Skin cancer is the
most common cancer, but it is also the most easily cured type when it is
diagnosed early and treated promptly.
UT Southwestern
Medical Center’s specialized physicians are experts at screening for and
diagnosing all types of skin cancer. Many also are involved in clinical research aimed at developing more effective
ways to detect and diagnose the disease.
Skin Cancer Screening
Screening helps
UT Southwestern specialists find and treat skin cancer before symptoms
appear. To detect precancerous moles and spots, our doctors use proven
screening methods that include:
Physical exams
Our specialized physicians
conduct thorough physical examinations aimed at recognizing skin abnormalities
that could be cancerous or precancerous. They often use a high-powered
microscope called a dermatoscope to get a highly detailed look at the skin.
If patients have a suspicious
mole or growth – or a patch of skin that has changed in shape, color, size, or
texture – they should point it out to their doctor.
Full-body photography
For patients who have
numerous moles on their body or a family history of skin cancer, our doctors
might take photos of their body from different angles. These images will be
used as a baseline to help track any changes over time.
Pigmented Skin Lesion Clinical Practice
The only service of
its kind in North Texas, this UT Southwestern clinic follows patients with
cancer syndromes (such as Cowden syndrome and Gorlin syndrome), patients with dysplastic
nevi syndrome, those who have undergone organ transplants, and those with
strong family histories of skin cancer.
The goal is to
identify patients with suspicious moles or other pigmented lesions so that
cancerous changes can be detected, treated early, and, in some cases,
prevented.
Diagnosis
A biopsy (tissue
sample) is used to get a definitive diagnosis of skin cancer. If we suspect
that a spot on the skin is cancerous or precancerous, we will remove a small
sample of the questionable tissue and send it to UT Southwestern’s pathology specialists for evaluation under a microscope.
If skin cancer is
confirmed, our pathologists use additional laboratory testing to determine its
exact type and stage (the degree to which it has spread).
We offer in-house
molecular profiling of skin cancers, which enables doctors to identify key
mutations (such as the BRAF gene
in melanoma) and other patient-specific characteristics of the disease. This
sophisticated evaluation technique helps our physicians recommend highly
personalized, evidence-based therapies.
The doctor might also
take a biopsy of the lymph node closest to the cancerous spot (the sentinel
lymph node) or remove the lymph nodes near the affected spot (dissection) to
determine if the cancer has metastasized (spread) beyond that spot to other
parts of the body.
All diagnostic tests
help us determine the most appropriate course of treatment.
Staying Healthy
While every case of skin cancer is different, our skin cancer experts recommend these general guidelines to people previously diagnosed with the disease:
- See a dermatologist for follow-up care and skin cancer screening as often as he or she suggests. Patients who have had melanoma and other particularly aggressive skin cancers might be advised to follow up regularly with their oncologists or surgeons as well.
- Minimize sun exposure. Avoiding the sun can be a major lifestyle change for people who enjoy being outdoors, but it’s critical for those who have had skin cancer to protect their skin. When patients must be in the sun, they should wear long clothing, a hat, and sunglasses – and apply sunscreen liberally to exposed skin every two hours.
