Skin cancer does not discriminate. Anyone of either gender or any ethnicity, age, or lifestyle can develop it. Fortunately, today’s patient has more options in skin cancer treatments than ever before. It starts with accurate diagnosis at Grossmont Dermatology Medical Clinic in La Mesa, CA.

How skin cancer is diagnosed 

Human skin is comprised of four layers containing many kinds of cells. Skin cancer is abnormal growth of skin cells. While most people are familiar with basal cell carcinoma, squamous cell carcinoma, and melanoma, there are more than 100 types of skin cancer. Pinpoint diagnosis requires skill, experience, and advanced instrumentation, essential for an effective treatment plan.


As Board-certified dermatologists, Doctors Dean, Crosby and Lynn have seen and treated a multitude of skin cancers. He begins with thorough examination of skin, looking under magnification for changes that may indicate cancer. Laboratory testing, called a biopsy, may be necessary to confirm diagnosis of a suspicious spot. They strive to precisely analyze the extent or stage of the skin cancer. Imaging tests help to identify involvement of nearby tissues or lymph nodes.

Tailored treatment 

The most effective course of treatment may involve:

  • Mohs micrographic surgery. With this precise removal method, there is an extremely high cure rate with minimal impact to healthy, surrounding tissues.
  • Immunobiological treatment that boosts the body’s natural defense mechanisms, to attack cancer naturally.
  • Traditional excision involves cutting the lesion and a portion of surrounding tissues from skin.
  • Curettage and electrodesiccation, a time-tested technique for small, low-risk lesions.
  • Cryosurgery, freezing, can be a good choice for patients who have bleeding disorders.
  • Photodynamic therapy. PDT is sometimes used on the face and scalp. Lesions are treated with sensitizing medications; then a special light is applied.
  • Laser surgery is sometimes used for superficial lesions.
  • Topical medications are a form of chemotherapy. They are appropriate for pre-cancerous actinic keratosis some surface cancers.
  • Radiation. Although the cure rate is high with radiation therapy, cosmetic issues and side effects make this a last resort treatment.


The prognosis for most skin cancers is good, with early detection and leading-edge care. Call [phone] to schedule treatments with Dr. Crosby in La Mesa, CA.
