A new mobile phone application that spots cancer and is more accurate than the techniques routinely used in hospitals has been developed by scientists.
Pancreatic Cancer - All About the Disease, its Diagnosis and Management
Pancreatic cancer often involves its exocrine part. It grows aggressively, and often detected late. Treatment options include surgery, radiation and chemotherapy.

The U.S. researchers said the gadget could 'transform cancer care' by also making it easier for doctors to track how well drugs are fighting the disease in a patient's body.
In initial tests, it was 88 per cent accurate in distinguishing cancerous stomach tumours from benign growths.
Oral Cancer | Mouth Cancer - Types, Causes, Symptoms, Diagnosis, Treatment & Prevention
Oral cancer is a cancer that develops in any part of the mouth. It is more common in men over 40.

This compares with an average accurate of 84 per cent for the gold standard technique, which involves using chemicals that stain cancerous cells and show up under a microscope.

The tiny amount of tissue needed - one thousandth of a millilitre ould also spare patients the pain and risk of having repeatedly having pieces of their growth cut away for testing.

The device, developed at Massachusetts General Hospital in Boston, consists of a smartphone connected to a miniature MRI machine.
In tests, patients with suspected stomach cancer had tiny samples of their growths removed using a fine needle.
The researchers then added in antibodies designed to bind to proteins found in stomach tumours and tiny magnetic particles designed to latch onto the antibodies.
They then used the magnet in the hand-held MRI machine to excite the molecules in the sample, making them vibrate. The more the molecules vibrate, the more likely the sample is cancerous.
An app - or application - on a smartphone computes the results and provides doctors with a read-out.
The app has been described in the journal Science Translational edicine.
