Melanoma is the most dangerous type of skin cancer; it develops from the melanin-producing cells known as melanocytes. [1] It typically occurs in the skin, but may rarely occur in the mouth, intestines, or eye (uveal melanoma). [1] [2] In women, melanomas most commonly occur on the legs; while in men, on the back.

Melanoma: Localized melanoma in AYAs may have clinically different features than in older adults. Adolescents and young adults also tend to have higher stages of melanoma at diagnosis. Younger age at diagnosis and high mitotic rate may correlate with a greater likelihood of metastasis to the lymph nodes. [15]
Childhood cancer is cancer in a child. About 80% of childhood cancer cases in high-income countries can be successfully treated via modern medical treatments and optimal patient care. [2] [3] However, only about 10% of children diagnosed with cancer reside in high-income countries where the necessary treatments and care is available.
Skin cancer is the most common form of cancer, globally accounting for at least 40% of cancer cases. [5] [20] The most common type is nonmelanoma skin cancer, which occurs in at least 2–3 million people per year. [6] [21] This is a rough estimate; good statistics are not kept. [1]
Evolution of a 4 mm nodular melanoma. Nodular melanoma (NM) is the most aggressive form of melanoma. [1] It tends to grow more rapidly in thickness (vertically penetrate the skin) than in diameter compared to other melanoma subtypes. [2] Instead of arising from a pre-existing mole, it may appear in a spot where a lesion did not previously exist.

In 2023, according to the Skin Cancer Foundation, 97,610 cases of invasive melanoma will be diagnosed in the United States; of those, 58,120 will be in men, and 39,490 in women. Of the 7,990 ...
INK4A, also known as p16, is a tumor suppressor gene and is found to have hypermethylated promoter regions in 10- 20% of melanoma cells and is involved in 40- 87% of gene alterations in melanoma cases (Gonzalgo et al., 1997). This means that 10- 20% of the time there is an epigenetic change in the INK4A gene, and 40- 87% of the time there is a ...
