The most dangerous form of skin cancer, these cancerous growths develop when unrepaired DNA damage to skin cells (most often caused by ultraviolet radiation from sunshine or tanning beds) triggers mutations (genetic defects) that lead the skin cells to multiply rapidly and form malignant tumors. These tumors originate in the pigment-producing melanocytes in the basal layer of the epidermis. Melanomas often resemble moles; some develop from moles. The majority of melanomas are black or brown, but they can also be skin-colored, pink, red, purple, blue or white. Melanoma is caused mainly by intense, occasional UV exposure (frequently leading to sunburn), especially in those who are genetically predisposed to the disease. Melanoma kills an estimated 8,790 people in the US annually.


If melanoma is recognized and treated early, it is almost always curable, but if it is not, the cancer can advance and spread to other parts of the body, where it becomes hard to treat and can be fatal. While it is not the most common of the skin cancers, it causes the most deaths.


Family History

 

Heredity plays a major role in melanoma. About one in every 10 patients diagnosed with the disease has a family member with a history of melanoma.
 

It is always recommended using a sunscreen with an SPF 15 or higher as one important part of a complete sun protection regimen. Sunscreen alone is not enough, however. Full list of skin cancer prevention tips:
 

  • Seek the shade, especially between 10 AM and 4 PM.

  • Do not burn.

  • Avoid tanning and UV tanning booths.

  • Cover up with clothing, including a broad-brimmed hat and UV-blocking sunglasses.

  • Use a broad spectrum (UVA/UVB) sunscreen with an SPF of 15 or higher every day. For extended outdoor activity, use a water-resistant, broad spectrum (UVA/UVB)sunscreen with an SPF of 30 or higher.

  • Apply of sunscreen to your entire body 30 minutes before going outside. Reapply every two hours or immediately after swimming or excessive sweating.

  • Keep newborns out of the sun. Sunscreens should be used on babies over the age of six months.

  • Examine your skin head-to-toe every month.

  • See your physician every year for a professional skin exam.
     

Warning Signs: The ABCDEs of Melanoma
 

Moles, brown spots and growths on the skin are usually harmless - but not always. Anyone who has more than 100 moles is at greater risk for melanoma. The first signs can appear in one or more atypical moles. Look for the ABCDE signs of melanoma, and if you see one or more, make an appointment with a physician immediately.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Treatment
 

Surgical Excision
 

The first step in treatment is the removal of the melanoma, and the standard method of doing this is by surgical excision (cutting it out). 

Melanoma

E- Evolving

Any change - in size, shape, color, elevation, or another trait, or any new symptom such as bleeding, itching or crusting - points to danger.

D- Diameter
Melanomas usually are larger in diameter than the size of the eraser on your pencil (1/4 inch or 6 mm), but they may sometimes be smaller when first detected.

C- Color

Having a variety of colors is another warning signal. A number of different shades of brown, tan or black could appear. A melanoma may also become red, blue or some other color.

B- Border

The borders of an early melanoma tend to be uneven. The edges may be scalloped or notched.

A - Asymmetry
If you draw a line through this mole, the two halves will not match.
