There’s no shortage of medical information on the internet; so, when it comes to men and prostate cancer, how do you separate myth from fact? What about dated and current information?

Other than skin cancer, prostate cancer is the most common cancer among American men, according to the American Cancer Society (ACS). The ACS estimates that in 2020 there will be about 192,000 new cases of prostate cancer in the U.S and about 33,000 deaths. About one in nine men will be diagnosed with prostate cancer during their lifetimes.

It’s time to hop off the internet, learn the positives about getting screened and how it can help prevent cancer.

Taking charge

Older men and African American men are more likely to develop prostate cancer, but there are many other risk factors to consider including family history, physical health, lifestyle and geographic location, according to the Prostate Cancer Foundation.

While 65% of cases are diagnosed in men who are 65 or older, 35% of men are diagnosed at an earlier age, according to the PCF. The average age at diagnosis is about 66, according to the ACS.

“Whether a man should be screened for prostate cancer is one of the most controversial issues he may face when visiting a doctor,” says Dr. Michael Herman, director of urology at Mount Sinai’s South Nassau Center for Urology & Urogynecology in Rockville Centre, New York. “There are pros and cons to screening, and there is quite a bit of debate.”

There is no right or wrong answer about when to start screening for prostate cancer, Herman says.

“The most important thing is for men to get informed and talk to their doctors about getting screened. Taking charge of their health is the best thing a man can do for himself,” he says.

Checking up and checking off

Recommendations from the American Urological Association are to start PSA (Prostate Specific Antigen) screenings for men without risk factors at age 55 and end them at 69, says urologist Dr. Michael Tyler at Z Urology in Coral Springs, Florida.

“All men should be screened. However, studies show that there is an increased risk of prostate cancer in overweight and sedentary males,” Tyler says.

There are two components of prostate cancer screenings. A blood test, called the PSA, and a prostate exam, also known as a digital rectal exam. The latter allows the prostate to be evaluated for size, roughness and elasticity, says Amit Kumar, president and CEO at Anixa Biosciences, a biotechnology company headquartered in San Jose, California.

“No screening test is absolutely accurate, and false positives often result from PSA testing,” says Kumar, who’s also on the board of directors of the American Cancer Society. “While a screening has definitely reduced death rates from prostate cancer, many healthy men have been subjected to unnecessary procedures and overtreatment in false positives.”

Tyler says several factors may falsely elevate the PSA levels — which are unrelated to cancer — including recent sexual intercourse, infection and benign growths.

“The PSA is only used to gauge the risk that someone has prostate cancer, not as a direct detector of prostate cancer,” Tyler says.

Symptoms of prostate cancer include frequent urination — especially at night — weak stream, urgency, pain, blood in the urine, erectile dysfunction, and pain and swelling in the legs, Kumar says.

“These symptoms should prompt a visit to the doctor, as they are not always specific to prostate cancer,” he says. “While these other conditions may need to be treated, they do not mean a man has prostate cancer.”

Herman says the vast majority of men diagnosed with prostate cancer respond well to treatment, and the earlier the disease is caught, the better.

“That is why it’s so important for men to talk to their providers about screening for prostate cancer,” he says.
