askthedoctor Skin Cancer Facts Basal cell carcinoma is the most common type of skin cancer. Fortunately, in 95 percent of cases it can be cured — if it’s treated early. By Rear Adm. Joyce Johnson, D.O. E What to Keep an Eye Out For ■ If you have a sore that doesn’t heal, a bump that bleeds easily, a skin spot that changes, a waxy or pearl-like bump, or a bump with visible blood vessels, you should ask your doctor about basal cell skin cancer. ach year there are about a half million new cases of basal cell carcinoma, most in people 40 years and older. Basal cell carcinoma is often difﬁcult to recognize. It’s usually painless and not very noticeable, and it can manifest itself in many ways. It may be a small bump on the skin that is shiny and somewhat translucent or a bump that is ulcerated, oozing, and crusted. Sometimes the lesion looks like a ﬂat, reddened area, resembling a small scar. It also can be a slightly raised, irritated-looking area resembling psoriasis. In most cases — 90 percent — it occurs on parts of the body that are exposed to the sun, including the scalp. Basal cell carcinoma lesions can change slowly over time, generally over months or years. After several years of growth, a lesion could be less than an inch in diameter. It might begin as a shiny bump and gradually grow and develop visible, purple-reddish blood vessels. A lesion might be an oozing sore, then appear to heal, then ooze and crust again. These “healing” lesions can be the most dangerous, because even though they appear to be gone, they are still growing. Meanwhile, patients (and even physicians) who suspected a problem can forget about it when it appears to heal. When a lesion is suspicious, a biopsy is essential — it’s the only way to make an accurate diagnosis. A biopsy is usually quite simple and can be done quickly and easily in the doctor’s ofﬁce. After an injection of a local anesthetic, a small piece M AY 2 0 0 6 of the affected skin is removed, and a pathologist looks at it under a microscope. Once basal cell carcinoma has been diagnosed, treatment is essential. The speciﬁc treatment depends upon the location and severity of a lesion; the goal is to remove the entire lesion. A small, clearly delineated lesion may be treated by scraping and electrodessication (burning). Cryosurgery (freezing) is another accepted treatment. Surgical removal is optimal when additional pathology examinations are desired to ensure the entire tumor has been removed. If the tumor is large or near important or fragile tissues, such as on the face, microsurgery (sometimes called Moh’s surgery) may be performed. If basal cell carcinoma is found and treated early, nearly all patients are cured. However, a patient can have another lesion months or years later in another area of the skin. Tell your doctor about any suspicious lesions, and once a year ask your doctor to examine your skin to check for this cancer. Sun exposure increases your risk of basal cell carcinoma. People with fair skin, blond or red hair, and blue or green eyes are more susceptible because they don’t have as much skin pigment to ﬁlter the sun’s damaging UV rays. MO — Rear Adm.
