Every year there are more warnings about how dangerous the sun is. The number of people suffering from skin cancer is also increasing strangely. The fact is that the sun is becoming more dangerous year by year, especially for young women who further jeopardize their health by exposing themselves to UV rays in tanning beds.

Before surrendering to the sun, it's good to visit a dermatologist who will examine all suspicious pigmented spots. You can also do a lot yourself by taking precise photos of each suspicious spot. Re-photograph these same suspicious spots after 2 to 3 days...

Symmetry
If your spots are increasing symmetrically, you generally don't need to worry. More problematic are spots that spread uncontrollably in all directions or have a distinct direction (line) of expansion. This is definitely a sign to immediately see a dermatologist.

Color and Border
A healthy pigmented spot has even color and a smooth surface. Melanoma can also be recognized by having a darker border, uneven color, and a non-smooth surface (if the surface is rough, it doesn't necessarily mean anything).

Size
Although this rule is not universal, it's still worth considering. Spots smaller than 6 millimeters in diameter are generally not dangerous.

Changes
If a spot remains unchanged after two or three days in the sun (size, color, shape), then you don't need to worry. Just be attentive to any itchiness. It shouldn't occur. Especially avoid scratching until it bleeds, which can be very dangerous.

And one more thing: act responsibly and carefully photograph your body every year. This way you can easily notice any changes, and these photos can be very helpful to the doctor.

And don't forget sunscreen.
