Which are the symptoms of Skin Cancer?

Symptoms of Skin Cancer

Skin cancer is the most common type of cancer worldwide, and it primarily affects the skin. It occurs when there is an uncontrolled growth of abnormal skin cells. Early detection is crucial for successful treatment, so it is important to be aware of the symptoms of skin cancer. While these symptoms may vary depending on the type and stage of skin cancer, there are some common signs to look out for:

1. Changes in the Skin

One of the first signs of skin cancer is a change in the appearance of the skin. This can include the development of new growths or the alteration of existing moles, freckles, or birthmarks. Pay attention to any changes in size, shape, color, or texture of these skin marks.

2. Moles

Moles are a common type of skin growth, and most of them are harmless. However, certain changes in moles can indicate skin cancer. The ABCDE rule can help identify suspicious moles:

• Asymmetry: One half of the mole does not match the other half.


• Border: The edges of the mole are irregular, blurred, or poorly defined.


• Color: The mole has uneven colors or shades of brown, black, white, red, or blue.


• Diameter: The mole is larger than 6 millimeters in diameter (about the size of a pencil eraser).


• Evolving: The mole is changing in size, shape, or color.

3. Sores or Ulcers

Non-healing sores or ulcers on the skin that persist for more than a few weeks can be a sign of skin cancer. These sores may bleed, ooze, or crust over, and they typically do not heal with normal wound care.

4. Redness or Swelling

Unexplained redness, swelling, or inflammation of the skin can be an indication of skin cancer. This symptom may be accompanied by tenderness or pain in the affected area.

5. Itching or Sensation

Constant itching, tenderness, or pain in a particular area of the skin can be a warning sign of skin cancer. If you notice persistent discomfort, it is important to have it evaluated by a healthcare professional.

6. Bleeding or Crusting

If a skin lesion, mole, or growth bleeds without any apparent cause or crusts over and does not heal, it may be a sign of skin cancer. These symptoms should not be ignored and should be examined by a medical professional.

7. Spots that Look Like Scars

Skin cancer can sometimes appear as flat, white, or waxy spots that resemble scars. These spots may be firm to the touch and have poorly defined borders. If you notice any unusual spots on your skin, it is important to have them checked by a dermatologist.

It is important to note that these symptoms are not exclusive to skin cancer and can be caused by other conditions as well. However, if you notice any of these signs, it is essential to consult a healthcare professional for a proper diagnosis and appropriate treatment.
