Electron transfer is usually difficult to see in the organic. reactant(s) and product(s) in an organic redox reaction. For example the conversion of a 2Â°. alcohol to a ketone (Figure 17.003) is oxidation, but it is not obvious that electron transfer has. occurred by looking at the alcohol and ketone structures. Figure 17.003. This electron transfer is generally visible, however, in the inorganic reagents and products of.
Other lesions, such as basal cell carcinoma, squamous cell carcinoma, melanoma, and Kaposiâs sarcoma are malignant, and early diagnosis and treatment can prevent metastasis, which. can be life threatening. Benign and pre-cancerous lesions.
A-Malignant melanoma, commonly called melanoma, is cancer of the melanocyte cells of the skin. It is an aggressive cancer that requires aggressive therapy to control its spread. Basal cell carcinoma, also known as basal cell epithelioma, is the most common form of skin cancer. It is a slow-growing cancer and seldom metastasizes, but it can grow so large that the entire area of the nose, the lip, or the ear must be removed and reconstructed.
