Advantages Chemotherapy may shrink your cancer or slow down its growth, which may help you live longer and help with your symptoms. For a small number of people with borderline resectable cancer, chemotherapy may shrink the cancer enough to make surgery to remove the cancer possible.
What are the benefits of chemotherapy?
The main benefit of chemotherapy is its potential to destroy cancer cells. It remains one of the most potent tools we have to fight cancer. The potential benefit to each patient depends on treatment goals, which depend on the type of cancer, how advanced it is and what the patient hopes to get out of treatment.
What is the difference between chemotherapy and radiation therapy?
Chemotherapy is delivered through an infusion into a vein or medication port, or it can be taken orally. With radiation therapy, beams of radiation are focused on a specific area in your body. The goal of both types of treatment is to destroy the cancer cells while limiting the effects on the rest of your body.
When to use Chemo or radiation for cancer?
When and whether to use chemo or radiation depends on the cancer, the individual’s treatment goals, and other factors. Sometimes, chemotherapy comes first, but this is not always the case. In some cases, a person only has radiation or radiation and chemo at the same time.
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.
What is better for cancer chemotherapy or radiation?
The radiation beams change the DNA makeup of the tumor, causing it to shrink or die. This type of cancer treatment has fewer side effects than chemotherapy since it only targets one area of the body.
Why would you use chemo instead of radiation?
Summary. Chemotherapy and radiation therapy are each used to treat cancer. The decision about which one is used depends on the type, location, and spread of the cancer. Chemotherapy is a systemic treatment, while radiation therapy is often a localized treatment but may be systemic.
What is better chemotherapy or surgery?

What is the main difference between chemotherapy and radiation?
Chemotherapy and radiation therapy are both treatments for cancer – the uncontrolled growth and spread of cells to surrounding tissues. Chemotherapy, or “chemo,” uses special drugs to shrink or kill cancer cells. Radiation therapy, or “radiation,” kills these cells with high-energy beams such as X-rays or protons.
What's the difference between radiotherapy and chemotherapy?
Chemotherapy uses anti-cancer (cytotoxic) drugs to destroy cancer cells. Radiotherapy uses high-energy rays to destroy cancer cells. The chemotherapy drugs can make cancer cells more sensitive to radiotherapy. Combining both treatments is often more effective than having either treatment on its own.
Why is chemotherapy done over surgery?
The aim of chemotherapy after surgery or radiotherapy is to lower the risk of the cancer coming back in the future. This is called adjuvant treatment. The chemotherapy circulates throughout your body and kills off any cancer cells that have broken away from the main tumour before your operation.
Why is chemotherapy recommended?
Chemotherapy can be used to shrink a tumor so that other treatments, such as radiation and surgery, are possible. Doctors call this neoadjuvant therapy. To ease signs and symptoms. Chemotherapy may help relieve signs and symptoms of cancer by killing some of the cancer cells.

Do the benefits of chemotherapy outweigh the risks?
Although chemotherapy slightly reduces the risk of their cancer coming back, doctors consider the side effects to outweigh this potential advantage. Some experts call it a “low risk of recurrence” if the cancer comes back in less than 5 out of 100 women with that risk within 10 years.
What are the side effects of radiation?
The side effects of radiation include redness on the skin in the area that the radiation passes through, fatigue that does not get better with rest, and sometimes loss of appetite and nausea. Most skin reactions and other side effects improve when treatment ends.
What is the treatment for colon cancer?

Can you have surgery to remove a tumor?
In many cases of early stage non-small cell lung cancers and carcinoid tumors, surgery to remove the tumor and surrounding lung tissue is the first choice. This is possible if the cancer is localized, has not spread and the patient’s physical health allows what the American Cancer Society calls “curative or primary surgery.” In some cases, surgery may be combined with chemotherapy or radiation therapy, which can be given before the operation to shrink the tumor or after surgery to kill any cancer cells left behind.
Why is chemotherapy used for cancer?
Otherwise cancer that has spread to various parts of the body or developed in a unreachable location, chemotherapy is recommended for destroying the cancer and controlling it .
How does chemo work?
Combined, chemotherapy and surgery work effectively together. Used before surgery, chemotherapy can reduce the size of the sarcoma, making surgery less invasive for a patient. In cases where cancer has spread, chemotherapy eliminates microscopic areas of metastasis.
Is sarcoma treated with chemotherapy or surgery?
Chemotherapy vs Surgery. Many sarcoma patients are not diagnosed until their disease develops noticeable symptoms, but by then, sarcoma has reached an advanced stage. Treatment then becomes more complex, involving multiple methods to destroy tumors and stop further spread of the disease.
Why is chemo used for cancer?
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.
Why is chemo important?
So chemotherapy is an important treatment option to help kill cancer cells that may have escaped the primary tumor and spread to other parts of the body but are too small to see ; these are called micrometastases. 3
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
Why do we give radiation before surgery?
For example, chemo or radiation may be given before surgery to shrink a tumor to make it easier to remove. Or they may be given after surgery to ensure all cancer cells are removed from the body.
What is the goal of chemo?
The goal of chemotherapy is to kill the cancer cells, shrink the tumor, or destroy the tumor. Destroying the tumor can eliminate cancer, while shrinking it can relieve some symptoms if the tumor is causing pain or interfering with other tissues.
What can help with tumors?
Chemotherapy can also help treat any tumor pieces or cells left over after other treatment approaches, like surgery or radiation therapy.
Why are combination treatments used?
Combination treatments are used for many reasons. Treatments may be more effective when they’re combined. For example, chemotherapy may make radiation treatments more effective.

The potential benefit to each patient depends on treatment goals, which depend on the type of cancer, how advanced it is and what the patient hopes to get out of treatment.
Why do people get chemotherapy after surgery?
The same patient may benefit from chemotherapy after surgery to try to destroy remaining cancer cells. Chemotherapy may also be used to relieve symptoms caused by advanced cancer, which improves a patient’s quality of life. Some of these patients may be able to take occasional breaks from treatment.
How is chemotherapy used in cancer treatment today?
How chemotherapy is used in treatment depends on the type and stage of the cancer and how aggressive it is. Some cancers, such as an indolent lymphoma or prostate cancer, may not need immediate treatment, but chemotherapy may eventually be recommended if the cancer progresses. Other cancers require immediate treatment.
What does a medical oncologist do?
A medical oncologist provides a balanced, in-depth look at what you need to know. If you're like many cancer patients, you immediately envision an unpleasant experience at the thought of chemotherapy: weeks of intense nausea and vomiting, diarrhea, fatigue and transient hair loss. These preconceived ideas about chemotherapy aren’t entirely accurate.
What is evidence-informed supportive care?
Evidence-informed supportive care therapies are designed to prevent and manage side effects a patient may experience during conventional cancer treatment. Early access to these types of therapies may help prevent, manage or reduce the severity of common side effects, which may also prevent treatment disruptions and improve patients’ quality of life during and after treatment.

Having access to a supportive care team to create a plan, answer questions and be on call to provide help as needed may significantly improve your treatment experience.
Why are the side effects of chemotherapy and radiation similar?
Because chemotherapy and radiation damage both healthy cells and cancerous cells, the side effects are similar.
What is the purpose of chemotherapy?
In chemotherapy, doctors administer chemotherapeutic agents, a large group of drugs that can slow or stop the growth of cells. Most of them target fast-growing cells that divide and proliferate. However, they do not distinguish between healthy cells and cancer cells.

Can radiation and chemotherapy be used together?
Additionally, chemotherapy and radiation can complement each other, and doctors may administer them together.
Chemotherapy
Chemotherapy has two main distinguishing factors. First, it uses specialized drugs that are designed to target and kill cells that divide rapidly (like cancer cells). Second, these drugs work throughout the entire body, not just one specific part, so they can prevent cancer cells from spreading to other parts of the body.
Radiation Therapy
Radiation therapy works much differently. While chemotherapy delivers drugs to the entire body, radiation aims to only target the specific area of the body where there are cancerous cells, and aims to reduce the number of healthy cells that are affected during treatment.
How Radiation Therapy and Chemotherapy are Used to Treat Cancer
No body and no cancer is created equal. And no approach to cancer treatment should be created equal, too. While chemotherapy and radiation therapy are both designed to treat the body and to fight cancer, each does so in different ways.
