Skin cancer is the out-of-control growth of abnormal cells in the epidermis, the outermost skin layer. It is caused by unrepaired DNA damage that triggers mutations, which cause the skin cells to multiply rapidly and form malignant tumors. The main types of skin cancer are basal cell carcinoma (BCC), squamous cell carcinoma (SCC), melanoma, and Merkel cell carcinoma (MCC).

Basal Cell Carcinoma is the most common skin cancer. It grows slowly in the basal cells and rarely spreads but requires treatment to prevent damage.
What to look for:
- A pearly, skin-colored, or pink bump
- A sore that won’t heal or keeps bleeding
- A flat, scar-like patch of skin
- A shiny, waxy area that may be red or brown
Early Detection:
Check for new, unusual growths, especially on sun-exposed areas (face, ears, neck, scalp, shoulders). See a dermatologist if a spot doesn’t heal, bleeds, or changes over time.
The second most common type of skin cancer, SCC, develops in the outer layer of the skin (squamous cells). If not treated, it can grow deeper and spread.
What to look for:
- A rough, scaly patch that may bleed or crust overA firm, red bump or growth
- A sore that doesn’t heal or keeps reopening
- Wart-like growths
Early Detection:
Pay attention to new or changing rough patches, especially on sun-exposed areas. Get checked if a sore doesn’t heal within a few weeks.
Melanoma is the most dangerous type of skin cancer. It starts in pigment-producing cells (melanocytes) and can spread quickly if not detected early.
Melanomas follow the ABCDE rule:
A – Asymmetry (one half looks different from the other)
B – Border (irregular, jagged, or blurry edges)
C – Color (multiple colors like black, brown, red, or blue)
D – Diameter (larger than a pencil eraser, but can be smaller)
E – Evolving (changes in size, shape, or color over time)
Early Detection:
Do monthly skin checks for unusual moles or spots. If a mole looks different or changes, see a dermatologist immediately.
A rare but aggressive skin cancer that starts in Merkel cells, found in the skin’s top layer. MCC can spread quickly to other parts of the body.
What to look for:
- A fast-growing, painless lump (often red, pink, or purple)
- A shiny or firm dome-shaped bump
- Found mostly on sun-exposed areas like the face, neck, or arms
Early Detection:
Watch for new, fast-growing lumps, especially if they appear shiny. If a bump grows rapidly or color changes, get it checked by a doctor.

Detecting skin cancer early is crucial—especially since it can significantly increase the chances of successful treatments and reduce the severity of the situation. When we can identify cancer early, it is often more responsive to treatments, meaning we can use less aggressive treatment, minimizing the physical and emotional impact. Early detection also increases the survival rates, especially for melanoma which is often a highly aggressive form of cancer. When we can catch it before it spreads, the five-year survival rate for melanoma is usually 99%. However, the survival rate can drop dramatically once it metastasizes to other organs. This is why early detection is so important. At the first sign of something unusual, you should seek medical and professional help.

IG-SRT is a non-surgical treatment that uses targeted, low-energy radiation to destroy cancerous cells at the skin’s surface.
At West Hills Dermatology, we proudly offer IG-SRT as an advanced option for patients seeking a painless, scar-free alternative to surgery.

For patients who require surgical treatment, we offer Mohs micrographic surgery—the gold standard for treating skin cancers with a high risk of recurrence or those located in delicate areas.
Mohs surgery offers the highest cure rates—up to 99%—while sparing the greatest amount of healthy tissue.

Photodynamic Therapy is a non-invasive treatment used primarily for precancerous lesions. PDT involves applying a light-sensitive topical agent to the skin, which is then activated by a specific wavelength of light. This process selectively destroys abnormal or precancerous cells while leaving healthy tissue unharmed.
