Talc Talc Talc or talcum is a clay mineral composed of hydrated magnesium silicate with the chemical formula HMg(SiO) or MgSiO(OH). In loose form, it is (in ratio with or without corn starch) one of the most widely used substances known as baby powder. It occurs as foliated to fibrous masses, and in an exceptionally rare crystal form. It has a perfect basal cleavage, and the folia are not elastic, although slightly flexible. The Mohs scale of mineral hardness, based on scratch hardness comparison, defines value 1 as the hardness of talc. Talc can easily be scratched by a fingernail. Talc
Mohs surgery by ease of hemostasis is weighed against the risk of stopping anticoagulants; and it is generally preferred to continue anticoagulants. Few specialists dispute the cure rate for Mohs, especially pathologists familiar with the procedure. Extensive studies performed by Mohs involving thousands of patients with both fixed tissue and fresh tissue cases have been reported in the literature. Other surgeons repeated the studies with also thousands of cases, with nearly the same results. Clinical 5 year cure rates with Mohs surgery: These are only a small number of cases reported by Mohs, and numerous other articles by other authors have shown
