Is It A Mole Or Another Skin Growth? Here’s How You Can Tell

As public awareness about the dangers of skin cancer grows, many people are increasingly scrutinizing even the smallest blemishes on their skin. Experts advise that any noticeable change in existing moles—or the appearance of new ones—should be taken seriously, as these may serve as early warning signs of skin cancer and may warrant timely mole removal treatment.

At the same time, differentiating moles from other skin growths can be challenging for the untrained eye. Skin tags, warts, and other blemishes may closely resemble moles, leading to confusion about the potential risk of skin cancer. In the sections below, we explore what moles look like as well as the most common skin growths that look similar to them so you can more easily tell them apart.

What is a Mole?

Moles are clusters of melanocyte cells that usually appear as black or brown spots. They generally occur singly but can sometimes appear in groups and are often raised, which is a primary identifying feature. Over time, moles may change in shape, size, and color as they naturally evolve, sometimes making it difficult to determine whether these changes are benign or a sign of skin cancer. Typically, moles tend to lighten gradually as they fade. However, if a mole exhibits consistent or concerning changes, it is advisable to consult a dermatologist at an aesthetic clinic in Singapore.

There are different types of moles, the most common of which are:

• Atypical Moles: These are usually larger than 6 mm and may have both flat and raised areas. Their irregular shape, size, and color—often appearing splotchy or fuzzy—can be alarming, particularly if they cause itching or irritation.
• Acquired Moles: Also known as common moles, these typically develop after birth. Measuring about 5–6 mm, they have a smooth surface with pigmentation that can vary from light to dark brown. Although they are often linked to sun exposure, they rarely turn malignant.
• Congenital Moles: Present at birth, these moles can appear as single or multi-shaded, round or oval patches that may be 1.5 cm or larger. They can sometimes exhibit increased hair growth and have a slightly rough or bumpy texture.

What are Freckles?

Freckles are small, clustered spots on the skin that usually develop after prolonged sun exposure. They form when UV rays stimulate the production of melanin. Unlike moles, freckles almost always occur in groups rather than individually, and their appearance can vary slightly in color based on genetics and skin tone. Typically, they are only a few shades darker than the surrounding skin.

There are two main categories of freckles:

• Lentigines: Also known as sun spots, these freckles are primarily induced by sunburn and tend to be darker in appearance. Unlike ephelides, they do not fade easily with reduced sun exposure and are commonly found on the face, arms, and chest.
• Ephelides: Common freckles that are often influenced by both sun exposure and genetics. They are more prevalent in individuals with lighter skin or red/blonde hair and usually appear on areas frequently exposed to the sun, such as the face, hands, and upper body. These freckles may brighten or become more noticeable during the summer months.

What is a Skin Tag?

Skin tags, medically referred to as acrochordons, are small, benign skin growths that are typically skin-colored or brown. They are called “tags” because they often have a narrow base and dangle from the skin. Skin tags most frequently occur in areas where the skin experiences friction and tend to be more common with advancing age and may run in families.

These small flaps of skin can range from the size of a pen tip to as much as three centimeters. The common areas in the body that are prone to friction and experience repetitive rubbing are the neck, armpits, and groin, causing these small bumps  to protrude and eventually evolve into a tag-like formation.

What are Warts?

Warts are small, rough growths that appear on the skin’s surface, most commonly found on the hands, fingers, and toes. They are caused by the human papillomavirus (HPV), which means they are contagious. Unlike moles, warts are classified as a type of skin infection that can spread through direct contact or by sharing personal items such as towels or clothing.

Typically, warts are grainy bumps with a hardened texture and may feature tiny black dots that represent clotted blood vessels. Although their color usually blends with the surrounding skin, they can sometimes appear darker.

What are Dermatofibromas?

Dermatofibromas are benign skin growths that generally have a small diameter. Their color can range from pink to light brown on lighter skin and dark brown or black on darker skin. These growths may appear more pronounced if irritated, for instance, during shaving. Usually measuring between 0.5 and 1.5 cm (with most between 0.7 and 1.0 cm), dermatofibromas tend to remain stable over time. While they are generally harmless and painless, some individuals may experience occasional itchiness, tenderness, or inflammation.

Conclusion

Understanding the characteristics of various skin growths—from moles and freckles to skin tags, warts, and dermatofibromas—is crucial to better recognizing potential warning signs of skin cancer. However, any persistent or concerning changes should be evaluated by a dermatologist to ensure early detection and appropriate treatment.
