There are
several types of cancer that occur on the eyelids. The most
common variety (90-95% of eyelid cancers) is basal cell carcinoma,
which arises from eyelid skin. Squamous cell carcinoma also grows
from eyelid skin, while sebaceous cell carcinoma is a rare cancer of
the eyelid oil glands. Melanoma is a cancer of the pigmented
cells in the skin. In general, the risk that an eyelid lesion is
cancerous increases with a history of heavy sun exposure, previous skin
cancers, previous radiation, smoking, or a fair complexion.
Benign eyelid lesions, of which there are many types, can be
cosmetically unsightly or irritating but pose less risk to the
patients's health. Some of these are precancerous, however over
time they can develop into cancer.
You may see
a growth on your eyelid. Symptoms suggesting that a growth is
cancerous include slow, painless growth, bleeding and crushing of the
lesion, color changes, a pearly appearance, changes in the shape of the
eyelid margin, loss of eyelashes, and abnormal blood vessels on the
lesion.
Your eye doctor will examine your eyelid lesion and decide if there is a risk that it is cancerous.
Many eyelid
growths are not preventable, but you can reduce your risk of developing
some (especially many of the cancerous types) by avoiding excessive
exposure to the sun and smoking.
You can see
your ophthalmologist for any eyelid lesion that bothers you, but it is
especially important to be examined promptly if the lesion is growing,
bleeding, crusting, distorting the eyelid, changing color, or causing
loss of eyelashes. These signs may suggest that a lesion is
cancerous.
When your
doctor examines your eyelid lesion, he or she will decide if cancer is
suspected. If the lesion appears small and benign, it can usually
be removed in the office. You may require stitches and antibiotic
ointment while it heals. If your ophthalmologist suspects an
eyelid cancer, he or she will take a sample of the lesion and send it
to the lab to determine whether cancer is present and, if so, whether
the edges of the sample are cancer-free. If the lesion is large
or if the edges of the sample still contain cancer, more of the lesion
will have to be removed. Removing large cancers can leave large
defects in the eyelid, and in some ocases reconstructive surgery
performed by a specially trained ophthalmologist or plastic surgeon may
be necessary.
Many eyelid
growths, both cancerous and benign, are easily treated by removing them
surgically. Larger or deeper growths may be more difficult to
remove because of the defects left where the lesions were.
Fortunately, basal cell carcinoma, the most common eyelid cancer,
rarely spreads to other areas of the body. Other rarer types of
eyelid cancer may behave more aggressively and sometimes require
chemotherapy or radiation in addition to surgery.
Many
growths occur on the eyelids, and these growths can be divided into
those that are cancerous (about 15-20% of eyelid growths) and those
that are non cancerous, or benign (80-85% of eyelid growths).
Most of these growths come from the skin of the eyelid itself. It
is important to recognize cancerous eyelid growths so they can be
removed, just as skin cancers on other parts of the body should be
removed, while benign eyelid growths are generally not harmful.
