An important progress in the development of vaccines researchers performed genetic University of Leeds, UK, and the Mayo Clinic in Rochester, United States.

This is the use of a virus containing DNA fragments that are the cause of prostate cancer, which when injected in the blood of diseased mice produce large amounts of antibodies that end up destroying the tumor. The encouraging results are published in the latest edition of Nature Medicine.

Until now, researchers feared that a vaccine with several genes could cause a real explosion immune system, which could get out of control and cause death.

So they were surprised to see that the current vaccine works smoothly and has the desired effects are to destroy malignant cells. Read the rest of this entry »

Yes, more and more. For example, in U.S. prostate cancer has overtaken lung cancer and colon and has become the most common cancer in males. In Spain, it is also one of the most common and important of the male population.

To what age is becoming more relevant?
usually is exceptional detect prostate cancer below 40 years and remains very rare in men aged 50 years. From that age will increase the number of diagnosed cases. In the eighth decade of life is where most cases are diagnosed.

Is it true that if all men lived to age 100 would have prostate cancer?
Just about. Prostate cancer is most often diagnosed at autopsy in many men who have died for other reasons. This means that cancer is “microscopic”, ie they can only be evaluated through a study of prostate tissue and clinical cancer is one that gives symptoms. Not all cancers are discovered microscopic because before the patient dies of other causes.

Is it the same prostate cancer who “suffer from prostate” or benign prostatic hyperplasia?
Not at all. Benign prostatic hyperplasia is also a process linked to aging and tends to compress the urethra making it difficult emptying of urine from the bladder to produce a constellation of symptoms known as prostatism: difficulty in starting urination, getting up at night to urinate … whereas prostate cancer often produces no compression of the urethra, but that starts at the outside of the prostate. Another key difference is that BPH is not cancer and therefore does not produce the death of the patient while the prostate cancer depending on its stage, and other factors may be the cause of death.

Prostate cancer is a silent disease. The tumors arise and grow without the patient notice that something is wrong. Symptoms appear when the cancer is in advanced stage and when, probably exceeded the prostate and invade other organs. Early diagnosis is only possible with annual checkups that include digital rectal examination and blood test to measure PSA level. According to Elias Mora said Kumdoz (www.dreliasmorakumboz.blogspot.com), urologist and former Chief Metropolitan Polyclinic of Urology Cancer Hospital Padre Machado, the symptoms of advanced prostate cancer are often similar to those of BPH, which is the overgrowth of the prostate decreased in strength urination and need to urinate several times each night, mostly.

But sometimes they also have other symptoms as blood in urine, weight loss, fatigue, anemia and frequent fractures, if the cancer has spread to the bones. “As for the prognosis, medical science has made ??great progress. All patients who were diagnosed with prostate cancer at an early stage can be cured, if nature is not very aggressive, “said Mora. The burden of aggressiveness of the tumor depends on the genetic and biological potential. In the case of prostate cancer, this feature is still difficult to detect. “Survival depends on the biological potential of the tumor but can only presume pathologically” he says. Sometimes, when the cancer is advanced, androgen blockade is attempted to prevent further growing. “The tumors have cells that rely on testosterone to grow.

If you block the male hormone, sometimes the patient survives. But there are other cells that are not dependent on testosterone, the hormone-blocking is not always effective even when This principle itself is an improvement, “says Mora. There are only two ways to cause blocking hormonal drugs or with surgery to remove the testicles. Mora explained that a high level of PSA in the blood does not always mean cancer. “The antigen reveals prostate disease, which need not malignant but can be an infection or inflammation,” he explains. The first treatment a patient receives an upturn in its antigen is antibiotics. If they remain high, should be biopsied. In its infancy, it is recommended the removal of the tumor, usually by removing the entire prostate.

This can be done with traditional surgery, laparoscopic or robot. If the cancer has not spread, the nerves can be preserved, allowing the patient regain erectile function and urination. “Any of the three forms of surgery guarantee the same results. What is important to reduce the risk of future incontinence or erectile dysfunction, is the physician’s experience. The more transactions you have made, there is less risk of nerve damage, “he says.

Prostate cancer (the most common form is adenocarcinoma) is the malignant growth of prostate gland cells produced in the prostate gland. These cells multiply and may spread beyond the prostate gland. The prostate gland, which is about the size of a walnut, is located between the bladder and rectum of the male pelvis. One of the key functions of the prostate gland is to provide the nutrients you need sperm to mature sperm. The prostate secretes fluid that also help protect the sperm on their journey through the female reproductive system.

Prevalence
More than 70% of all prostate cancer cases diagnosed in the U.S. affect men over 65 years. The incidence of prostate cancer among African Americans and Jamaican origin is more than twice that among whites (70.4 / 100,000, compared to 28.8 / 100,000). This disease is common in North America and northwestern Europe, and considerably less common in Asia and South America (13.0 / 100,000 and 23.5 / 100,000, compared to 28.8 / 100,000). (American Cancer Society, Cancer Facts and Figures 2005 , pg. 18). Recent studies indicate that genetic genetic predisposition may be the cause of 5-10% of prostate cancers. Data from the Study of the Cancer Prevention II and published in the journal European Urology * indicate that dietary habits also influence the development of the disease. Because of this relationship between nutrition, physical activity and cancer, American Cancer Society published in 2002 updated guidelines for nutrition and physical activity.

Screening
digital rectal examination (DRE) and blood tests to measure prostate specific antigen (PSA) are the two most common screening measures to detect prostate cancer.

Advances in the diagnosis of prostate cancer
British scientists are testing a genetic test that, they say, could detect which patients with prostate cancer need aggressive treatment.

Preliminary clinical trials show that men with high levels of genes responsible for cell cycle progression (CCP) have the more serious tumors.

CCP test could also potentially prevent many men with milder forms of the disease are subjected to unnecessary aggressive treatment.

As the scientists in the journal Lancet Oncology, will now be necessary to conduct larger clinical trials.

Anxiety and risk
Prostate cancer is one of the most common cancers in men. Only in the UK are diagnosed about 37,000 new cases of the disease each year.

Currently, physicians face many difficulties to predict how aggressive prostate tumors are because the available tests and examinations are sketchy.

It’s really encouraging that this may also apply to prostate cancer, with which we desperately need a way to predict how aggressive the disease is

For example, one of the tests currently used, the prostate-specific antigen (PSA), may yield results “worrying” even if a tumor is present. Read the rest of this entry »

The prostate is a gland in the male reproductive system that produces some of the seminal fluid. Prostate cancer, age-related, is more common in men over 65 years. According to Alirio Salinas urologist in the United States is the most common cancer in men and Europe is second only to lung cancer.

Cancer can manifest in individuals with family history, genetically predisposed. These generated an alteration of the chromosomes that triggers the production of testosterone, male hormone that increases the risk of tumor formation. Another risk factor is the high-fat diet, one hypothesis suggests that influences the formation of cancer and Asian populations have a lower risk of prostate cancer, while the Anglo-Saxon living in the area have a higher risk due to consumption of foods rich in saturated fats is very high. Africans and South Americans would have a medium risk.

Prostate cancer has three stages and is curable only in the first two, when by means of digital rectal examination detected nodules located somewhere in the prostate. By further examination is required the level of antigen, a substance that is released from the prostate and circulating in minute quantities in the blood. Read the rest of this entry »

The indole-3-carbinol is also effective for prostate cancer, it does act in two ways: first blocks several phases of cancer cells and on the other inhibits the production of a protein specific to the prostate (PSA) ; high levels in the protein are indicative of cancer.

The consumption of broccoli along with the tomatoes enhances the effectiveness of this cruciferous against prostate cancer.
