Alcohol withdrawal is different from withdrawal from most other drugs because alcohol withdrawal can be deadly. The only drugs as likely to cause death from withdrawal as alcohol are the benzodiazepines. Heroin withdrawal rarely if ever kills anyone. But untreated major alcohol withdrawal can kill one person in three.
Squamous-cell carcinoma or squamous-cell cancer (SCC or SqCC) is a cancer of a kind of epithelial cell, the squamous cell.These cells are the main part of the epidermis of the skin, and this cancer is one of the major forms of skin cancer.CC is still sometimes referred to as  epidermoid carcinoma  and  squamous-cell epithelioma , though the use of these terms has decreased. SCC typically initially occurs in the sixth decade of life (the 50s), but is most common in the eighth decade (the 70s). It is twice as prevalent in men as in women.
Squamous cell carcinoma accounts for roughly 20% of all cases of non-melanoma skin cancer. Squamous cell carcinoma commonly involves the head or neck. The tumor may appear as a red bump or as a rough or scaly area on the skin. Squamous cell carcinoma is more likely than basal cell carcinoma to spread to lymph nodes or distant parts of the body, though this happens infrequently. Treatment of squamous cell carcinoma often involves surgery to remove the cancer. The prognosis for cutaneous squamous cell carcinoma (CSCC) is usually good, but some patients have poor outcomes. To identify factors associated with poor outcomes, researchers conducted a 10-year retrospective cohort study that included 985 patients and 1,832 tumors.
