It bases its recommendations on the evidence of both the benefits and harms of the service and an assessment of the balance.

Clinicians should understand the evidence but individualize decision making to the specific patient or situation. Similarly, the USPSTF notes that ásványi fürdők prosztatitis and coverage decisions involve considerations in addition to the evidence of clinical benefits and harms.

Rationale Importance Prostate cancer is one of the most common types of cancer that affects men. The median age of death from prostate cancer is 80 years, and more than two-thirds of all men who die of prostate cancer are older than 75 years. An elevated PSA level may be caused by prostate cancer but can also be caused by other conditions, including an enlarged prostate benign prostatic hyperplasia and inflammation of the prostate prostatitis.

Men with a positive PSA test result may undergo a transrectal ultrasound-guided core-needle biopsy of the prostate to diagnose prostate cancer.

Benefits of Early Detection and Treatment The goal of screening for prostate cancer is to identify high-risk, localized prostate cancer that can be successfully treated, thereby preventing the morbidity and mortality associated with advanced or metastatic prostate cancer. Adequate evidence from randomized clinical trials RCTs shows that PSA-based screening programs in men aged 55 to 69 years may prevent approximately 1.

There is inadequate evidence to assess whether the benefits for African American men and men with a family history of prostate cancer aged 55 to 69 years are different than the benefits for the average-risk population. There is also inadequate evidence to assess whether there are benefits to starting screening in these high-risk groups before age 55 years.

Treatment by Cancer Type

Adequate evidence from RCTs is consistent with no benefit of PSA-based screening for prostate cancer on prostate cancer mortality in men 70 years and older.

Harms of Early Detection and Treatment The harms of screening for prostate cancer include harms from cancer de prostata prevencion pdf PSA screening test and subsequent harms from diagnosis and treatment.

Potential harms of screening include frequent false-positive results and psychological harms. The false-positive and complication rates from biopsy are higher in older men.

PSA-based screening for prostate cancer leads to the diagnosis of prostate cancer in some men whose cancer would never have become symptomatic during their lifetime. Treatment of these men results in harms and provides them with no benefit. Harms of prostate cancer treatment include erectile dysfunction, urinary incontinence, and bothersome bowel symptoms.

About 1 in 5 men who undergo radical prostatectomy develop long-term urinary incontinence requiring use of pads, and 2 in 3 men will experience long-term erectile dysfunction. More than half of men who receive radiation therapy experience long-term sexual erectile dysfunction and up to 1 in 6 men experience long-term bothersome bowel symptoms, including bowel urgency and fecal incontinence. Adequate evidence shows that the harms of screening in men older than 70 years are at least moderate and greater than in younger men because of increased risk of false-positive results, harms from diagnostic biopsy, and harms from treatment.

The USPSTF does not recommend screening for prostate cancer unless men express a preference for screening after being informed of and understanding the benefits and risks.

Epidemiology of Prostate Cancer

The decision about whether to be screened for prostate cancer requires that each man incorporate his own values about the potential benefits and harms.

The potential harms of screening, diagnostic procedures, and treatment occur soon after screening takes place. Although the potential benefits may occur any time after screening, they generally occur years after treatment, because progression from asymptomatic, screen-detected cancer to symptomatic, metastasized cancer or death if it occurs at all may take years or decades to occur.

How each man weighs specific benefits and harms will determine whether the overall net benefit is small.

The USPSTF concludes with moderate certainty that the potential benefits of PSA-based screening for prostate cancer in men 70 years and older do not outweigh the expected harms. Clinical Considerations Patient Population Under Consideration This recommendation applies to adult men in the general US population without symptoms or a previous diagnosis of prostate cancer.

Evitar los factores de riesgo y aumentar los factores de protección puede ayudar a prevenir el cáncer.

The sections below provide more information on how this recommendation applies to African American men and men with a family history of prostate cancer. Risk Assessment Older age, African American race, and family history of prostate cancer are the most important risk factors for the development of prostate cancer.

Other factors with weaker associations and less cancer de prostata prevencion pdf include diets high in fat and low in vegetable consumption. Cigarette smoking is associated with higher risk of prostate cancer mortality.

Screening PSA-based screening is the usual method of screening and has been studied in several large trials. Although new screening methods are being developed such as single- and adjusted-threshold testing and PSA velocity and doubling timeevidence is insufficient to support one method of PSA-based screening over another.

Evidence is also insufficient that using a prebiopsy risk calculator, with or without measurement of free PSA levels, or using genetic or adjunctive imaging tests meaningfully changes the potential benefits and harms of screening.

Cancer de prostata prevencion pdf is an important area of current research that has the potential to decrease the harms of PSA-based screening for prostate cancer. The use of digital rectal cancer de prostata prevencion pdf as a screening modality is not recommended because there is a lack of evidence on the benefits; digital rectal examination was either eliminated from or not included in the major screening trials.

These trials used varying screening intervals from 1-time screening to every 1 to 4 years and PSA thresholds 2.

The trial found no difference between groups in death from prostate cancer after almost 15 years of follow-up absolute risk, 4. The results varied across the individual ERSPC sites, and prostate cancer mortality was significantly reduced only at the sites in the Netherlands and Sweden. However, point estimates were in favor of screening at all sites except Switzerland. At the largest site Finlandthere was no significant benefit observed for prostate cancer mortality rate ratio, 0.

Although treatment is thought to be most immediately beneficial for men with high- and medium-risk prostate cancer, the vast majority of cases of screen-detected cancer are low risk. Among 5 ERSPC sites that reported the false-positive rate, approximately 1 in 6 men screened at least once had 1 or more false-positive results, and of the positive results in the first round of screening, two-thirds were false positives.

In Sweden, where a low PSA threshold 3.

The 3 large RCTs on screening predominantly included men aged 55 to 69 years. There is inadequate evidence longidase a prosztatitis kezelésében starting screening at a younger age in the average-risk population or to obtain a baseline PSA level. Evidence in men 70 years and older does not support routine screening because of the lack of trial evidence of benefit, the low likelihood of benefit given the time to realize benefit, and the increased risk of harms from false-positive results, biopsies, overdiagnosis, and treatment.

Although the evidence does not support routine screening in all men older than 70 years, the USPSTF recognizes the common use of PSA-based screening in practice today and understands that some older men will continue to request screening and some clinicians will continue to offer it.

Men older than 70 years who request screening should be aware of the reduced likelihood of benefit from screening and the increased risk of false-positive test results and complications of diagnosis and treatment.
