What
is cancer?
Cancer is the name given to a group of diseases that can occur
in any organ of the body. The body is made up of millions of cells.
Different body tissues have different types of cells, with different
functions, for example, bone, blood, muscle, skin. These cells
are constantly dividing to produce new cells to replace old ones.
Normally
cells divide in a controlled way. Sometimes this control is lost,
and the cells divide in an abnormal or uncontrolled way, and form
a tumour (growth or lump) or malignant disease, such as leukaemia.
A tumour may be malignant (cancerous), benign (non-cancerous)
or pre-cancerous (if left, may become cancerous).

What
is the difference between a malignant and a benign tumour?
back to top of page
Benign tumours are usually harmless and may not need any treatment.
They are quite common, and don't spread.
Malignant
tumours, or cancers, can spread to other parts of the body and stop
them working properly. Often this secondary spread is more dangerous
than the original cancer, which is why it is important to spot the
cancer as early as possible.

What
can you do to avoid cancer? back

It is important to remember that many cancers can be treated successfully
especially if they are found early. This is why screening programmes
have been set up for some common cancers, such as breast or cervical
cancer. For more information on screening click here.
It
is important that you get to know your own body, so that you are
aware of any changes that might indicate that you need to seek advice.
If symptoms carry on for 2 weeks or more, go and see your doctor
(GP). Often the GP will know by looking or feeling that there is
nothing to worry about, or may want to refer you to a hospital for
tests to make sure.
There
is no way of guaranteeing that you will never get cancer, but there
are things you can do to lower your risk. The European 10-point
code against cancer recommends that you...

cancers are also known to run in families. It may be helpful to find
out if there is a history of cancer in your family. If you are concerned
you should speak to your GP who may be able to organise screening
for you, or arrange for you to see a specialist who can offer advice
to people with a strong family history of cancer. |

If you are worried that you might have cancer, you should go and
see your family doctor (GP) as soon as possible. Your GP will then
decide whether you should be sent to see a doctor who specialises
in cancer.
The
Referral Guidelines for Suspected Cancer is a guide for doctors,
to help ensure that the patient is seen quickly if the doctor thinks
he or she may have cancer. Information about the guidelines can

Does
having cancer mean that you are going to die from it?
back to top of page
No. The chance of dying from the cancer will be different for each
individual, and will depend for example, on the type of cancer,
where it is, the stage it is at when it is discovered, and the person's
general health. Many cancers can be cured or controlled if they
are found early.
