4 warning signs of skin cancer

Unusual changes in the skin can be warning signs of skin cancer. Therefore, you need to recognize them early to have timely prevention or treatment measures.

American dermatologist Julie Karen shared: "We often ignore strange moles and marks on the skin, but in fact they are more dangerous than we think."

New York dermatologist Dr. Debra Wattenberg also recommends checking different areas of your body, including places you least expect, like your scalp, eyelids, between your fingers and toes, or behind your ears.

Here are the warning signs of skin cancer you should definitely pay attention to:

'Ugly' moles

Pay attention to moles that suddenly appear alone and are shaped differently from the other moles on your body. Having extra moles is not a bad thing, but if they are oddly shaped, you should probably be careful.

Dr. Sapna Patel, a melanoma researcher in Houston (USA), said that the second most common malignant tumor in the world is melanoma. Its sign can be the appearance of a mole in the eye area. You can only check it by going to the doctor.

Also, it's not a big deal if you've had moles on your palms or feet since childhood, but if you've recently developed new ones, you should probably get them checked out.

Finally, if after you remove a mole you notice strange changes in the pigmentation outside the scar, or it still feels painful after several days, be careful.

Dark spots on nails

When you notice a black or brown spot on your nail, you may mistake it for a scratch or bleeding in the nail. However, if it doesn't go away, it could be a sign of squamous cell skin cancer.

Skin with dark spots for a long time

If your skin suddenly develops dark spots and after more than 4 weeks, these spots do not fade, it is very likely that you are not only suffering from sunburn or melasma, but the underlying cause is skin cancer. At this time, the skin pigments are damaged, leading to a change in skin color, proving that the skin is no longer healthy.

Acne that won't heal

Basal cell or squamous cell skin cancer can manifest as a persistent pimple that does not heal for days, may contain pus, and recurs repeatedly.
