How does radiation help cancer cells?
But cancer cells grow and divide faster than most normal cells. Radiation works by making small breaks in the DNA inside cells. These breaks keep cancer cells from growing and dividing and cause them to die.
How is radiation given?
Radiation therapy can be given in 3 ways: 1 External radiation (or external beam radiation): uses a machine that directs high-energy rays from outside the body into the tumor. It’s done during outpatient visits to a hospital or treatment center. It's usually given over many weeks and sometimes will be given twice a day for several weeks. A person receiving external radiation is not radioactive and does not have to follow special safety precautions at home. 2 Internal radiation: Internal radiation is also called brachytherapy. A radioactive source is put inside the body into or near the tumor. With some types of brachytherapy, radiation might be placed and left in the body to work. Sometimes it is placed in the body for a period of time and then removed. This is decided based on the type of cancer. Special safety precautions are needed for this type of radiation for a period of time. But it's important to know if the internal radiation is left in the body, after a while it eventually is no longer radioactive. 3 Systemic radiation: Radioactive drugs given by mouth or put into a vein are used to treat certain types of cancer. These drugs then travel throughout the body. You might have to follow special precautions at home for a period of time after these drugs are given.

How does cancer spread?
Cancer can spread from where it started to other body parts. Doctors often assume that a few cancer cells might already have spread even when they can’t be seen on imaging scans like CT scans or MRIs. In some cases, the area where the cancer most often spreads to may be treated with radiation to kill any cancer cells before they grow into tumors. For instance, people with certain kinds of lung cancer may get radiation to the head, even when there is no cancer known to be there, because their type of lung cancer often spreads to the brain. This is done to help prevent cancer from spreading to the head even before it can. Sometimes, radiation to prevent future cancer can be given at the same time that radiation is given to treat existing cancer, especially if the area the cancer might spread to is close to the tumor itself.

How does chemotherapy work?
Chemotherapy or drug therapy is used to kill cancer cells, while attempting to limit the damage to normal cells. Chemotherapy is useful in fighting cancer that has spread to other parts of the body and cannot be easily detected or treated with surgery or radiation therapy. Of the roughly 50 anticancer drugs, some can be used alone, or in combination with other anticancer drugs. Chemotherapy has been successful in treating acute leukemia, Hodgkin's and malignant lymphoma, small cell lung cancer, bladder and testicular cancer, and other forms of cancer. Chemotherapy can cure cancer in some cases, limit the spread of cancer, and help alleviate symptoms in some types of cancer. Chemotherapy can be used in combination with surgery and/or radiation, often with improved results.
What is cancer in the body?

What happens when a gene is damaged?
But when these genes are damaged, they can allow cancer to develop instead of preventing it. One of these genes, p53, normally prevents cells with abnormal DNA from surviving. When p53 is defective, these cells with abnormal DNA survive and can multiply, increasing the probability of developing cancer. Advertisement.
What is the ras gene?
For example, in some cancers, the ras gene (an oncogene) is mutated, and produces a protein that stimulates cells to divide prematurely. Other oncogenes, such as C-myc and C-erb B-2, when amplified, are implicated in small cell lung cancer and breast cancer, respectively.
How do chemo drugs work?
Chemotherapy drugs work in a few different ways. They can: 1 Kill both cancerous and healthy cells 2 Fight only cancer cells 3 Keep tumors from growing blood vessels, which help them thrive 4 Attack the cancer cells’ genes so the cells die and can’t grow into new tumors
