How does chemotherapy work?

 

How does chemotherapy work?

Depending on the substance, chemotherapy destroys rapidly dividing cells in a variety of ways. Many chemotherapy treatments have been created to target the diverse growth patterns of the many types of malignancies since they all develop differently. Each medication functions differently and is most effective at a certain stage of the targeted cell’s life cycle. For instance, several chemotherapy medications function by:

  • Damaging DNA
  • Preventing cells from dividing
  • Disrupting cellular metabolism or other critical functions

Over 50 chemotherapy medications are frequently employed. Examples of certain chemotherapy medications and their many names are shown in the table below. It covers numerous adverse effects and identifies some of the cancer types they are used to treat, but not necessarily all of them. After receiving chemotherapy, side symptoms may appear immediately (within days or weeks) or months or years afterwards. The list of adverse effects that is presented below is not all-inclusive. There could be further adverse effects.

Each person’s medical history, diagnosis, and response to treatment are unique; thus, are they. There may be severe, minor, or no side effects. Before the start of the therapy, make sure to go over any and all potential side effects with your cancer care team.
