This week I’m going to take a break from talking to you about golf. I’m going to talk instead about something that could save your life.

Rule: If one day something is wrong with you and it doesn’t clear up by itself in two weeks, go to a doctor to begin a process of diagnosis.

Two years ago, in November 2014, I followed that rule, as I have done for many years. While diagnosing my complaint, an imaging study revealed a tumor.

By the sheerest bit of luck, not only in timing, but also in the location of the tumor, I was diagnosed with cancer at a very early stage. So far the treatments have been successful and my prognosis is good.

The doctors said the original complaint was nothing to worry about and it cleared itself up in six weeks. Had I waited it out, I would not have known about the cancer until it had become quite advanced.

I have talked to several cancer patients whose disease was also found by the merest accident.

There are many reasons why people don’t go to see a doctor. They are afraid of what might be found. They know what it might be and are afraid of the treatment. They don’t have time to be sick right now. I don’t go to doctors and I’m OK so far. And so on.

I can’t argue with these reasons because they are sincerely felt. All I can say is, go see the doctor anyway.

I’m not trying to be alarmist. The next time you feel something is off, it’s probably not anything big. But then it might be. You never know.

So you have two weeks. Then you go see the doctor. O.K.?
