Hello, everybody.
My name is Dr. Emma Short,
and I work as a
consultant pathologist
specialising in gastrointestinal
and soft tissue pathology.
The talk today will
explore colorectal cancer,
which is also known
as bowel cancer.

During the talk today,
we will look at the
epidemiology of bowel cancer,
the aetiology, or
causes, of bowel cancer,
and we'll consider the clinical
aspects of bowel cancer,
particularly how it may
present, how it's diagnosed,
and how it's managed
in clinical practice.
We will end by
discussing a case study.
Please note, the case study
describes a fictitious patient.

One of the reasons
why it's important
to be aware of bowel cancer
is because it's
extremely common.
Overall, bowel cancer is the
fourth most common cancer
in the UK,
and it's the second
most common cause
of cancer-related death.
If we look at females
and males separately,
we will see that it's the
third most common cancer,
second to breast
and lung in females
and prostate and lung in males.
Overall, bowel
cancer will affect
1 in 20 females
and 1 in 17 males.
The incidence of bowel cancer
increases as we get older.
The incidence rates
are highest in people
aged between 85 to
89 years of age,
but nearly half of
cases are diagnosed
in people aged 75 and over.
We find that there is a high
incidence of bowel cancer
in developed countries,
with a 20-fold
increased incidence
compared to developing
countries,
and this is thought to be due
to lifestyle differences,
particularly
differences in diet.
The prognosis of bowel cancer
is very much dependent
upon its stage,
so how extensive the disease is.
Overall, over 50% of people
diagnosed with bowel cancer
will live for at least ten years
following their
initial diagnosis.
