If actinic keratosis is detected and treated in time, the prognosis is generally good. Otherwise, it can develop into a carcinoma, i.e. a spinalioma or squamous cell carcinoma. It is also possible, for example after treatment with PDT, that the disease will recur (relapse). For this reason, constant follow-up examinations should be carried out.
The most effective prevention has been proven to be the complete avoidance of UV light (maternity leave) with the help of hats, UV-impermeable clothing and sunscreen, as well as adapted leisure behaviour. 25% of actinic keratoses heal even without therapy during UV light parental leave. You should also regularly examine your skin for conspicuous areas and, if possible, have a skin cancer screening performed.
