Melanoma is often called “the most serious skin cancer” because it has a tendency to spread. Melanoma can develop within a mole that you already have on your skin or appear suddenly as a dark spot on the skin that looks different from the rest.
Which of the following is a serious form of skin cancer?
There are scattered cells called melanocytes where the epidermis meets the dermis. These cells produce the pigment melanin, which gives skin its color. Melanoma starts in melanocytes, and it is the most serious type of skin cancer.
Is melanoma the most serious form of skin cancer?
Melanoma, the most serious type of skin cancer, develops in the cells (melanocytes) that produce melanin — the pigment that gives your skin its color. Melanoma can also form in your eyes and, rarely, inside your body, such as in your nose or throat.
What is most common type of skin cancer?
Basal and squamous cell carcinomas are the two most common types of skin cancer. They begin in the basal and squamous layers of the skin, respectively. Melanoma, the third most common type of skin cancer, begins in the melanocytes.
What are 3 main types of skin cancer?
But this common form of cancer can also occur on areas of your skin not ordinarily exposed to sunlight. There are three major types of skin cancer — basal cell carcinoma, squamous cell carcinoma and melanoma.
What are the causes of skin cancer?
The two main causes of skin cancer are the sun’s harmful ultraviolet (UV) rays and the use of UV tanning beds.
Is melanoma a skin cancer?
Melanoma is a type of skin cancer that develops when melanocytes (the cells that give the skin its tan or brown color) start to grow out of control. Cancer starts when cells in the body begin to grow out of control. Cells in nearly any part of the body can become cancer, and can then spread to other areas of the body.
Which skin cancer is most common and least common?
Basal cell carcinoma (BCC)
This is the most common but least dangerous form of skin cancer. It grows slowly, usually on the head, neck and upper torso. It may appear as a lump or dry, scaly area.
What is least common form of skin cancer?
Melanoma skin cancer
Least common but most serious form of skin cancer. Can appear in a new or an existing spot, freckle or mole that changes colour, size or shape. Grows over weeks to months anywhere on the body (not just areas that get lots of sun). If untreated, cancer cells can spread to other parts of the body.
Which of the following is the most common place for basal cell carcinoma?
Basal cell carcinoma occurs most often on areas of the skin that are exposed to the sun, such as your head and neck.
What are the levels of skin cancer?
There are three major types of skin cancers: basal cell carcinoma (BCC), squamous cell carcinoma (SCC), and melanoma. The first two skin cancers are grouped together as non-melanoma skin cancers. Other unusual types of skin cancer include Merkel cell tumors and dermatofibrosarcoma protruberans.
