Did you know that itchiness can be a sign of skin cancer — but not always? Let's learn more about itchy spots on the skin and when you should be concerned about a malignancy.
An itchy spot on your skin can be a sign of skin cancer, but not every itchy spot is cancerous; it could also be a symptom of a different dermatological condition. Similarly, not every skin cancer will feel itchy — so, just because your spot isn't showing any symptoms, doesn't mean it's harmless.
Itchiness can be a sign of non-melanoma skin cancers including basal cell carcinoma and squamous cell carcinoma.
Basal cell carcinoma (BCC) is the most common type of skin cancer and usually develops on sun-exposed areas of the body and face, especially in older people. Most BCCs are caused by sun exposure. Signs can include:
Squamous cell carcinoma (SCC) is the second most common type of skin cancer and is also common on sun-exposed areas where sun damage occurs. Signs can include:
SCC can be very painful, causing local tissue destruction if not treated early. It can also spread to other areas of the body and sometimes become fatal.
Always keep in mind the ABCDE guide to help identify some skin cancers, such as melanoma. This includes asymmetrical moles, moles with irregular borders, moles larger than six millimetres, moles with multiple colours, and moles that are growing.
Other signs of skin cancer can include:
If you have any spots that are sore, itchy, new, changing, or stand out from the others, it's important to get a full-body skin check as soon as possible.
In addition to self-monitoring your skin at home every few months (checking for the signs and symptoms of skin cancer mentioned above), it is also essential to see a doctor with advanced training in skin cancer medicine for a full-body skin examination every year, even if you haven't found anything suspicious. You should see them more often if the doctor recommends it.
This is because a dermoscopic examination is the only way to know for sure whether a spot is skin cancer. You cannot always see skin cancer with the naked eye. The doctor will examine your entire body with a dermatoscope, which is a special skin microscope that allows them to see beneath the skin to identify malignancies.
If the doctor finds a suspicious spot, they might take a photograph to be analysed, and they might take a biopsy which is sent to a dermatopathology laboratory to confirm the diagnosis.
If you have an itchy spot on your skin, remember that an early skin cancer diagnosis provides the best chance of successful treatment and cure.
