What does the ABCD rule stand for?

The ABCDE rule for skin cancer is a handy acronym that can help you identify potential skin cancers. The letters stand for “Asymmetrical, Border, Color, Diameter, Evolving.” A new or changing spot or mole on your skin may be a sign of cancer. When in doubt, it’s best to have a doctor check it out.

What are the Abcde signs of skin cancer?

The “ABCDE” rule is helpful in remembering the warning signs of melanoma:

  • Asymmetry. The shape of one-half of the mole does not match the other.
  • Border. The edges are ragged, notched, uneven, or blurred.
  • Color. Shades of black, brown, and tan may be present.
  • Diameter.
  • Evolving.

What are the Abcds of melanoma?

The ABCDEs of melanoma skin cancer are:

  • Asymmetry. One half doesn’t match the appearance of the other half.
  • Border irregularity. The edges are ragged, notched, or blurred.
  • Colour. The colour (pigmentation) is not uniform.
  • Diameter.
  • Evolution.

How is melanoma Abcde detected?

The ABCDEs of melanoma

  1. A is for Asymmetry. Most melanomas are asymmetrical.
  2. B is for Border. Melanoma borders tend to be uneven and may have scalloped or notched edges, while common moles tend to have smoother, more even borders.
  3. C is for Color.
  4. D is for Diameter or Dark.
  5. E is for Evolving.

What is a Macule skin lesion?

Macules are flat, nonpalpable lesions usually < 10 mm in diameter. Macules represent a change in color and are not raised or depressed compared to the skin surface. A patch is a large macule. Examples include freckles, flat moles, tattoos, and port-wine stains.

How the ABCD E’s method is valuable in early melanoma detection?

The Skin Cancer Foundation and the American Academy of Dermatology recommend using the ABCD method (see photos above) to help detect melanoma: A (most early melanomas are asymmetrical); B (borders of melanomas are uneven); C (color; varied shades of brown, tan, or black are often the first sign of melanoma); and D ( …

What are the two most common premalignant skin tumors?

AK (71.2% of all premalignancies) and BD (24.6%) were the two most common premalignant skin lesions whereas for skin cancers, BCC (46.2% of all malignancies), SCC (19.1%), metastatic cancer and melanoma (7.1%) were common in a decreasing order.
