How to Recognize a Melanoma
Melanoma is the most serious type of skin cancer
because, except for certain rare forms of cancer, it can spread
to the lymph nodes and penetrate the internal
organs. It is estimated that it accounts for 77% of deaths related to skin
cancer.
Dermatologists believe that deaths from melanoma
can be dramatically reduced if it was recognized early. There are different
types of melanoma; the four most common types account for almost 100% of
diagnosed cases.
Four Types of Melanoma:
- Superficial Spreading (70% of diagnosed melanoma)
This type of melanoma can occur at any age. It is
the leading cause of skin cancer death among young adults. Superficial spreading
melanoma usually starts first in the legs for females. For males, it is likely
to develop first between the pelvis and the neck. However, this does not
necessary mean that males won’t get it on their legs or that females won't get
it on on their trunks because superficial spreading melanoma can occur at any
skin surface.
- Nodular (around 15% of diagnosed melanoma)
Nodular melanoma is very aggressive. It can occur
at any age and the incidence of this condition is higher among males. Nodular
melanoma can appear anywhere on the skin surface. It differs from other types of
melanoma because it tends to grow in thickness rather than in diameter. It may
not have a visible stage of growth and it may arise from an existing mole or a
spot where lesions did not exist.
- Lentigo Maligna (10% of diagnosed melanoma)
People are most vulnerable to lentigo maligna
melanoma after they reach middle-age. This condition usually occurs on
sun-damaged skin on the face. It can be mistaken as a sun spot at its earliest
stages and can go undetected for years.
- Acral Lentiginous (5% of diagnosed melanoma)
Occurring most frequently among the middle-aged and
the elderly, this melanoma is usually mistaken as a sun spot during its most
treatable stage as well. Acral lentiginous is the most common type of melanoma
among Asians and people with darker skin types.
As you can see, two types of melanoma can be traced
directly to sun exposure. To minimize this risk, it may be a good idea to use
tanning beds if you simply cannot go without a tan. Generally, UV exposure is
lower in tanning beds as opposed to sun bathing.
