The “normal” cells most commonly affected by chemotherapy are the blood cells, the cells in the mouth, stomach and bowel, and the hair follicles; resulting in low blood counts, mouth sores, nausea, diarrhea, and/or hair loss. Different drugs may affect different parts of the body.
What cells are destroyed in chemotherapy?
Here are five common side effects and why they occur.
Here are some of the main types of healthy cells that chemotherapy impacts:
- red blood cells, white blood cells, and platelets.
- hair cells.
- cells that make up the mucus membranes of the mouth, throat, and digestive system.
What part of the cell does chemotherapy affect?
Chemotherapy damages the genes inside the nucleus of cells. Some drugs damage cells at the point of splitting. Some damage the cells while they’re making copies of all their genes before they split. Chemotherapy is much less likely to damage cells that are at rest, such as most normal cells.
What does chemotherapy damage?
Some chemo drugs can damage cells in the heart, kidneys, bladder, lungs, and nervous system. Sometimes, you can take medicines with the chemo to help protect your body’s normal cells. There are also treatments to help relieve side effects.
Which of the cells are most likely to be involved in chemotherapy side effects and why?
The fast-growing normal cells most likely to be affected by chemotherapy are blood cells forming in the bone marrow, and cells in the digestive tract, reproductive system, and hair follicles. Common side effects of chemotherapy include fatigue, nausea, diarrhea, mouth sores, hair loss, and anemia.
Can chemo permanently damage bone marrow?
Chemotherapy and radiation therapy can also damage bone marrow stem cells. This increases the risk of either acute leukemia or myelodysplasia.
Does chemo destroy the immune system?
Chemotherapy (often called chemo) is the most common cause of a weakened immune system in people getting cancer treatment. Chemotherapy can cause neutropenia (a decrease in the number of neutrophils, a type of white blood cell, in your blood).
How does chemo affect white blood cells?
Chemotherapy kills fast dividing cancer cells. It also ends up killing some fast dividing normal cells in the body, like those in the bone marrow that maintain the supply of white blood cells, or WBC, in your circulation. WBC counts fall temporarily with many different agents used as chemotherapy to treat cancer.
Why HeLa cells are special?
In 1952, HeLa cells became the first human cell line that could grow and divide endlessly in a laboratory, leading scientists to label these cells “immortal”. The immortality of HeLa cells contributed to their adoption across the world as the human cell line of choice for biomedical research.
What is the purpose of an oncogene?
Oncogene. An oncogene is a mutated gene that contributes to the development of a cancer. In their normal, unmutated state, onocgenes are called proto-oncogenes, and they play roles in the regulation of cell division. Some oncogenes work like putting your foot down on the accelerator of a car, pushing a cell to divide.
What happens after 3rd chemo treatment?
You may experience nausea (feeling like you might throw up) and vomiting (throwing up) after your last chemotherapy treatment. It should go away in 2 to 3 weeks. Your appetite may continue to be affected due to taste changes you may have experienced during your treatment.

- Hearing problems.
- Heart problems.
- Increased risk of blood cancers.
- Lung problems.
- Nerve damage.
- Reproductive changes.
Is chemo brain permanent?
Does chemobrain ever go away? For most patients, chemobrain improves within 9-12 months after completing chemotherapy, but many people still have symptoms at the six-month mark.
