Skin Cancer Detection & Treatment

Skin cancer refers to the abnormal, uncontrolled growth of skin cells. One in five people will develop skin cancer in their lifetime. Fortunately, skin cancer is almost always curable if detected and treated early. Complete full body skin exam by your dermatologist is the best skin cancer early detection and prevention.

The most common skin cancers are:

  1. Basal cell carcinoma - 80-85% of all skin cancers. Basal cell carcinoma affects cells in the lowest layer of the epidermis.
  2. Squamous cell carcinoma - 10% of all skin cancers. Squamous cell carcinoma affects cells in the middle layer of the epidermis.
  3. Melanoma - 5% of all skin cancers. Melanoma is a rare but very dangerous type of skin cancer. It is the leading cause of death from skin disease. Skin cancers vary in shape, color, size and texture, so any new, changed or otherwise suspicious growths or rashes should be examined immediately by your dermatologist. Early intervention is essential to preventing the cancer from spreading.

Moles and other birthmarks are benign pigmented spots or patches of skin that range in color from tan, brown and black (moles) to red, pink or purple (vascular lesions). The medical term for a mole is a NEVUS. Moles that appear after age 50 should be regarded with suspicion.

Acne is a common skin condition that afflicts most people, to a varying degree, during the teen years. However, adults in their 20's or 30's may have acne. Treatment, depending on the type and severity of lesions, as well as the patient’s skin type, age and lifestyle, can improve your appearance and self esteem, and prevent the development of lifelong scars.

Eczema / Atopic Dermatitis

Eczema, is a chronic skin that causes areas of red, itchy skin. This condition usually starts in early childhood, especially when there is a family history of atopy (asthma, hay fever, conjunctivitis, or food allergies). Dermatologists may prescribe topical corticosteroids, topical immunomodulators, antibiotics to combat infection, or sedative antihistamines and phototherapy. For severe cases, oral immunosuppressants such as cyclosporine A may be recommended.

Pigmentary Irregularities or Melasma

Melasma, also known as cholasma, is characterized by irregular patches of dark skin on the face. These tan or brown patches usually occur symmetrically on the cheeks, upper lip, nose, or forehead.  Melasma is found more often in women. Those with darker skin types (including  Hispanics, Middle-Easterners, and Asians) are more prone to melasma than those with lighter complexions.

The cause of melasma is not fully understood. However, genetics, hormonal changes, and excessive sun exposure are known to play important roles.

Treatments for melasma may include: UVA/UVB Sunscreen of SPF 30 or higher, bleaching or depigmenting Agents including Hydroquinone, Kojic Acid, Azelaic Acid and laser therapy such as CO2 laser resurfacing and IPL.

Warts are simply areas of skin that grow faster than normal due to the presence of wart viruses. Liquid nitrogen is what dermatologists use most often to cure warts. Burning warts off with a CO2 laser or electric needle is often effective. A more effective laser is the pulsed dye laser since there is absolutely no downtime from pain, and scarring is rare.

The medical term for excessive sweating is hyperhidrosis. The armpits and the palms are the areas most often troublesome. The best product is available by prescription (Drysol).
