Each person has his or her own odor（氣味），which can even be used to tell if a person is healthy，reported HowStuffworks，a famous website from America.
Diabetes（糖尿?。琭or example，can make a person's body smell like bad apples.Yellow fever smells like a meat shop and lung（肺） disease causes the breath to smell fishy.
These smells are all the results of diseased cells（病變的細(xì)胞）.A diseased cell gives off different chemicals（化學(xué)物）.And these chemicals do harm to a healthy cell.As the healthy cell changes，so do the body's smells.
The smells of disease aren't a new discovery.The real news is how powerful this sense of smell is when it comes to smelling out disease.
For example，a woman in Scotland noticed her husband's body odor was changing as his Parkinson's disease（帕金森病） got worse.Scientists at Edinburgh University put her nose to the test，asking her to tell whether a group of people had Parkinson's.As a result，she found that in this group of people，12 of them were had the disease.And she was right.
If some people can do such an amazing job of discovering disease through smells，just think what dogs can do.A dog's sense of smell can be much better than a human's.
In fact，dogs can do an amazing job——telling whether a person has prostate cancer（前列腺癌）.Several studies found that they were even able to tell prostate cancer from other types of cancer.It's so unbelievable!
