Melanomas Lymphomas Sarcomas Carcinomas
Yes. Melanomas are the leading cause of death from skin disease.
Malignant melanomas
The four classes of malignant tumors go by the name of carcinoma, lymphoma, sarcomas, and melanomas. It is a potentially life-threatening mass of cancerous cells.
Stage I and stage II have no involvement of the regional lymph nodes and are thus localized to the site of origin.
One suggestion as of late 2003 is that the genes ordinarily responsible for apoptosis (cell self-destruction) do not function normally in melanomas.
Stage III is defined by the presence of in-transit or regional nodal metastasis or both. Stage IV is defined by the presence of distant metastasis.
These are: superficial spreading, nodular, lentigo maligna, and acral lentiginous melanomas, accounting for 70%, 15% to 30%, 4% to 10%, and 2% to 8% of cases, respectively.
No, not all gray horses will have cancer. However, gray horses are strongly predisposed to developing malignant melanomas, an aggressive cancer starting from the pigment-producing cells of the skin.
A small percentage of melanomas arise within burn scar tissue. As of 2003, researchers do not fully understand the relationship between deep burns and an increased risk of skin cancer.
The doctor may also use a dermatoscope to examine the mole prior to removal. The dermatoscope, which can be used to distinguish between benign moles and melanomas, is an instrument that resembles an ophthalmoscope.
One can find pictures of Melanomas on various websites like Mayoclinic and Melanoma. Both websites offer a great amount of pictures of Melanomas and can be downloaded for free.
