Collagen and Neoplasia
It is difficult to define neoplasia clearly. It can be described as a progressive accumulation of pathological tissue. The overgrowth of the neoplastic tissue is not limited by the normal regulatory processes controlling tissue regeneration and occurs also when the unknown stimulating factor is removed. Traditionally, neoplasms are classified into malignant and benign tumors. The growth of the benign form is limited to one location as it does not metastasize. Malignant tumors grow very fast and produce distant foci of neoplasia, i.e., metastases (Wieczorek 1981).
