Warning Signs
For Skin Cancer
Skin cancers
start as small bumps on the skin that slowly, or sometimes rapidly,
enlarge. These bumps are usually pain-free and commonly have been
present for a year or so. Skin cancers frequently undergo periods
of ulceration and bleeding followed by healing and then repeat this
cycle. A physician should examine any skin lesion that has a history
of bleeding.
Skin cancers
may have a variety of appearances. They may be flesh-colored, waxy
or pearly, red scaly patches, large tumor masses or sores that do
not heal. They may also undergo color changes such as red, white,
blue, black or brown. Your doctor should examine any skin lesion that
has an unexplained change in color.
Pre-malignant keratoses (actinic keratoses, solar keratoses,
or sun spots) are red, scaly lesions that occasionally give rise to
skin cancers. These lesions are due to sun damage and are commonly
found on the face, scalp, ears, neck, and hands. The presence of these
skin lesions is a warning sign that you have an increased risk of
developing skin cancer.
If
your doctor thinks that a skin growth is a cancer, a biopsy is performed
to obtain a diagnosis. The piece of removed skin is examined under
the microscope by a pathologist or dermatologist to determine if the
lesion is a skin cancer. If cancer is present in the biopsy sample,
the type of skin cancer is determined so that proper treatment can
be delivered |
