loss of growth control
spectrum of neoplasms
benign - intermediate - malignant
malignant refers to
the ability of the tumor to metastasize
very malignant tumors
small cell carcinoma in the lung
benign tumor ex
uterine fibroids - will not metastasize
intermediate tumors
some kill you some don_t_these are still slow growing and invasive
gold standard of malignancy
***capacity to metastasize, local invasion, dedifferentiation/anaplasia, rapid rate of growth, uniformly fatal if untreated, exceptions exist
benign tumors tend to
grow and push the surrounding tissue
malignant tumors tend to
invades through the tissue and can see it in a biopsy
dedifferentiation of malignant tumors
somewhat, not totally_.used terms like well differentiated or moderate differentiation to “grade” the tumors
