Nowadays it is a common practice for some doctors and nurses to tell a lie to the patient who has got deadly disease.They try to hide the truth from the patient because they believe that the patient may suffer from severe mental trauma hearing the bad news.
But some others feel disclosing the truth is better.Then the patient can plan their last days better，and will be able to fulfill his last wishes and die peacefully.After all，the patient has the right to know his condition of disease.
In my opinion，whether or not we tell the patient the truth depends on different people and different situations.If the patient is afraid of death or is negative about life，doctors and nurses should hide the truth from him.On the contrary，if the patient is rational and positive，it is unnecessary to keep him in the dark and hide the truth intentionally.
