Benign: Sk's are easily confused for skin cancers due to their large size, irregular shape, and being multicolored. A trained dermatologist can easily spot the difference but very confusing for patients and other doctors. People can have hundreds or even thousands of sk's on their body and they are all benign. But having these cover the body may make it difficult to monitor for skin cancers.

Benign: Seborrheic keratosis is not associated with cancer. However some of these lesions can be very difficult to distinguish from cancer, so make sure that you are getting a complete skin exam by and experienced physician.
