Chemotherapy is medicine(s) used to kill cancer cells. It is toxic to fast-growing cancer cells. However, it can also affect fast-growing health cells, like blood cells.
Reasons for Procedure
It may be the main treatment or part of an overall plan. It can be used to:
- Cure certain cancers
- Lower the chance of cancer coming back after it has been removed through surgery
- Stop the growth of cancers that can not be removed
- Reduce the size of tumors before surgery
- Attack cancer that has spread to other parts of the body
- Shrink tumors that are causing problems
The medicine attacks fast-growing cells. It can also hurt healthy cells. This can cause side effects. Side effects vary. It depends on the type of medicine and which healthy cells are affected.
Damage to healthy cells that line the mouth, stomach, and intestines can cause:
Healthy blood cells can be damaged. Damage to blood cells can lead to:
- Anemia —low red blood cell count
- Weakened immune system with a higher risk of infections
- Easy bruising and bleeding
Damage to healthy cells at the root of hairs can cause hair loss .
