a malignant tumor of potentially unlimited growth that expands locally and systemically
an ordered sequence of events in the life of a eukaryotic cell, from its origin in the division of a parent cell until its own division into two.
process of programmed cell death
A gene having the potential to cause a normal cell to become cancerous.
The removal and examination of tissue, cells, or fluids from the living body.
A cancer derived from bone or containing bone tissue.
Normal cellular genes that regulate cell proliferation and differentiation that can become oncogenes.
genes that normally produce proteins that inhibit cell division
tumor suppression genes
If you were inspecting tissue taken from a tumor biopsy, what characteristics would you look for that would indicate the presence of cancer cells?
shape, size and nucleus abnormalities
Describe the genetic mutations that you think occurred in the cancer cells that were responsible for the phenotypic differences between the normal and cancer cells you observed.
proto- oncogenes to oncogenes and mutations in gene tumor supression genes
Why is cancer such a difficult disease to study?
many different types and causes
How can studying genes give us more information about cancer?
genes are the cause of cancer. If we can learn more about the mutations in the genes then we can learn more about the cancer too. It is also possible thatif the genes are fixed then the cancer could be cured
characterstics of cancer cells
In what ways are diagnostic imaging technologies used to diagnose and treat disorders?
