The reality is that a good suntan is a sign that
you are being exposed to too much UV radiation.
There are three main types of skin cancers. The
most dangerous of these cancers is melanoma. Early
detection of skin cancers is extremely important;
it can stop the spread of cancer to other parts
of the body.
The three main types of skin cancer are:
Basal cell carcinoma (BCC) - This is
the most common, but least dangerous type of skin
cancer. BCCs are usually found on the face and
neck. BCCs begin to form as small round or flattened
lumps which are either red, pale or pearly in
colour and may have blood vessels (which look
like tiny veins) over the surface. If untreated,
they will spread and can leave bad scarring if
you do not get early treatment.
Squamous cell carcinoma (SCC) - This
skin cancer is less common, but more dangerous
than BCC. This cancer can develop on the lips,
particularly the lower lip. SCCs are best described
as red scaling areas that may bleed and become
ulcerated. Very occasionally, SCCs may spread
to the lymph nodes.
Melanoma - This is the least common,
but most dangerous skin cancer. These usually
begin as a new spot, freckle or mole on the skin
that changes in colour, thickness or shape over
months. Melanomas sometimes develop in parts of
the body such as the eye and mouth. Melanomas
can be dark brown to black, red or blue-black
or a combination of colours. They can have an
irregular outline or shape. Melanomas can also
develop in pre-existing moles and people who have
a lot of moles seem to have a higher risk of developing
melanoma. Melanomas can spread to internal organs
and cause death if not detected and removed promptly.
Keratoses - sometimes called sunspots
- are dry, rough, firm spots on the skin and are
not skin cancers. However, they are early warning
signs of prolonged exposure to solar UV radiation.
Keratoses very occasionally develop into skin
It is the ultraviolet (UV) radiation in
sunlight which causes skin cancers. Even if you
are protected from direct
sunrays you may still be exposed to reflected
UV radiation. Natural surfaces such as snow, sand,
rock and water all reflect UV radiation, as do
some metallic surfaces, especially aluminium.
Exposure to solar UV radiation can still happen
on cloudy or winter days...
