4 warning signs of skin cancer

Unusual changes in the skin can be a warning sign of skin cancer. Therefore, you need to recognize them early so that you can take timely preventive or treatment measures.

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

Dr. Debra Wattenberg, a dermatologist in New York, also recommends checking different areas of skin on your body, even in places you least expect, such as the scalp, eyelids, between your fingers and toes, or the skin behind your ears.

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

Ugly moles

Pay attention to any moles that suddenly appear alone and have a different shape from the others on your body. Having more moles isn't necessarily a bad thing, but if they have unusual shapes, you should probably be cautious.

Dr. Sapna Patel, a melanoma researcher in Houston, USA, says that melanoma is the second most common malignant tumor in the world. Its sign can be the appearance of a mole in the skin around the eyes. You can only check for it by seeing a doctor.

Additionally, there's nothing to worry about if you've had moles on your palms or soles of your feet since childhood, but if more have recently appeared, you should probably get them checked out.

Finally, if after you have a mole removed you notice any unusual changes in the pigmentation of the scar, or if you still feel pain after several days, be careful.

Dark spots on fingernails

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

The skin has dark spots that persist for a long time.

If dark spots suddenly appear on your skin and don't fade after more than four weeks, it's very likely that you're not just suffering from sunburn or melasma, but that the underlying cause is skin cancer. In this case, the skin pigments are damaged, leading to changes in skin color, indicating that the skin is no longer healthy.

Acne that doesn't heal

Basal cell or shell-cell skin cancer can manifest as persistent acne-like lesions that last for days without healing, may contain pus, and recur repeatedly.
