Extra growth on the skin: what to know

Skin growths vary in texture, color, depth, and speed of change. A tender, red, warm bump containing pus may fit a boil, while a firm lump under the surface can have another cause. Some basal cell carcinomas appear as a pearly bump, a sore that does not heal, or a spot that repeatedly crusts or bleeds; these signs are not a diagnosis, but they merit review. A growth can also be irritated by clothing, shaving, or picking. Do not assume that a painless lesion is harmless or that every growth is cancer.

Take a clear photo beside a familiar object and note when you first noticed the growth, whether it changes, and whether it itches, hurts, crusts, or bleeds. Do not squeeze, cut, burn, or tie off a lesion at home. Protect it from friction and sun exposure while arranging an appointment. A clinician may inspect it with magnification and decide whether observation, removal, or a sample is appropriate. Steroid injection into the skin is used only for selected inflammatory lesions after diagnosis.

Seek a prompt appointment for a growth that changes in size, shape, or color; bleeds without clear injury; repeatedly crusts; becomes painful; or fails to heal. Arrange urgent care for rapidly spreading redness, severe pain, fever, or swelling around the eyes or airway. Mention immune suppression, prior skin cancer, and significant sun exposure because these details affect assessment.

What features do you see, and does this need monitoring, removal, or sampling? Could friction or inflammation be contributing? How should I protect and check the area while waiting?
