How does chemotherapy affect different parts of the body?
Cancer cells grow uncontrollably and often much quicker than other tissues and cells in the body, so these compounds damage them. But some specific parts of the body have a fast turnover of new cells and are also impacted by chemotherapy medications, leading to side effects in parts of the body that are unaffected by cancer.
Is chemotherapy harder on the body than radiation?
Both chemotherapy and radiation are important treatment approaches to improve survival in cancer patients, but they act on the body (and cancer) in different ways. You may wonder if being prescribed a treatment regimen that includes chemotherapy is harder on the body than if you’re given radiation treatments.

Which of the following types of cells are most likely to be damaged by exposure to radiation quizlet?
Which of the following types of cells are most likely to be damaged by exposure to radiation? Epithelial tissue and bone marrow. Institutions frequently have outbreaks of infection associated with poultry products contaminated by: Salmonella.
Which are the most critical adverse effects of chemotherapy and radiation therapy?
Anemia. Chemotherapy drugs and radiation can destroy all types of healthy blood cells and harm the body's production of new ones. Low levels of red blood cells (the cells that carry oxygen) can lead to anemia, which causes tiredness, paleness, shortness of breath, and a fast heartbeat.
Why are glucocorticoids often prescribed with chemotherapy and radiation because?
Glucocorticoids are frequently used as an adjuvant to mitigate adverse events during chemotherapy and radiation therapy. In humans, GCs have been shown to increase appetite; decrease vomiting, nausea, and weight loss; reduce fatigue; decrease ureteric obstruction; and alleviate bone pain associated with metastasis.
Why might it be beneficial to irradiate cancer cells?
Cancer cells multiply faster than normal cells in the body. Because radiation is most harmful to quickly growing cells, radiation therapy damages cancer cells more than normal cells. This prevents the cancer cells from growing and dividing, and leads to cell death.
What are the effects of radiation treatment?

How does chemo affect the body?
Chemotherapy can cause fatigue, loss of appetite, nausea, bowel issues such as constipation or diarrhoea, hair loss, mouth sores, skin and nail problems. You may have trouble concentrating or remembering things. There can also be nerve and muscle effects and hearing changes. You will be at increased risk of infections.
What do steroids do during chemo?
treat the cancer itself. reduce inflammation. reduce your body's immune response, for example after a bone marrow transplant. help reduce sickness when having chemotherapy.
Are glucocorticoids cytotoxic?
Much of what is known about glucocorticoids as a chemotherapeutic, and indeed many other cytotoxic agents, was learned from treatment of childhood leukemia. The predominant role of glucocorticoids in cancer is in the treatment of lymphoid malignancies.
What are examples of glucocorticoids?
Types of Glucocorticoids Among the most common ones are: Cortisone: a shot that can ease inflammation in your joints. Prednisone and dexamethasone: pills that treat allergies, arthritis, asthma, vision problems, and many other conditions. Triamcinolone: a cream that treats skin conditions.
How does radiation affect normal cells?
Radiation works by damaging the genes (DNA) in cells. Genes control how cells grow and divide. When radiation damages the genes of cancer cells, they can't grow and divide any more. Over time, the cells die.
What cells are most sensitive to radiation?
Lymphocytes (white blood cells) and cells which produce blood are constantly regenerating, and are, therefore, the most sensitive.
Which healthy cells are susceptible to radiation treatment?
Cancer cells are more vulnerable to radiation for two reasons: they divide more rapidly than normal cells. they do not repair this damage as effectively as normal cells.

What Is Chemotherapy?
One of the oldest treatments for cancer is chemotherapy, in which drugs are given through an intravenous (IV) injection or orally. Chemotherapy can have effects system-wide, which means it impacts your whole body. 1
What Is Radiation?
Radiation is a high-energy invisible light wave. Because it has a lot of energy, it can be directed at cancer cells to damage their genetic material, ultimately killing them. 2
Benefits and Risks of Chemotherapy
Chemotherapy is an essential treatment option for many cancers. The drugs used in chemotherapy are often given so that they can reach and kill cancer cells system-wide, outside of the primary tumor your doctor may have discovered.
Which Is Harder on the Body: Chemo or Radiation?
It is difficult to say what cancer therapy will be more difficult for your body to handle. Different types and dosages of both chemotherapy and radiation will have different effects.
Can Chemo and Radiation Be Used Together to Treat Cancer?
Some cancers can be treated with just radiation. These are most often cancers caught early—before they've grown large or started to spread.
Managing the Side Effects of Cancer Treatment
Many of the side effects of cancer treatment can be effectively managed or lessened. Palliative care (treatment to reduce the burden of symptoms) is an important part of any cancer treatment plan.
How does chemotherapy work?
Chemotherapy usually involves a combination of drugs in order to: 1. reduce the adverse effects. 2. guarantee that all cancer cells are destroyed. 3. be effective in more phases of the cell cycle. 4. totally block the mitotic stage. 1 ,3. -reduce the adverse effects. - be effective in more phases of the cell cycle.
What are the adverse effects of radiation and chemotherapy?
