When to worry about a non-healing skin sore with squamous cell skin cancer

Skin Sore That Does Not Heal is a very common presentation of Squamous Cell Skin Cancer. This cancer can appear as a rough or scaly patch, a crusted sore, or a raised growth that is tender to touch. It may develop on sun-exposed skin, but a clinician should assess any persistent or changing lesion.

Changes in thickness, firmness, bleeding, pain, or rapid enlargement can help the team judge how urgently to examine it. An open sore can also result from infection, injury, inflammation, or another skin condition, so appearance alone cannot establish the cause. Diagnosis may require a close examination and tissue sampling.

Arrange an appointment and avoid scraping, squeezing, or repeatedly removing the crust. Gently clean the area, cover it if clothing rubs against it, and protect surrounding skin from sun. Write down when the sore began and whether it has changed in size, texture, colour, bleeding, discharge, or pain.

Tell the clinician about earlier skin cancers, treatments to the same area, medicines that affect healing, and any immune condition. These details can shape examination, biopsy planning, and treatment choices.

Seek prompt review when the sore remains open, becomes thicker or harder, repeatedly bleeds, develops a raised edge, or causes increasing tenderness. Contact the team quickly if it is near an eye, ear, nose, mouth, or a joint, where a growing lesion may interfere with function.

Get urgent help if bleeding continues despite firm gentle pressure, or if there is spreading redness, warmth, swelling, pus, fever, or severe pain. After treatment, report a sore that returns or fails to settle at the treated site rather than waiting for a scheduled check.

Ask whether the lesion needs a biopsy, how deep it appears, and which treatment choices may be suitable. Ask how to dress the area, what healing changes are expected, when the result will be discussed, and how to check the rest of your skin.
