Moles
Understanding Moles and Their Formation

A mole, or nevus, is a skin growth that forms when certain skin cells divide more rapidly.
Most moles are dark or brown due to an accumulation of melanin, the skin's pigment. Melanin helps protect the skin from sunlight, and its production increases when we tan. It's common for adults to have 25-30 moles.
While every diagnosis is reviewed by a licensed clinician, AI allows us to streamline triage, improve accuracy, and deliver care in real time, without the wait. All of this works behind the scenes to make getting care feel simple, seamless, and proactive for you.
Which moles or skin marks are dangerous?
Asymmetry
One half differs from the other.
Border
Irregular or poorly defined edges.
Diameter
Larger than 6 mm.
Evolution
Changes in size, shape, color, or symptoms.
Color
Varies within the spot.
Some moles are congenital, while most appear later in life. Genetics influence how easily one gets moles, and sun exposure increases the likelihood of developing more.
Skin Cancer
Melanoma
Also called mole cancer, is the most dangerous type. The most important warning sign is a new spot on the skin or a mole that changes.
Basal cell and squamous cell carcinoma
The most common types of skin cancer. These are less critical but should also be removed.
Nolla helps you check all of these, as well as more rare types of cancer. Any spot can be scanned.

Melanoma occurrence has increased significantly among both men and women over the last 10 years.
Our 40% higher in Norway. Globally, Norway is in second place in terms of mortality due to melanoma, only surpassed by New Zealand.
One of the reasons why Norwegians fare so poorly in the statistics on mortality due to melanoma is that it is detected too late.
