Detecting Squamous Cell Carcinoma: Prevention and Early Detection
By Dr Shirley Shen, General Practitioner at Madison Medical Practice Berowra
Skin cancer is the out-of-control growth of abnormal cells in the epidermis, the outermost skin layer, caused by unrepaired DNA damage that triggers mutations. These mutations lead the skin cells to multiply rapidly and form malignant tumors. The main types of skin cancer are basal cell carcinoma (BCC), squamous cell carcinoma (SCC), melanoma and Merkel cell carcinoma (MCC).
Squamous Cell Carcinoma (SCC) is a major type of cancer that arises from the outer epidermal layer of the skin and mucous membranes and occurs most commonly in areas exposed to the sun. If untreated, squamous cell carcinoma may penetrate and destroy underlying tissue. In a small percentage of cases, this tumour can spread (metastasize) to distant organs and may be fatal.
Chronic sun exposure is the leading cause of squamous cell carcinoma, especially in people with fair skin, light hair and blue, green or grey eyes. Other factors that may contribute to the development of this cancer include burns, scars, exposure to radiation or chemicals, chronic inflammatory conditions and immunosuppression.
Although more likely to develop in fair-skinned individuals, squamous cell carcinoma may occur in dark-skinned people, especially at sites of preexisting inflammatory conditions or burns.
Early detection of skin cancer can be a life saver. Scan your skin and look for a spot or a mole that is…
Sore: A spot which is sore (scaly, itchy, bleeding, tender) and doesn’t heal within 6 weeks.
Changing: Changing in size, shape, colour or texture.
Abnormal: Looks different, feels different, or stands out when compared to your other spots and moles.
New: Has appeared on your skin recently. Any new moles or spots should be checked, especially if you are over 40.
It’s your doctor’s job to diagnose skin cancer, but you will know better than anyone else if something on your skin is Sore, Changing, Abnormal or New. Remember – together with sun protection, early detection is your best defence against skin cancer.
