Diagnosis by ... sniffing

Finally, yellow fever can make sick people radiating the smell of meat shops, also sick colon music-an infection in the lymph nodes-causes patients to have the smell of beer thiu always.

Even the patient also claimed that can "smell" the smell of her own cancer. According to Ms. Joanie, a member of the Forum network, said that when her husband's prostate cancer, and lung cancer when she was, she could smell the ' rotten ", the smell disappears when the cancer is treated.

According to Dr. George Preti, in Mr. Monell Chemical Senses Center in Philadelphia, United States of America said that he had heard many patients since that they smell odors in humans with cancer. He hoped that this discovery could help find new ways to diagnosis cancer sooner, especially with ovarian cancer, the disease is usually diagnosed only when it was too late.

New one week ago, researchers at the Karolinska Institute, Sweden, have discovered that we can smell the smell of people that the immune system is active. This smell appeared just hours after exposure to the bacteria.
