Are Dark Spots on the Hands a Sign of Melanoma?
Many people worry when they notice dark spots on their hands, asking: Could this be melanoma? The answer is yes — sometimes. While many dark spots are harmless age spots, some can signal early melanoma, the deadliest form of skin cancer.
What Is Melanoma?
Melanoma begins in melanocytes, the pigment-producing skin cells. It can appear on the backs of the hands, palms, or even under the fingernails (known as subungual melanoma).
Warning Signs of Melanoma
Dermatologists recommend using the ABCDE rule:
- A – Asymmetry: one half looks different from the other
- B – Border: uneven or ragged edges
- C – Color: multiple shades like brown, black, or red
- D – Diameter: larger than 6 mm
- E – Evolving: changing in size, shape, or color
Other red flags include spots that itch, bleed, crust, or look different from other moles.
Other Causes of Dark Spots
Not all hand spots are melanoma. They may result from sun exposure, natural aging, liver issues, hormonal changes, or vitamin deficiencies.
How to Protect Your Skin
Use sunscreen daily, eat antioxidant-rich foods, moisturize, and avoid smoking or excess alcohol. If spots change suddenly, always consult a dermatologist.
