes of death worldwide, heart disease are at the top.

Primary heart tumors are rare, however cardiac metastases are seen in about 5% of patients who die from cancer.

Among the most common primary tumors are the myxoma, which is the most common and is usually located in the atria, but you can stay at any of the four chambers.

We can also find lipomas, fibromas, rhabdomyomas and sarcomas. Among the most frequent, the five that top the list are benign, and together account for 80-90% of all primary tumors of the heart.

Treatments

Surgery: invasive technique to remove the tumor. Usually also extracted tissue surrounding the tumor, to prevent metastasis.

Radiation therapy: high-energy rays are used to damage cancer cells, thereby halting its growth and division.

Chemotherapy is drug treatment, which involves the injection of drugs that attack cancer cells in blood vessels or muscles. Chemotherapy is usually given in cycles, ie, after a treatment period is a recovery.

The snuff smoking is the main cause in 90% of cases of lung cancer in both men and women. Decades ago, this tumor was much less common in women and it was featured it was more likely that was not related to snuff. These differences are disappearing rapidly, reflecting the incorporation of women with smoking in the previous years.

Another part of this type of cancer is caused by inhaled substances and who are in the workplace, a phenomenon related to the 10% -15% of lung cancer in males and 5% in women. The most important of these substances are asbestos, such as those used in asbestos factories.

Lung cancer can also be caused by radiation received at the chest, such as treatment with radiation therapy used to treat breast cancer and lymphoma. The interval between radiation exposure and cancer onset is usually very long, around age 20. The greatest risk are people who tried for many years with old appliances, and smoked during the following years. The risk with modern radiotherapy equipment is very low.

Hereditary factors have little relation to lung cancer.
