It’s horrible… Yes, the prostate cancer is horrible. You must know the symptoms and prevention of the prostate cancer.
What is the Prostate Cancer?
Prostate cancer is a disease that gets developed mainly in older men. As men age, the prostate may enlarge and block the urethra or bladder. This can cause difficulty urinating or interfering with sexual function.
The problem is known as benign prostatic hyperplasia, which often requires surgery to correct it. The symptoms of benign prostatic hyperplasia or other problems that affect the gland may be similar to the symptoms of prostate cancer.
Prostate cancer is the most frequent of all cancers among men.
What are the Risk Factors for the Prostate Cancer?
- Age: Age is the main risk factor for prostate cancer. The risk of developing prostate cancer begins to increase from 50 years of age in white men and from 40 years of age in black men or with a family history (father or brother) of prostate cancer. Almost two out of three cases of prostate cancer are detected in men older than 65 years.
- Race: Prostate cancer is more common in black men than in men of other races. In addition, black men are more likely to be diagnosed at an advanced stage, and are more than twice as likely to die of prostate cancer compared to white men. On the other hand, the lowest rate of prostate cancer is observed in individuals of Asian race.
- Family history: The risk of prostate cancer is strongly influenced by family history. Those men who have a first-degree relative (father or brother) diagnosed with prostate cancer are more likely to develop the disease. Only 5-10% of prostate cancers have a hereditary component.
In hereditary prostate cancer, the age of onset of cancer is earlier (before 55 years) and patients often have first-degree relatives with prostate cancer. Genes involved in increased susceptibility to the development of prostate cancer have been discovered.
- Diet: Recent studies suggest that high consumption of animal fats may increase the risk of prostate cancer.
On the other hand, supplements of vitamin E and selenium and high consumption of lycopene could have a protective effect in some prevention studies (see below).
- Obesity: Most studies have not found that obesity is associated with an increased risk of developing prostate cancer.
- Exercise: in most studies, exercise has not been shown to reduce the risk of prostate cancer.
- Alcohol: There does not seem to be a correlation between alcohol intake and the incidence of prostate cancer, although its high consumption increases the risk of more aggressive cancer.
- Coffee: High coffee consumption seems to be associated with a lower incidence of more advanced prostate cancer.
- Tobacco: Smoking has been associated with an increase in the incidence, as well as an increased risk of relapse after diagnosis.
- Infection and inflammation of the prostate: Some studies have suggested that prostatitis (inflammation of the prostate gland) may be associated with an increased risk of prostate cancer, although other studies have not found such an association.
Is it possible to prevent prostate cancer?
– Tomatoes (raw, cooked or tomato-containing products such as sauces) and watermelons are high in lycopene . These substances are antioxidants that help prevent DNA damage. Some preliminary studies suggest that lycopene may help reduce the risk of prostate cancer, although a more recent study found no association between lycopene blood levels and the risk of prostate cancer. The investigations on the subject continue.
– To study the possible effects of selenium and vitamin E on the risk of prostate cancer, several researchers conducted a study called Selenium and Vitamin E Cancer Prevention Trial (SELECT). In this clinical study, about 35,000 men were chosen at random to take one or both of these supplements or a placebo. After an average of five years of daily use, none of the supplements demonstrated a reduction in the risk of prostate cancer.
– Several studies are currently looking at the possible effects of soy derivatives (isoflavones) on the risk of prostate cancer, although it seems that their intake could reduce the incidence of prostate cancer.
– In a study that was conducted in men at high risk of developing prostate cancer, the administration of the drug Finasteride managed to reduce the risk of prostate cancer by 25% compared with a placebo.
However, this medication causes side effects such as decreased sex drive and impotence. On the other hand, it improves the urinary symptoms associated with prostatic hyperplasia. A higher rate of high-grade tumors (which have a worse prognosis) was also observed in the patients who took the drug in the study.
With all this, the use of this drug can not be recommended as a preventive agent. Other clinical studies are underway with other drugs that may play a role in the prevention of prostate cancer.
