melanoma :
It's the most dangerous of the potentially fatal skin cancers resulting from melanocytes, which give our skin its color, that pigment is melanin. In general, it's some form of overexposure to ultraviolet radiation whether that radiation emanates from the sun or one of those magic tanning beds that will cause DNA damage to your skin cells. Such signs and symptoms encompass new moles or some changes in the previous existing moles related to their size and color, shape, and bleeding. If any melanoma remains untreated, it spreads incredibly within the body . So it becomes pretty important to detect it as early as possible. The diagnosis is commonly confirmed through a skin biopsy. Infection of the lymph nodes often occurs, but cure rates can be improved depending on the stage of this cancer through intervention methods which may include surgical removal of the tumor, immunotherapy, targeted therapy, or even radiation therapy. Preventive measures include a regular check on the skin and avoiding exposure to the sun in areas of damaged skin. With early intervention, the prognosis for the patient with melanoma can greatly be improved.
