Superficial spreading melanoma
Superficial Spreading Melanoma
Superficial spreading melanoma (pronunciation: soo-per-FISH-ul SPRED-ing mel-uh-NOH-muh) is the most common type of melanoma, a serious form of skin cancer.
Etymology
The term "superficial spreading melanoma" is derived from its characteristic growth pattern. The word "superficial" refers to the initial horizontal growth phase on the surface of the skin, "spreading" indicates the expansive nature of this growth, and "melanoma" is a type of cancer that develops from the pigment-containing cells known as melanocytes.
Definition
Superficial spreading melanoma is a subtype of melanoma that initially grows horizontally across the surface of the skin before penetrating more deeply. It is characterized by its irregular shape, varied coloration, and often larger size.
Symptoms
The primary symptom of superficial spreading melanoma is a change in the appearance of a mole or the development of a new pigmented or unusual-looking growth on the skin. This may include changes in size, shape, color, or texture.
Diagnosis
Diagnosis of superficial spreading melanoma typically involves a skin examination, a review of the patient's medical history, and a biopsy of the suspicious lesion.
Treatment
Treatment options for superficial spreading melanoma may include surgery, radiation therapy, chemotherapy, immunotherapy, or targeted therapy, depending on the stage and location of the cancer.
Prognosis
The prognosis for superficial spreading melanoma varies greatly depending on the stage at diagnosis, with early detection greatly improving the chances of survival.
