What are the main skin cancers?

The main types of skin cancer are basal cell carcinoma (BCC), squamous cell carcinoma (SCC), melanoma and Merkel cell carcinoma (MCC). The two main causes of skin cancer are the sun’s harmful ultraviolet (UV) rays and the use of UV tanning beds.

Is squamous or basal cell carcinoma worse?

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.

Is skin cancer sarcoma or carcinoma?

A cancer journey can be overwhelming.

A carcinoma forms in the skin or tissue cells that line the body’s internal organs, such as the kidneys and liver. A sarcoma grows in the body’s connective tissue cells, which include fat, blood vessels, nerves, bones, muscles, deep skin tissues and cartilage.

What is the difference between melanoma and carcinoma?

Melanoma typically begins as a mole and can occur anywhere on the body. Squamous cell carcinoma may appear as a firm red bump, a scaly patch, or open sore, or a wart that may crust or bleed easily. Basal cell carcinoma may appear as a small white or flesh-colored bump that grows slowly and may bleed.

How can you tell the difference between squamous cell carcinoma and actinic keratosis?

The main difference between SCC in situ and AK is that in SCC in situ, the full thickness of the epidermis is involved with atypical proliferation of keratinocytes; whereas, in AK, the atypia is limited to lower levels of the epidermis and not its full thickness.

How do skin cancers start?

Skin cancer occurs when errors (mutations) occur in the DNA of skin cells. The mutations cause the cells to grow out of control and form a mass of cancer cells.
