How to Stay Healthy

Here are some common-sense principles for staying healthy.

Eat Well

Fill your plate with a colorful variety of fresh fruits and vegetables.  These are low calorie foods filled with vitamins, minerals, fiber, and antioxidants.  Avoid red and processed meat.  Eat a greater amount of protein-rich foods such as seafood, eggs, beans, peas, soy products, nuts and seeds, and lean meats such as poultry.  Decrease your intake of refined sugars. Eating this way will increase your energy and lower your risk of heart disease, diabetes, and certain cancers.

Exercise Often

Aim for at least 30 minutes of continuous aerobic exercise everyday.  This will increase your energy, help you manage stress, improve your sleep, and lower your risk of developing heart disease, dementia, and mood disorders.

Prioritize your relationships with friends and family

In our fast-paced world in which there is always more to do, it is easy to neglect spending time with our loved ones.  But a wealth of scientific research shows that people are most fulfilled when they are engaged in deep, nurturing relationships.  Conversely, chronic loneliness has toxic health effects.  A fascinating article linked here speaks to this point.   So make time for your most important relationships, even if that sometimes means being less productive.

Don’t Smoke

Smoking markedly increases your risk of coronary artery disease, chronic obstructive pulmonary disease, and cancers of the oropharynx, lung, and bladder.

Get Your Regular Check-Ups

Check with your doctor to get your blood pressure and cholesterol measured and to make sure you are up to date on health maintenance measures such as vaccines and cancer screening.

Should You Get Screened for Prostate Cancer?

PROSTATE_CANCER

Part of my annual physicals with patients is reviewing a health maintenance checklist.  I verify that they are up-to date with age-appropriate vaccines, cancer screening tests, and other preventative measures.  For men over age 50, we discuss whether to screen for prostate cancer.  At first, it may seem like a no-brainer to screen for any kind of cancer.  But with prostate cancer, the decision whether or not to screen is not so straightforward.  In this post, I’ll provide some basic information about prostate cancer that I hope will be helpful.

What is the prostate?

It is a gland that sits below the bladder and in front of the rectum.  It forms a ring around the urethra, the tube takes urine out of the body.   The prostate gland’s function is to secrete fluid that takes sperm out of the body.

What is prostate cancer?

In prostate cancer, the cells of the prostate become abnormal and grow out of control.  Prostate cancer can spread to other parts of the body and ultimately cause death.

When should I be concerned that I might have prostate cancer?

It becomes more common as men age, most prevalent in men over age 50. Some symptoms of prostate cancer are needing to urinate more frequently and having a urine stream that is slower than usual.  However, these symptoms can be from other health conditions such as having an enlarged prostate.

How do doctors test for prostate cancer.

There are two initial tests. The first is the rectal exam in which the doctor puts their finger in the rectum and presses on the rectal wall to feel for abnormal areas on the prostate. The second is the PSA blood test. PSA can be high for other reasons besides prostate cancer.  For example, having a big prostate, having a prostate infection, and having recently had sex can all make the PSA high.  So if the PSA is high, it is usually repeated to see if it stays high.

If the PSA or rectal exam suggests cancer, what comes next?

Usually a urologist performs a biopsy of the prostate in which they get tissue from the prostate to be examined under the microscope.

What are reasons why I should get screened for prostate cancer?

One large European study showed that after 9 years, men who had done PSA testing had a 20% lower chance of dying of prostate cancer.  34,000 men die each year of prostate cancer and it can be a painful death.  It is second only to lung cancer in causing cancer-related deaths in men.  For men with aggressive prostate cancer, the best way of curing it and preventing death is catching it early by doing the PSA test.  If prostate cancer is caught early, the cure rate is nearly 100%

So why wouldn’t you want to get tested for prostate cancer?

Many prostate cancers detected with screening are unlikely to cause death.  These cancers would never have spread beyond the prostate and have harmed the man.  One European trial says that you have to treat 50 men with prostate cancer that was never going to bother them in order to prevent one death from prostate cancer.  Treating non-aggressive prostate cancers can cause frequently serious problems like impotence and incontinence.  In fact, roughly half of all men who receive radiation or surgery have incontinence and impotence.  So many men are receiving a harmful treatment for little benefit.

Once a prostate biopsy is done, can doctors predict if they prostate cancer will be aggressive and life-threatening?

The PSA score, the way the prostate cancer looks under the microscope (Gleason score), and how far is has spread help predict how threatening the cancer will be.

Bottom Line

Men must weight the potential benefits of screening against the potential harms.  One strategy is to screen for prostate cancer only in men with an increased risk of aggressive prostate cancer, such as men of African ancestry and those with a family history of prostate cancer.  Another approach is to broadly screen for prostate cancer, but closely monitor, rather than treat men with prostate cancer that is not aggressive.  In my conversations with patients, we discuss the pros and cons of prostate cancer screening and do our best to arrive at a decision together.
