Skin cancer — the abnormal growth of skin cells — most often develops on skin exposed to the sun. 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 5 types of skin cancer?
Types of skin cancer
- Basal cell carcinoma. Basal cells are the round cells found in the lower epidermis. …
- Squamous cell carcinoma. Most of the epidermis is made up of flat, scale-like cells called squamous cells. …
- Merkel cell cancer. Merkel cell cancer is a highly aggressive, or fast-growing, rare cancer. …
What is the difference between basal cell carcinoma and melanoma?
Melanoma is a serious form of skin cancer that begins in cells known as melanocytes. While it is less common than basal cell carcinoma (BCC) and squamous cell carcinoma (SCC), melanoma is more dangerous because of its ability to spread to other organs more rapidly if it is not treated at an early stage.
What are the common types of skin cancer?
Basal and squamous cell skin cancers are the most common types of skin cancer. They start in the top layer of skin (the epidermis), and are often related to sun exposure.
What type of skin cancer is most common?
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.
How can you identify skin cancer?
Raised reddish patches that might be itchy. Small translucent, shiny, pearly bumps that are pink or red and which might have blue, brown, or black areas. Pink growths with raised edges and a lower area in their center, which might have abnormal blood vessels spreading out like the spokes of a wheel.
What is invasive skin cancer?
Invasive – An invasive skin cancer has penetrated beyond the epidermis into the dermis and is growing into surrounding, healthy tissue. Invasive skin cancers should be removed promptly, and tests need to be done to see if further treatments are called for.
What are the worst skin cancers?
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. Early diagnosis and treatment are crucial.
What’s worse basal cell or squamous?
Though not as common as basal cell (about one million new cases a year), squamous cell is more serious because it is likely to spread (metastasize). Treated early, the cure rate is over 90%, but metastases occur in 1%–5% of cases. After it has metastasized, it’s very difficult to treat.
How do I know if I have basal cell or squamous cell carcinoma?
Basal cell carcinoma most commonly appears as a pearly white, dome-shaped papule with prominent telangiectatic surface vessels. Squamous cell carcinoma most commonly appears as a firm, smooth, or hyperkeratotic papule or plaque, often with central ulceration.
Are skin cancers itchy?
Skin cancers often don’t cause bothersome symptoms until they have grown quite large. Then they may itch, bleed, or even hurt. But typically they can be seen or felt long before they reach this point.
What does early signs of melanoma look like?
The first sign of melanoma is often a mole that changes size, shape or color. This melanoma shows color variations and an irregular border, both of which are melanoma warning signs. Melanomas can develop anywhere on your body.
Can you feel skin cancer?
First thing’s first — no, you cannot feel skin cancer, at least not in the same way you would a stomach ache or something like that. What you can feel, however, are some of the warning signs and symptoms that skin cancer might bring with it like itchiness, burning, and so on.
What is the most treatable skin cancer?
The earliest form of melanoma (considered stage 0), it is the easiest to treat and almost always curable.
Which skin cancer is the most common but least malignant?
Basal cell carcinoma
Most common form of skin cancer but the least dangerous. Appear as round or flattened lump or scaly spots.
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.
