What Not to Say to Someone With Cancer
Experts caution that when caring for someone with cancer, there are six things friends or family often say–in an attempt to be sympathetic, supportive, or encouraging — that can have just the opposite consequence: shutting down communication and making the person with cancer feel worse.
Psychiatrist Jeffrey Knajdl, director of psycho-oncology services at Creighton University in Omaha, Nebraska, points to these six common sayings to avoid, along with suggestions for what to say instead:
4. “We can beat this.”
In our rush to be supportive, it’s all too easy to fall back on such encouraging and inspirational messages. But they can give cancer patients a deep-seated feeling of failure. “I call this the Lance Armstrong syndrome, this idea that if you have the right fighting spirit you can overcome disease,” says Knajdl. “I admire Armstrong and he’s done great things to publicize cancer, but this idea that people can triumph over cancer with will power and an upbeat attitude is just crazy. There are all sorts of factors that contribute to why some people recover and some don’t. The truth is, some people just get lucky.”
