Expert Solution

start in basement membrane of tissue.
Less differentiated and have lost the ability to control cell proliferation and differentiation. Grow rapidly, invade and infiltrate nearby tissue and spread to other parts of the body. Evade apoptosis and margins are not clearly separated from normal surrounding tissue
Composed of well-differentiated cells resembling the cell of origin but have lost the ability to control cell proliferation. Grow by expansion and remain localized. Do not have the capacity to infiltrate, invade, or metastasize to distant sites.
Cancer cells divide very rapidly because they have a tendency to spread once they enter the bloodstream or lymph vessels.
Malignant tumors can invade and destroy healthy tissue and spread to other parts of the body through the Blood and lymph system.
Metastasis is the spread of cancer cells from the primary site of tumor development to lymph nodes and distant sites. Metastatic cancer cells are invasive due to loss of cell-cell adhesion and increased motility
Secondary tumor looks like primary tumor
Primary tumor: original tumor
Secondary tumor: where the tumor spreads to
Chemotherapy, radiation, and surgery
prevents blood vessel growth, Stops cell division/replication process, Causes spontaneous cell death & Creates a non dividing cell by alteringcell structure
mistake in meiosis cause chromosomal non-disjunction and syndrome
mistake during meiosis leads to mutations in gametes.
Down syndrome
Improper separation of homologous chromosomes or sister chromatids during cell division.
To develop autism and Alzheimer’s later.
Martin-Bell syndrome
Klinefelter syndrome

Cancer cells from a person suffering from malignant melanoma are analyzed and found to have an elevated ability to bind to laminin; they also secrete much higher than normal levels of a certain proteolytic enzyme activity. How would these differences from normal, control cells promote metastasis of these cancer cells?
