There are over 100 types of Cancer
Over 7 million deaths a year (2004)
Makes up over 13% of the world’s deaths each year
The disease can affect all parts of the body

The top five in Men: Lung Stomach Liver Colorectal Oesophagus
The top five in Women: Breast Lung Stomach Colorectal Cervical

Tests are called screenings Different types:
Physical Exam Laboratory Tests Imagining Procedures Genetic Tests
Finding Cancer early can save lives

Circulating tumor cells About 90% of cancer related deaths are
not due to the original site of the cancer Important to find these traveling
cancerous cells Usually only several cells per 1-milliliter
sample of blood, which can contain tens of billions of normal blood cells

Blood is taken from the patient Passed over thousands of silicon “posts” Antibodies coat the outside of silicon Not too efficient given the amount of cells Scientists look for more efficient strategy

About 8 times more efficient
10 billion to 100 billion carbon nanotubes per square centimeter
Less than 1% carbon and 99% air
Easy to flow through

Can change the Geometry Tumor cells, about a micron in diameter,
down to viruses, which are only 40 nm Possibly able to test for HIV Leads are forming for handheld devices Lead to more availability Better diagnostics Location?
