what is strong treatment chemo or radiation therapy

Chemotherapy

uses very strong drugs, and radiation therapy uses high energy waves to treat the disease by killing cancer cells. Radiation therapy is targeted to localized cancer i.e., specific organs in the body where cancerous tissue is present. Chemotherapy can be used when cancer cells have spread to other parts of the body.

Full Answer

What type of radiation is used to treat cancer?

Radiation therapy Radiation therapy is a type of cancer treatment that uses beams of intense energy to kill cancer cells. Radiation therapy most often uses X-rays, but protons or other types of energy also can be used. The term "radiation therapy" most often refers to external beam radiation therapy.

What is the difference between chemo and radiation therapy?

Chemotherapy vs. Radiation Therapy. There are 4 major types of treatment for cancer — radiation, chemotherapy (often called chemo), surgery and biologic therapies. Chemotherapy uses very strong drugs, and radiation therapy uses high energy waves to treat the disease by killing cancer cells.

What is chemotherapy for cancer treatment?

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 The goal of chemotherapy is to kill the cancer cells, shrink the tumor, or destroy the tumor.

What are the treatment options for cancer?

However, there are many treatment options that work to fight off cancer cells and prevent them from spreading. Chemotherapy and radiation are among the most effective treatments for most types of cancer. Although they have the same goals, there are key differences between the two types of therapy.

Is radiotherapy as good as 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.

What treatment comes first chemo or radiation?

Radiation generally starts after chemotherapy is done.

Is radiation the most effective treatment for cancer?

At high doses, radiation therapy kills cancer cells or slows their growth by damaging their DNA. Cancer cells whose DNA is damaged beyond repair stop dividing or die. When the damaged cells die, they are broken down and removed by the body. Radiation therapy does not kill cancer cells right away.

At what stage of cancer is radiotherapy used?

Radiotherapy may be used in the early stages of cancer or after it has started to spread. It can be used to: try to cure the cancer completely (curative radiotherapy) make other treatments more effective – for example, it can be combined with chemotherapy or used before surgery (neo-adjuvant radiotherapy)

Which is worse chemo 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.

What is the success rate of radiation therapy?

“When patients are treated with modern external-beam radiation therapy, the overall cure rate was 93.3% with a metastasis-free survival rate at 5 years of 96.9%.

Do tumors grow back after radiation?

Normal cells close to the cancer can also become damaged by radiation, but most recover and go back to working normally. If radiotherapy doesn't kill all of the cancer cells, they will regrow at some point in the future.

What percentage of cancer is treated with radiation?

Radiation therapy remains an important component of cancer treatment with approximately 50% of all cancer patients receiving radiation therapy during their course of illness; it contributes towards 40% of curative treatment for cancer.

Do tumors continue to shrink after radiation?

At the same time, if a cell doesn't divide, it also cannot grow and spread. For tumors that divide slowly, the mass may shrink over a long, extended period after radiation stops. The median time for a prostate cancer to shrink is about 18 months (some quicker, some slower).

Can cancer spread during radiotherapy?

There are preclinical and clinical reports showing that focal radiotherapy can both increase the development of distant metastasis, as well as that it can induce the regression of established metastases through the abscopal effect.

Can cancer spread during chemo and radiation?

It is possible that cancer can spread while undergoing cancer treatments like chemotherapy. Doctors use regular scans and testing to determine how your chemotherapy treatment is working. If cancer continues to spread, they may recommend changes to the treatment plan.

Comparison chart. Chemotherapy is the treatment of cancer with one or more cytotoxic anti-neoplastic drugs ("chemotherapeutic agents") as part of a standardized regimen. Radiation therapy is the medical use of ionizing radiation, generally as part of cancer treatment to control or kill malignant cells.

How effective is radiation therapy?

Chemotherapy and radiation are normally effective in the early stages of cancer. In cases of chroniccancer, chemotherapy may not cure but can help control the disease for months or years. Sometimes immunity is developed to certain drugs and in case of a relapse; doctors might take a different approach to the treatment and switch drugs. Sometimes radiation therapy might be the only way to treat cancer and can help with remission. In cases where there is a relapse, radiation therapy may not cure but can control symptoms. Depending on the case, cancer can go into remission for 5, 10, or even 20 years. There is no way of saying how long a cancer will stay in remission. Once in remission, doctor visits are required at scheduled intervals to monitor the progress. The longer the remission period, better are the chances that cancer will not relapse.

What are the different types of cancer treatments?

How is chemo given?

Chemotherapy is given according to the type and stage of cancer. When used to treat the entire body, the cancer has usually spread to more than one part of the body. Doctors use chemotherapy to destroy cancer cells, control or slow the spread of cancer cells and reduce symptoms like pain associated with tumors. Chemotherapy is administered in various ways: 1 Injection: Given as a shot 2 Intra-arterial: Often used in case of a tumor.

How do doctors treat cancer?

Your medical team will deliver your radiation therapy through one or more of these methods: 1 External radiation: A machine outside the body shoots invisible high-energy beams into the tumor. 2 Internal radiation: This is sometimes called “brachytherapy.” Doctors place a radioactive object inside your body close to the tumor. They might leave it in to do its work or they may take it out soon afterward. 3 Systemic radiation: Though less common, your doctor might suggest using radiation as a systemic treatment that works throughout the body.
