Actinic Keratosis, also known as solar keratosis or AKs, is an early sign of skin cancer. Actinic Keratosis is the product of prolonged sun exposure throughout time. AKs is not the result of a single case of bad sunburn; rather, it is produced by cumulative sun exposure.

AKs that appear on the upper or lower lip is called actinic cheilitis and will make you lips feel dry, scaly and start to crack.

It is lucky that most people are able to treat their Actinic Keratoses before it transforms into far more dangerous squamous cell carinomas- a high-risk, life-threatening form of skin cancer. In most instances, treatment of AKs prior to this transformation is an effective means of preventing further health problems.

Home remedies won't cure your skin cancer and will waste valuable time that could have been spent on an actual treatment.

6. Treat Actinic Keratosis early to prevent skin cancers
Left untreated, AKs can develop into Squamous cell carcinoma, an invasive form of skin cancer. Unfortunately, the transformation process of AKs to squamous cell carcinoma is not entirely known. What is known for certain is that having AKs gives you an increased risk of As a result, medical professionals recommend any individual experiencing AKs to treat the condition as soon as possible.
While self-checks are great for spotting potential signs and symptoms, only a professional skin check can accurately determine where a skin condition is harmless or something to worry about. Skin checks take between 15-30 minutes. You'll be asked to undress to your underwear so your doctors can examine your entire body. In most cases, nothing it found, and you get the gift of peace of mind. However, when the doctor does find something, it can literally be a life-saving discovery. So, if you have any skin damage, skin growths, lesions or moles you're unsure about, get them checked as soon as possible.
7. Actinic Keratosis on the head or neck may be more serious
Scaly patches or sun damaged skin on your head, ears, lips or neck need to be taken more seriously because skin cancer is statistically more likely to occur in these places. This is especially the case with basal cell carcinoma and squamous cell carcinoma. While it is not impossible for these issues to occur elsewhere, the fact that they come as a result of overexposure to uv light means sun exposed areas are statistically more likely to be areas of concern. If you have a concern about a skin patch, mark or mole anywhere on your body, you should have it looked at.
