When it comes to skin cancer, early detection can make all the difference. The good news is that most forms of skin cancer, including melanoma, are highly treatable when caught early. At Texas Surgical Dermatology, our team emphasizes the importance of regular skin checks and mole monitoring so patients can protect their health and peace of mind. Knowing what to look for—and when to see a dermatologist—can truly save your life.
Why Early Detection Matters
Skin cancer is the most common type of cancer in the United States, but it’s also one of the most preventable. When detected early, even aggressive types like melanoma can be treated effectively before they spread. Routine skin exams and self-checks help identify suspicious spots while they’re still in the earliest, most curable stages.
What to Look for in Moles: The ABCDE Rule
Almost everyone has moles or freckles, and most are harmless. However, some changes in a mole’s appearance may indicate an early warning sign of skin cancer. Dermatologists use the ABCDE rule to help patients recognize potential warning signs:
-
A – Asymmetry: One half of the mole looks different from the other in shape, color, or size.
-
B – Border: Irregular, jagged, or blurred edges.
-
C – Color: Uneven coloring, such as multiple shades of brown, black, red, white, or blue.
-
D – Diameter: Larger than 6mm (about the size of a pencil eraser).
-
E – Evolving: Any change in size, color, shape, or elevation—or new symptoms like itching, bleeding, or crusting.
If you notice one or more of these changes, it’s time to schedule a professional evaluation with a board-certified dermatologist.
High-Risk Areas Often Overlooked
Skin cancer can appear anywhere on the body—not just in areas exposed to sunlight. Be sure to examine:
-
The scalp and behind the ears
-
Between toes and on the soles of the feet
-
Under fingernails and toenails
-
The back, shoulders, and neck
-
Underarms and genital areas
Because some of these areas are difficult to see, consider asking a partner for help or scheduling regular full-body skin exams.
When to See a Dermatologist
Monthly self-exams are important, but professional skin cancer screenings remain the gold standard for early detection. You should book an appointment if you notice:
-
A new mole or growth that looks different from others
-
A sore that doesn’t heal after several weeks
-
Persistent itching, tenderness, or bleeding
-
Rapid color or texture changes in an existing mole
Individuals with fair skin, a history of sunburns, numerous moles, or a family history of melanoma should schedule a full-body skin check annually.
The Role of Mohs Surgery in Skin Cancer Treatment
When skin cancer is diagnosed, Mohs micrographic surgery offers the highest cure rate—up to 99% for many basal cell and squamous cell carcinomas. This precise, layer-by-layer technique allows dermatologic surgeons to remove all cancerous tissue while sparing as much healthy skin as possible. Texas Surgical Dermatology, led by Dr. Tri H. Nguyen who is a Mohs fellowship-trained specialist, provides Mohs surgery to patients in Houston, Katy, Spring, The Woodlands, Texas, and surrounding locations.
Prevention Tips for Healthier Skin

-
Avoid tanning beds and minimize sun exposure between 10 a.m. and 4 p.m.
-
Wear protective clothing, hats, and UV-blocking sunglasses.
-
Keep track of your moles by taking photos and comparing them over time.
