Raised bump on the Hand: Causes, Red Flags & When to Worry
Quick answer
A raised bump on the hand is usually a harmless growth like a firm scar bump from a minor injury, a crusty age spot, or a simple skin tag. Because our hands are constantly exposed to the elements, these benign spots are extremely common. However, since the backs of your hands catch so much sun over a lifetime, you should always have a doctor check any bump that bleeds, scabs, or refuses to heal, as this can be a warning sign of skin cancer.
Why a raised bump on the hand is different
The backs of the hands accumulate sun damage almost as quickly as the face, while the palms and finger webs are common sites for eczema, fungal infections and contact dermatitis.
The skin on your hands faces a unique set of daily challenges that impact how bumps form. The thin skin on the backs of your hands accumulates sun damage almost as quickly as your face due to decades of unprotected driving and outdoor exposure, making sun-related growths and skin cancers noticeably more common here. Meanwhile, the palms and finger webs lack hair follicles but endure constant friction, frequent hand-washing, and exposure to harsh chemicals or gloves. This means a bump in these areas is rarely a clogged pore or acne, but rather a blister from eczema, a reaction to an irritant, or a fungal infection. While most hand bumps are harmless reactions to this heavy daily wear and tear, their constant exposure to UV rays means new or changing spots should never be ignored.
The most common day-to-day triggers in this area are frequent hand-washing, glove and chemical exposure, driving sun exposure — each of which can produce or worsen a raised bump here.
Most likely causes
Dermatofibroma
Firm pea-sized bump that dimples when pinched.
Seborrhoeic keratosis
Waxy, stuck-on benign growth.
Skin tag
Soft, fleshy stalked growth in friction areas.
Basal cell carcinoma
Pearly, slowly-growing bump on sun-exposed skin.
