• They grow and replicate slower than normal cells

• They are resistant to all forms of treatment

• They grow out of control and form clusters

Why is cancer difficult to study?

• It is a single disease with a simple cause

• It involves many different DNA variants and varies from person to person

• It only affects one organ in the body

• It has no known treatments

What is the current trend in cancer survival rates?

• They are unpredictable and vary greatly

• They are increasing as more treatments are found

• They remain unchanged over the years

• They are decreasing due to lack of research
