Importance Of Skin Cancer Screenings

Skin cancer is the most common type of cancer, and the incidence of skin cancer continues to rise. Generational norms have contributed to the increasing numbers of cancer patients. For example, the common practice of 'sunbathing' or 'suntanning,' often with the use of baby oil, was commonplace several decades ago. More recently, increased use of tanning beds has contributed to the increase in skin cancer diagnoses.

Societal definitions of beauty also contribute to the increase in risky behavior that may cause skin cancer. In the developed world, there is often a preoccupation with achieving a tan complexion. Again, the use of tanning beds exposes skin to ultraviolet radiation, often at very young ages, and may increase the risk of developing skin cancer several fold.

Ultraviolet (UV) radiation is the primary factor in the development of skin cancer. This type of radiation is emitted by the sun, and unlike UVC which does not reach the earth's surface, UVA and UVB are minimally blocked by the ozone layer and are carcinogenic (cancer causing). The ongoing exposure to UV radiation leads to mutations within the primary skin cells the basal cells, squamous cells, and melanocytes. Mutation of DNA from prolonged and cumulative sun exposure leads to skin cancer. It is possible, however, to develop skin cancer in areas not regularly exposed to sunlight. When we are regularly exposed to UV radiation, our skin's natural immunity is decreased, paving the way for cancers to form anywhere on the body.

Skin cancer is highly preventable. In order to protect your skin, you need education from experts in the area of skin health. Board certified dermatologists have received extensive training in the accurate diagnosis and treatment of skin cancers. During routine skin cancer screenings, it is possible for your experienced dermatologist to identify skin cancer on sight, confirming diagnosis with a skin biopsy.

In addition to performing skin cancer screenings, your dermatologist may use this type of visit as a starting point from which patients can begin skin care routines. During a professional screening, you gain a great deal of familiarity with your own skin. We discuss with you what to look for, and what types of growths or changes should be immediately evaluated. We provide preventive treatment for areas of sun damage using chemical peels and photodynamic therapy.

When to see the doctor

Regular screenings are important, however, a professional evaluation with a board certified dermatologist should always be scheduled if changes are noticed in an existing mole or if a new spot on the skin appears. Other concerning signs include bleeding or itching in an existing or new mole.

Self-examinations as well as professional skin cancer screenings are an important part of maintaining healthy skin. To further assess a suspicious lesion, your dermatologist may recommend taking a small sample, or biopsy, for examination under a microscope. If skin cancer is detected, treatment is planned according to a number of factors.

Treatment for skin cancers may involve

Freezing, called cryosurgery

Excision, or surgically removing the lesion using local anesthetic

Application of topical chemotherapy

Laser treatment to activate medication against cancer cells

Understandably, skin cancer can seem like a very scary condition. However, most skin cancers can be successfully treated when detected early. Contact an experienced, board certified dermatologist to set up a consultation as soon as possible.
