Symptoms

At the beginning, the prostate cancer does not cause any symptom. Note that those listed below may be related to another prostate disease, such as benign prostatic hypertrophy.

• Difficulty urinating : difficulty starting to pass or holding urine, inability to pass urine, a need to pass urine frequently (especially at night), poor urine output, a burning sensation or pain when passing urine.
• Du blood in urine or semen.
• pain or frequent stiffness in the lower back, hips or upper thighs.
• Changes in urinary function: frequent urge, urge to urinate, urge to push, urine retention, burning while urinating.
• Changes in the genitals: painful ejaculations, or difficulty getting an erection. Predisposed people 

Note that some men ” at risk Will never get prostate cancer. Several risk factors are being studied.

• Age. In North America, prostate cancer mainly affects men over the age of 60. The average age at the time of diagnostic is 70 years old, and 80 years old at the time of death. Younger, only 0,5% of prostate cancers appear before age 50, and 22% between 55 and 64 …
• Family history. risks are higher when the father or a brother has already suffered from this disease, which suggests a predisposition genetic. This hypothesis is reinforced by the discovery that carriers of the BRCA1 and BRCA2 genes have an increased risk of prostate cancer.
• Ethnicity. Men of African descent are more at risk than Caucasians, who are more at risk than Asians. It is estimated that Indians and Chinese are about 50 times less affected by the prostate cancer than Westerners43. However, when they migrate to countries where the disease is more common, their risk also increases. This suggests that factors not only linked to genes, but also tofood exert influence.
• Obesity: a significantly overweight man has a higher risk of getting advanced prostate cancer.
• Inflammation or infection of the prostate increases the risk of prostate cancer, when it lasts a long time.
• Tall men have a higher risk of prostate cancer.
• Men who have been exposed to pesticides have a slightly higher risk of prostate cancer, especially if they have a history of prostate cancer in their family.
• Exposure to cadmium or rubber derivatives in the workplace also increases the risk of prostate cancer.

Risk factors

• High fat diet (processed meats and red meats). It has been known for several years that a diet comprising a large quantity of foods rich in gras (lipids) is associated with an increased risk of cancer of prostate3,4. However, it was not known what type of fat should be monitored. The animal fats contained in the Red meat were first pointed out in epidemiological studies5,6. However, the most recent study (2009) found that heavy eaters of processed meats (cold meats, bacon, sausages) are the most at risk of prostate cancer46. Large consumers of red meats would also be, but to a lesser extent. Read our news Processed meats would increase the risk of prostate cancer on this subject. Further studies are in progress.
• Smoking. There is no certainty about the influence of smoking on the incidence of prostate cancer. In contrast, a recent study shows that smokers with prostate cancer have a mortality higher 14.

Experts suspected the following factors to slightly increase the risk of prostate cancer. However, according to current data, they would not have no influence on the appearance of this cancer 42:

– Vasectomy (surgery performed for contraceptive purposes to make a man infertile)

– Alcohol consumption

– Frequency of ejaculations

– Benign prostatic hyperplasia

Remark

The results of some epidemiological studies had suggested a link between the consumption of dairy products and prostate cancer7,8. However, the results of a recent meta-analysis of 45 observational studies show that neither the consumption of dairy products in general nor that of milk is linked to an increased risk of this condition. cancer41.
