Melanoma is the least common but most aggressive and dangerous type of skin cancer. If it not caught early, it can be fatal. For this reason, it is important to have moles examined annually, particularly if they are unusual or changing or if you have a personal or family history of melanoma. At Snyder Dermatology, led by board-certified dermatologist Dr. Renee Snyder, we examine moles to ensure they are healthy. Melanoma generally begins with a mole (either existing or new) that has changed and shows signs of irregularity. In most patients, this means the mole has become very dark in color, has irregular borders, has begun to grow in size, itch, or bleed.
How does melanoma form? Melanocytes (pigmented cells in the epidermis) may turn malignant when exposed to sun or ultraviolet light that causes DNA damage to the cells. This DNA damage allows cells to mutate and grow rapidly, creating melanoma. Some people may also have an inherited predisposition for melanoma, making DNA damage from UV light particularly dangerous. Because the vast majority of melanomas can be seen on the skin, consistent mole checks and self-exams are very important to aid in early diagnosis and treatment. Call Snyder Dermatology today to schedule your mole check and skin examination.
"Dr Renee Snyder has saved my life many times. I am a melanoma survivor. She is an amazing doctor that is patient and caring. She listens to your concerns and helps you overcome your fears. I'm blessed to have found her."- N.R. / Facebook / Jun 25, 2014
"One evening I was getting ready for bed, scratched my back, and came away with blood. I looked in the mirror and saw a mole that looked exactly like all the ones that I'd seen in brochures of what moles aren't supposed to look like. I researched dermatologists, called Dr. Snyder's office, and set up an appointment as soon as possible. Dr. Snyder did a full skin check, confirming that the mole was really funky looking, and did a punch biopsy straight away. Just under a week later I got a phone call from her confirming that it was a melanoma, and we made an appointment for a wide local excision. I had another atypical mole excised a few months post-melanoma surgery, and since then I've had regular skin checks and several biopsies. Dr. Snyder really knows her stuff, and her professional demeanor and ability to answer all of my questions in a straightforward way puts me at ease. She's friendly and nice, but she's more focused on the task at hand than trying to be my bestie. Given most of my appointments with her have involved wearing nothing but a hospital gown and/or being cut open, professionalism and efficiency are key. The office is clean and bright and the staff are super nice. Parking isn't free and there's a bit of a dipsydoodle to get from the parking garage down to the lobby to go up to the 4th floor, but I'm really happy to have found a doctor I can trust."- M.F. / Yelp / May 01, 2012
"I saw Dr. Aranda for a suspicious spot on my face and an annual skin check due to family hx of melanoma. She has a great bedside manner. She was completely present with me and did not rush through the visit...very thorough and concerned. I highly recommend her. Her staff, front AND back office were excellent as well."- A.V. / ZocDoc / Oct 24, 2015

"I have been going to Dr Renee Snyder for several years. This year I had a discolored area on my face and Dr. Parker did a biopsy. The biopsy came back negative but Dr. Parker wanted to re biopsy. It came back melanoma in situ. I had the Mohs surgery with Dr. Dietert. It was extensive. I was fortunate to have Dr Ned Snyder perform surgery to close the incision and he and his team did a beautiful job. If Dr. Parker had not wanted to re-biopsy, I might have had a very serious outcome. Needless to say, this is an amazing team. The follow-up has been outstanding by Dr. Ned Snyder and his PA Jen Bader . I will forever be grateful to Dr. Parker, Dr. Dietert and Dr. Ned Snyder and Jen Bader. Thank you"- P.B. / Yelp / Dec 31, 2018
Those at Risk
Melanomas can affect both men and women and are thought to be mostly caused by genetics and sun exposure. A history melanoma in a primary relative (parent, sibling, or child) increases your risk of developing this malignancy. In addition, your chances of developing a melanoma increase if you have:
- Many moles on your body
- Multiple large moles
- Tanned in a tanning bed
- Experienced multiple or severe sunburns
- Blue, green, or gray eyes
- Light colored or red hair
- Excessive sun exposure (even if it did not lead to a sunburn)
If you have moles on your skin, it is important to understand which ones may be at risk for developing into melanoma. Generally, melanoma starts with an atypical mole. This means the mole looks "different" than most others. It may be new, dark or black, have an irregular border, or start to change. Atypical moles can be removed and ongoing mole checks will help catch any potential problem quickly.
Malignant lesions can be challenging to recognize, especially to the untrained eye. Having regular skin cancer screenings by a trained, board-certified dermatologist is essential. We educate our patients on the presenting symptoms of melanoma with the ABCDE rule. These are the signs to look for in moles that may signal the lesion is concerning and include:
- A: Asymmetrical mole (one side is larger than the other, not round or oval in shape)
- B: Borders on the mole (a malignant mole will not have a defined, smooth border)
- C: Color (a malignancy will be various colors throughout the mole or very dark)
- D: Diameter (benign moles usually stay small — moles larger than a pencil eraser are concerning)
- E: Evolving (cancer cells in a malignant mole will keep changing and growing)
While some benign moles or freckles may have some of these characteristics, you should always make an appointment with your dermatologist to have spots with these concerning features examined.
Snyder Dermatology has multiple board-certified dermatologists with specialized training to screen for and treat skin cancer. Treatment for melanoma is based on the type and stage of melanoma, size, and location. Our experienced providers at Snyder Dermatology will work closely with you and discuss the appropriate treatment, which usually includes excision with a standard margin. If needed, our team will work with cancer specialists to assist in your treatment. In certain cases, additional diagnostic testing may be needed, such as a PET or CT scan, blood work, and lymph node biopsy.
