Why are chemotherapeutic drugs generally successful against cancer cells group of answer choices?
Chemo is considered a systemic treatment because the drugs travels throughout the body, and can kill cancer cells that have spread (metastasized) to parts of the body far away from the original (primary) tumor. This makes it different from treatments like surgery and radiation.
Which of the following characteristics are typical of cancer cells?
Cancer cells grow and divide at an abnormally rapid rate, are poorly differentiated, and have abnormal membranes, cytoskeletal proteins, and morphology.
What actually is cancer?
Cancer is a disease caused when cells divide uncontrollably and spread into surrounding tissues. Cancer is caused by changes to DNA. Most cancer-causing DNA changes occur in sections of DNA called genes. These changes are also called genetic changes.
Which of the following is not a type of proto oncogene?
Which of the following is not a type of proto-oncogene? *The gene for p53 encodes a tumor suppressor, not a proto-oncogene.
What are the 5 characteristics of cancer cells?
The malignant cell is characterized by: acceleration of the cell cycle; genomic alterations; invasive growth; increased cell mobility; chemotaxis; changes in the cellular surface; secretion of lytic factors, etc. Morphological and functional characteristics of the malignant cell.
What process is typical of cancer?
Cancer develops when the normal processes that control cell behaviour fail and a rogue cell becomes the progenitor of a group of cells that share its abnormal behaviours or capabilities. This generally results from accumulation of genetic damage in cells over time.
What are three treatments used for cancer patients?
Cancer treatment options include:Surgery. The goal of surgery is to remove the cancer or as much of the cancer as possible.Chemotherapy. Chemotherapy uses drugs to kill cancer cells.Radiation therapy. ... Bone marrow transplant. ... Immunotherapy. ... Hormone therapy. ... Targeted drug therapy. ... Cryoablation.More items...
Why is cancer called cancer?
Origin of the word cancer In Greek, these words refer to a crab, most likely applied to the disease because the finger-like spreading projections from a cancer called to mind the shape of a crab. The Roman physician, Celsus (25 BC - 50 AD), later translated the Greek term into cancer, the Latin word for crab.
Are there treatments for cancer?
The most common treatments are surgery, chemotherapy, and radiation. Other options include targeted therapy, immunotherapy, laser, hormonal therapy, and others. Here is an overview of the different treatments for cancer and how they work. Surgery is a common treatment for many types of cancer.
What is oncogene and proto-oncogene?
An oncogene is a mutated gene that has the potential to cause cancer. Before an oncogene becomes mutated, it is called a proto-oncogene, and it plays a role in regulating normal cell division.
What is a proto-oncogene quizlet?
Proto-oncogenes. A normal gene which, when altered by mutation, becomes an oncogene that can contribute to cancer. Proto-oncogenes may have many different functions in the cell. Some proto-oncogenes provide signals that lead to cell division. Other proto-oncogenes regulate programmed cell death (apoptosis).
Is p53 a proto-oncogene?
The p53 proto-oncogene can act as a suppressor of transformation. Cell 57, 1083–1093 (1989). Funk, W. D., Pak, D. T., et al. A transcriptionally active DNA-binding site for human p53 protein complexes.
