Photodynamic Therapy (cont.)

What is the chance that my precancers will recur?

While PDT is a very effective treatment, there is a reasonable chance that you may continue to need periodic treatments for precancers depending on your individual skin and severity of prior sun damage. Often there are layers of underlying sun damage from prior years that rise to the surface over time.

A skin precancer or cancer may recur or a new cancer may arise in the same or adjacent area even after photodynamic therapy or other treatments. Some skin precancers are more aggressive than others and need additional treatment and closer follow-up.

Sun-damaged skin frequently needs additional follow-up and possible further treatment, at least annual rechecks and possible touchup PDT treatments are advised. Several studies have shown that photodynamic therapy tends to have a cure rate comparable to the traditional treatment with fluorouracil.

It is important to note that PDT may not be necessarily curative in advanced skin cancer (rare cases). This may require one or more procedures such as biopsy, surgery, radiation or other procedures to fully treat the lesion.

Follow-up appointments with your dermatologist or physician are very important, especially in the first few years after photodynamic therapy. Many patients are seen every four to six months after their diagnosis of precancers of the skin.

Self-skin examinations monthly are good practice for patients with a history of skin cancer. Any changing or new growth should be promptly checked by your physician. More regular follow-up appointments may be needed for those with more aggressive tumors or tumors in high-risk areas. Your physician will recommend the proper follow-up for your specific condition.

    • Lung Cancer
      • Lung cancer kills more men and women than any other form of cancer. Eight out of 10 lung cancers are due to tobacco smoke. Lung cancers are classified as either small cell or non-small cell cancers.
    • Psoriasis
      • Psoriasis is a long-term skin condition that may cause large plaques of red, raised skin, flakes of dry skin, and skin scales. There are several types of psoriasis, including psoriasis vulgaris, guttate psoriasis, inverse psoriasis, and pustular psoriasis. Symptoms vary depending on the type of psoriasis the patient has. Treatment of psoriasis may include creams, lotions, oral medications, injections and infusions of biologics, and light therapy. There is no cure for psoriasis.
    • Acne (Pimples)
      • Acne is a localized skin inflammation as a result of overactivity of oil glands at the base of hair follicles. This inflammation, depending on its location, can take the form of a superficial pustule (contains pus), a pimple, a deeper cyst, congested pores, whiteheads, or blackheads. Treatments vary depending on the severity of the acne.
    • Skin Cancer
      • Skin cancer is the most common form of cancer in humans. There are three main types of skin cancer; basal cell carcinoma and squamous cell carcinoma (the nonmelanoma skin cancers), and melanoma.
    • Warts (Common Warts)
      • Common warts are skin growths causes by the human papillomavirus. There are many types of warts, including plantar warts, common hand warts, warts under the nails, mosaic wars, and flat warts. Over-the-counter treatments typically involve the use of salicylic acid products.
    • Rosacea
      • Rosacea is a skin disease that causes redness of the forehead, chin, and lower half of the nose. In addition to inflammation of the facial skin, symptoms include dilation of the blood vessels and pimples (acne rosacea) in the middle third of the face. Oral and topical antibiotics are treatments for rosacea. If left untreated, rhinophyma (a disfiguring nose condition) may result.
    • Esophageal Cancer
      • Esophageal cancer is a disease in which malignant cells form in the esophagus. Risk factors of cancer of the esophagus include smoking, heavy alcohol use, Barrett's esophagus, being male and being over age 60. Severe weight loss, vomiting, hoarseness, coughing up blood, painful swallowing, and pain in the throat or back are symptoms. Treatment depends upon the size, location and staging of the cancer and the health of the patient.
    • Alcoholism
      • Alcoholism is a disease that includes alcohol craving and continued drinking despite repeated alcohol-related problems, such as losing a job or getting into trouble with the law.
    • Keloid
      • A keloid is a scar that doesn't know when to stop. When the cells keep on reproducing, the result is an overgrown (hypertrophic) scar or a keloid. A keloid looks shiny and is often dome-shaped, ranging in color from slightly pink to red. It feels hard and thick and is always raised above the surrounding skin.
    • Cancer
      • Cancer is a disease caused by an abnormal growth of cells, also called malignancy. It is a group of 100 different diseases, and is not contagious. Cancer can be treated through chemotherapy, a treatment of drugs that destroy cancer cells.
    • Keratosis Pilaris
      • Keratosis pilaris (KP) is a common skin disorder in which small white or red bumps appear around hair follicles on the upper arms, thighs, buttocks, and cheeks. The cause of KP is unknown. There is no cure for keratosis pilaris, and the condition may resolve on its own. Gentle exfoliation, professional manual extraction, chemical peels, and microdermabrasion, along with topical products, are the best treatments for this condition.
    • Actinic Keratosis
      • Actinic keratoses are rough, scaly patches of skin that are considered precancerous and are due to sun exposure. Prevention is to cut sun exposure and wear sunscreen.
    • Barrett's Esophagus
      • Barrett's esophagus occurs as a complication of chronic gastroesophageal reflux disease (GERD), primarily in white males. GERD refers to the reflux of acidic fluid from the stomach into the esophagus (the swallowing tube), and is classically associated with heartburn.
    • Smoking (How to Quit Smoking)
      • Smoking is an addiction. More than 430,000 deaths occur each year in the U.S. from smoking related illnesses. Secondhand smoke or "passive smoke" also harm family members, coworkers, and others around smokers. There are a number of techniques available to assist people who want to quit smoking.
    • Scars
      • Scar formation is a natural part of the healing process after injury. The depth and size of the wound incision and the location of the injury impact the scar's characteristics, but your age, heredity and even sex or ethnicity will affect how your skin reacts.
    • Macular Degeneration
      • Age-related macular degeneration (AMD) is a disease that gradually destroys the central vision. In people over 60, AMD is a leading cause of vision loss. Wet AMD occurs when abnormal blood vessels behind the retina start to grow under the macula, leaking blood and fluid and causing rapid vision loss. In dry AMD, light-sensitive cells slowly break down in the macula, resulting in gradual vision loss. Pain is not associated with either form of AMD.
    • Wrinkles
      • Wrinkles, whether they be fine line or deep furrows, typically appear on areas of the body that receive a high amount of exposure to the sun. Smoking, light skin type, hairstyle, the way you dress, your occupational and recreational habits, and heredity are all factors that promote wrinkling. Medical treatments for wrinkles include antioxidants, moisturizers, alpha-hydroxy acids, and vitamin A acid. Cosmetic procedures that treat wrinkles include dermabrasion, microdermabrasion, glycolic acid peels, laser resurfacing, Botox, and fillers.
    • Sunscreen
      • Sunscreens are crucial for sun protection. Sun damage to the skin from exposure to ultraviolet rays is a risk factor for skin cancer and melanoma. To avoid sunburn, people should limit sun exposure during the peak hours of 10 a.m. to 3 p.m., wear protective clothing, and use a sunscreen. People with sensitive skin should use a sunscreen with an SPF of 30 or more.
