The chemotherapy drug 5-FU can be toxic to some people with cancer. A quick, cheap test can show if chemo is safe for a patient, but few doctors order it. A quick, cheap test could protect against ...
These agents protect specific body parts from harmful anti-cancer treatments that could potentially cause permanent damage to important bodily tissues. Chemo-protective agents have only recently been introduced as a factor involved with chemotherapy with the intent to assist those cancer patients that require treatment, which as an result ...
As most chemotherapy drugs kill cancer cells in this manner, defective apoptosis allows survival of these cells, making them resistant. Many chemotherapy drugs also cause DNA damage, which can be repaired by enzymes in the cell that carry out DNA repair. Upregulation of these genes can overcome the DNA damage and prevent the induction of apoptosis.
Instead, the drugs affect new blood cells that are being made by the bone marrow. [4] When myelosuppression is severe, it is called myeloablation. [5] Many other drugs including common antibiotics may cause bone marrow suppression. Unlike chemotherapy the effects may not be due to direct destruction of stem cells but the results may be equally ...

[9] [10] These effects can impair a chemotherapy patient's ability to understand and make decisions regarding treatment, perform in school or employment and can reduce quality of life. [10]

These drugs disrupt microtubules, which are structures that pull the chromosomes apart when a cell divides. Mitotic inhibitors are used in cancer treatment, because cancer cells are able to grow through continuous division that eventually spread through the body (metastasize). Thus, cancer cells are more sensitive to inhibition of mitosis than ...
