What should you know about growth on neck skin?

The neck can develop skin tags, blocked follicles, cysts, and other [Skin Lumps](/symptoms/skin-lumps/). A red, warm, tender lump that contains pus may be a [Boil](/conditions/boils/). A rough or crusted spot that repeatedly bleeds or does not heal can be associated with [Basal Cell Carcinoma](/conditions/basal-cell-carcinoma/).

Collars, jewellery, hair removal, and sweat can irritate a surface growth, while a deeper lump may feel separate from the skin. A clinician looks at colour, border, surface, firmness, mobility, and the surrounding skin; these details are more useful than assuming a cause from location alone.

Book an examination if the growth is new, lasts beyond a short period, or is changing. Avoid picking, squeezing, cutting, or applying strong acids. Reduce rubbing from collars and chains, wash gently, and photograph the area in consistent lighting to document evolution.

Management depends on the diagnosis. An inflamed scar or selected raised lesion may sometimes be treated with a [Steroid Injection Into The Skin](/treatments/injectables/intralesional-steroid-injection/), while infection or a suspicious surface lesion needs a different plan. Treatment should follow inspection rather than self-diagnosis.

Seek prompt care for rapid growth, spontaneous bleeding, an ulcer or persistent crust, marked tenderness, spreading redness, warmth, pus, or fever. Arrange timely review for a firm fixed lump, a lesion with changing colour or uneven edges, or a sore that repeatedly returns. Emergency assessment is appropriate if infection is spreading quickly or you feel severely unwell.

Ask: Is the growth arising from the skin or underneath it? Does it resemble a boil, skin tag, cyst, or another lesion? Would a sample be useful? Which symptoms should prompt an earlier review, and how can I prevent collar or jewellery friction?
