It depends on the atom. If you know the atomic number, that's how many protons are in the nucleus. For example, an oxygen atom has 8 protons, iron has 26, and uranium has 92. Views Â· 1 Upvote.
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. Unlike basal-cell carcinoma (BCC), squamous-cell carcinoma (SCC) has a substantial risk of metastasis. 2  Risk of metastasis is higher in SCC arising in scars, on the lower lips or mucosa, and occurring in immunosuppressed patients.
The earliest form of squamous cell cancer is called carcinoma in situ, meaning that the cancer cells are present only in the outer layer of cells called the epithelium. This is different from invasive squamous cell carcinoma, where the cancer cells have grown into deeper layers of the oral cavity or oropharynx.
