Skin cancer is the most common cancer worldwide. In Germany alone, around 21,000 people contract black skin cancer every year, 3,000 die from it and the numbers are rising. To this end, skin cancer has long ceased to be a disease that only affects the elderly. ⅕ of sufferers are under 50 years old. Fortunately, black skin cancer is treatable if it is detected early.
Once malignant melanoma has been diagnosed and removed by biopsy, the disease is far from written off. Risk-adapted follow-up care should take place over a period of 10 years. Here, the patient, under medical guidance, is considered an essential part of the follow-up and thus plays an important role in the early detection of recurrences or second melanomas.

Once a patient has been diagnosed with black skin cancer, the doctor creates an account for his patient and enters initial to-dos into the app. The health insurance company then sends the device to the patient. To access his already created account, the patient enters a code in the app that he has previously received from the doctor.

From this point on, the patient is responsible for documenting abnormal areas. Over a period of months, patients enter new images of suspicious lesions into the app using the scanner. This runs over intervals specified by the doctor. These images can then be compared. If there are any abnormalities, for example in the form of a change in size or color, the doctor receives a data package consisting of a short questionnaire answered by the patient and the comparison. The doctor can now evaluate this and, if necessary, arrange an appointment for removal.

Image
With the Melafy device, images are taken under the same conditions. Same exposure, same distance, same sharpness. This allows a clean comparison of two images. In this way, growth or color changes can be easily identified. Currently, a suspicious mole is usually photographed with a smartphone. This results in many blurred images, with different exposures. These images are also valuable for future A.I. systems.
Documentation
Since follow-up care runs over several years, some images accumulate. With the clean documentation of the image data and the associated information, quick and traceable conclusions can be drawn.
Early detection
Once skin cancer has been detected, the probability of a second melanoma or a recurrence increases enormously. Through the simple and short questionnaire before image acquisition and the subsequent image comparison, potentially recurring skin cancer can be identified more quickly.
Time/Effort
Doctors never have time. Neither do patients, although the term can be derived from the word "patience." Doctors can work off a lot of tasks via the app, even in their home offices. Direct doctor-patient contact also allows appointment triage to be bypassed to justify important appointments. This minimizes waiting times and allows doctors to complete repetitive tasks faster.
