What should you know about soft movable lump under skin?

A lump that shifts under gentle pressure may be separate from the surface skin, but this finding is not enough to name it. Cysts, fatty tissue, an irritated follicle, and other lesions can feel mobile. Note whether the skin moves with it, whether there is a central pore, and whether pressure causes pain. The [Skin Lumps](/symptoms/skin-lumps/) guide can help organise those observations. A surface change such as crusting or bleeding needs a clinician to consider several diagnoses, including [Basal Cell Carcinoma](/conditions/basal-cell-carcinoma/), without assuming the lump is cancer.

Measure or photograph the area for comparison without repeatedly handling it. Avoid squeezing, piercing, or trying to push it deeper. Book a medical examination if it lasts, enlarges, becomes less mobile, or affects movement or clothing. If the lump is inflamed, a clinician may discuss options such as treating infection or, in selected cases, [Steroid Injection Into The Skin](/treatments/injectables/intralesional-steroid-injection/).

Seek prompt advice if the lump grows quickly, becomes very painful, feels hot, drains pus, or is accompanied by fever or spreading redness. Arrange timely review for bleeding, an open sore, persistent crusting, or a lump that becomes hard and fixed. These warning signs are based on the change itself, not on the fact that the lump is movable.

Ask whether the lump is superficial or deeper, whether an ultrasound is appropriate, whether observation is reasonable, and which changes should lead you back sooner.
