Cutaneous squamous-cell carcinoma is the second-most common cancer of the skin (after basal-cell carcinoma, but more common than melanoma). It usually occurs in areas exposed to the sun. Sunlight exposure and immunosuppression are risk factors for SCC of the skin, with chronic sun exposure being the strongest environmental risk factor. [26]
Cancer staging can be divided into a clinical stage and a pathologic stage. In the TNM (Tumor, Node, Metastasis) system, clinical stage and pathologic stage are denoted by a small "c" or "p" before the stage (e.g., cT3N1M0 or pT2N0). This staging system is used for most forms of cancer, except brain tumors and hematological malignancies.
Typically, many genetic changes are required before cancer develops. [11] Approximately 5–10% of cancers are due to inherited genetic defects. [12] Cancer can be detected by certain signs and symptoms or screening tests. [2] It is then typically further investigated by medical imaging and confirmed by biopsy. [13]

This skin cancer tends to grow slowly and isn’t life-threatening for most people, but it needs to be treated before it can grow deep and injure nerves and blood vessels, the AAD noted.
Cancer cells often opportunistically switch between different kinds of motion. Some cancer researchers hope to find treatments that can stop or at least slow down the spread of cancer by somehow blocking some necessary step in one or more kinds of motion. [16] [17] All steps of the metastatic cascade involve a number of physical processes.
Triple-negative breast cancer acts aggressively, grows quickly, spreads further and is more likely to return, the American Cancer Society says. It often occurs in women younger than 40, Black ...
