As a patient, you're entitled to ask your health care providers anything. In that sense, there are no bad questions.

But some questions will help you get more out of your interaction with your health care providers than others. This advice comes from my experience as a medical oncologist and a cancer survivor.

Before asking your questions, remember that you're dealing with a human being. Doctors are not gods or saints. We try to remain professional, but just like anyone else, we prefer to deal with those who are pleasant.

You don't have to hide your anger, but anger that's not accompanied by constructive criticism can result in a very poor patient-health care provider relationship.

Next, you need to recognize that doctors don't have unlimited time. Yes, we'd like to provide you with as much time and attention as you need, but the reality is that the time one health care provider has for one patient is limited. In many cases, we must prioritize our time to address the needs of patients in the most critical medical situations.

So, well-timed, organized and well-thought-out questions can make all the difference.

Here are some things that you can do before you start asking questions:

• Ask if this is the best time to ask questions, and if not, ask when would be a better time. Doctors do appreciate this question.
• Prepare yourself ahead of time with an organized list of questions.

• "I don't understand what you're saying."

  If you don't understand, please say so. Also, don't nod your head if you don't understand. If you keep nodding, the doctor will assume that you understand and continue speaking.

• "Can you please explain that using simpler words?"

  Doctors have a tendency to use professional jargon, although we try not to. So, if you don't understand the term, ask for clarification. On the other hand, if the terminology seems too simple for you, ask for a more detailed explanation.

• "My understanding is X; do I understand this correctly?"

  It's important to restate what you've heard to confirm that you understand. "Did we agree to X, then Y, then Z?" This is a good thing to do at the end of your visit.

• "Am I going to die?"

  Nobody knows. Although you may be tempted to ask this, instead consider asking about how long symptoms/illness might last, when the tumor might shrink, or when you can go back home or to work. Although doctors generally cannot predict overall outcomes, they may be able to estimate these more concrete aspects.

• "What would you do if this were your wife or your husband?"

  Unless you are very familiar with the personal values of the health care provider, you can get misled into a decision that you may not be happy with later on.

• "I don't like (hate) clinical trials or chemotherapy."

  Be careful before you say this. Doctors may remember your words so strongly that they will never bring it up in the future. If you change your mind later, you should say so; you would be surprised how much we're influenced by what you say.

• Bad-mouthing other doctors versus providing constructive criticism.

  We are unsure of how to react, and we also wonder whether you will then bad-mouth us if you feel that we didn't do well. Constructive criticism can be useful, but simply expressing strong emotions doesn't help us.

• "I don't know what I should ask" or asking no questions.

  This is like saying you have no interest in what's happening. If you don't know what to say, we don't know where to start, either. If you honestly have no questions, at least state that you clearly understand the situation and the plan.
