The best way to prevent the metastasis of squamous cell carcinoma is to take measures to reduce your risk of skin cancer altogether. Limit your sun exposure, do not use tanning beds, and when in the sun use a high SPF, natural sunblock to protect your skin from UVA and UVB damage. Eating a healthy diet that is rich in fresh fruits and vegetables and whole grains is also known to help prevent cancer and to strengthen the immune system.
Check your skin regularly for abnormal markings, particularly on your face, ears, shoulders, hands, and back. If recognized early on you can easily prevent the metastasis of the tumor. Look for rough patches of skin, open sores that are prone to bleeding, or any red, crusted, or scaly patch. If any marks are present see your doctor so they can make an early diagnosis if it is indeed skin cancer. Once diagnosed they can remove the cancer long before it has any chance of spreading. Take special care of your skin, checking for red, scaly patches or sores once a month if you are at risk for squamous cell carcinoma because of a lifetime of sun exposure, fair skin, prior problems with skin cancer, or if you are over fifty. Also, men are two to three times more likely to develop the condition. Even if you have already had squamous cell carcinoma successfully treated in the past, it is possible that a new growth can occur so always be aware of your skin.
Squamous cell carcinoma is not likely to metastasize. If it does however, the disease in many cases is fatal, especially if it moves beyond the lymph nodes. Wear sunblock, stay in the shade, wear a broad-rimmed hat when you are out in the garden for hours, and see your doctor if you see any signs of cancerous growth.
