Keratosis is the medical term for the extra growth on the skin of its inherent protein named keratin. Have you ever had skin lesions? Have you felt the horror that comes with uncovering what lesion it is? Did you ever contemplate that instead of being a rash or insect bite, it might eventually develop to a more threatening disease say for example skin cancer? All you have to do is stop worrying and start gathering information about what your skin problem might be. Since you already have the depiction of the lesion on your skin, it is now time to take advantage of books and internet. But if a trustworthy medical book or internet source suggests it is already a symptom of a far more threatening disease, consult a doctor at once.
Now, we will talk about one type of skin lesion – seborrheic keratosis. It usually varies from yellow, to brown and to black, in color. You can find its lesions to be either flat or lifted above the surface of the skin – which is the case most of the time. There is no one constant size for it can be really small, it can be of average size or it can be peculiarly large. Its shape is either round or oblong. It often appears like a wart but is very dissimilar from it. Though some may present on the skin singled-out, they usually appear in collective groups or batches. For its location, it usually chooses the truck, both anterior and posterior, though they can appear anywhere else in the body. But if someone asks what makes this lesion stand out, the answer is its slippery or oily appearance. And you would be content to know that pain is not a symptom of this type of keratosis. However, if it becomes irritated, there could be inflammation which causes the lesion to become red, warm, edematous, painful and sometimes, bleeding and darkening of its color. As you have noticed, there is nothing to worry about or is there?
I think most of you maybe thought, “Isn’t this a type of skin cancer?” Skin cancer is apparently the most common type of cancer. One out of eight Americans acquires skin cancer. But because the skin is easily available for inspection, its early detection is not a problem. Therefore, it is also the type of cancer that is most successfully treated. The three types of skin cancer whose basis of naming is based on the cells affected will be discussed in the next sentences. The most widespread skin cancer is the basal cell carcinoma (BCC). Even though malignant, basal cell carcinoma grows very slowly and does not always metastasize. Initially, a small, translucent nodule appears. Eventually, it undergoes central ulceration as it grows further. Following basal cell carcinoma in incidence is the squamous cell carcinoma. Unlike basal cell carcinoma, squamous cell carcinoma is more dangerous for it grows and spreads quickly; it is also firmer and redder than the basal cell carcinoma. Of couse, we must not set aside the third type, malignant melanoma which is the most fatal type of skin cancer. Its characteristics can be described using the mnemonic ABCDE. It is asymmetric, its borders are irregular, its color varies, its diameter is greater than 6 millimeters and it is elevated.
Now, we can respond the question whether it is precancerous or not. In contrast with actinic keratosis which eventually leads to squamous cell carcinoma, seborrheic keratosis is not a/an precursor of skin cancer. It is indeed a benign skin tumor. You only have to worry about the lesser problems, namely, disfigurement of your physical appearance and possible irritation of the lesion.
