The American Cancer Society  states that for small squamous cell tumors, the recurrence rate is similar to that for basal cell cancers. The larger types of lesions may be more difficult to treat and more aggressive. They cite a statistic that recurrence rates for large deep tumors may be as high as 50%.

Factors Contributing to Squamous Cell Carcinoma Recurrence:

One contributing factor in developing new squamous cell carcinoma lesions is the location of the first tumor. The Skin Cancer Foundation  warns that squamous cell carcinomas on the nose, ears, and lips are especially prone to recurrence and that these skin areas should be watched carefully after treatment.

Another risk factor for developing multiple squamous cell skin cancers is having actinic keratoses which are pre-cancerous skin lesions said to be a breeding ground for future SCC lesions.

Some research indicates that genetics may also play a part in your risk of developing multiple squamous cell skin cancers especially of the head and neck.

If you have been diagnosed with skin cancer there is always that worry that it may return. In my next post we are going to discuss some preventive strategies to decrease the odds for a recurrence. As always it is best to discuss your skin cancer treatment options and risk for recurrence with your doctor.
