Clinical Trials Method of Treatment for Cancer

Cancer Treatment - Research studies of the latest drugs and therapies against many types of cancer are continuously being conducted. This type of research requires human volunteers to test the safety and effectiveness of new therapies. Volunteers must meet the criteria of each study to participate.

Biologic or Targeted Therapy Method of Treatment for Cancer

Cancer Treatment - Biologic therapy is a term for drugs that target characteristics of cancerous tumors. Some types of targeted therapies work by blocking the biological processes of tumors that allow tumors to thrive and grow. Other types of therapies cut off the blood supply to the tumor, causing it to basically starve and die because of a lack of blood.

Targeted therapy is used in select types of cancer and is not available for everyone. It is given in conjunction with other cancer treatments.

Radiation Therapy Method of Treatment for Cancer

Cancer Treatment - Radiation therapy uses certain types of energy to shrink tumors or eliminate cancer cells. It works by damaging a cancer cell's DNA, making it unable to multiply. Cancer cells are highly sensitive to radiation and typically die when treated. Nearby healthy cells can be damaged as well, but are resilient and are able to fully recover.
Radiation therapy may be given alone, along with chemotherapy, and/or with surgery. The decision to combine radiation therapy with other types of treatment depends on the stage of cancer and other factors.

Chemotherapy Method of Treatment for Cancer

Cancer Treatment - Chemotherapy is a type of cancer treatment that uses of drugs to eliminate cancer cells. Unlike surgery, chemotherapy affects the entire body, not just a specific part. It works by targeting rapidly multiplying cancer cells. Unfortunately, other types of cells in our bodies also multiply at high rates, like hair follicle cells and the cells that line our stomachs. This is why chemo can cause side effects like hair loss and an upset stomach.
Chemotherapy is most commonly given by pill or intravenously (IV), but can be given in other ways. A single type of chemotherapy, or a combination of drugs, may be prescribed for a specific length of time. Like surgery, chemotherapy can be prescribed alone, in conjunction with radiation therapy or biologic therapy.

Surgery Method of Treatment for Cancer

Cancer Treatment - Surgery can be used to prevent, treat, stage (determine how advanced the cancer is), and diagnose cancer. In relation to cancer treatment, surgery is done to remove tumors or as much of the cancerous tissue as possible. It is often performed in conjunction with chemotherapy or radiation therapy.

For those whose cancer is not treatable, palliative surgery may be an option to relieve pain that may be caused by the cancer. Palliative surgery is not intended to treat or cure the cancer, or even to prolong life, but more to lessen discomfort.

Cancer Prevention

Cancer Treatment - Most people don't realize that cancer is preventable in many cases. Learning what causes cancer and what the risk factors are is the first step in cancer prevention. Many cancer risk factors can be avoided, thus reducing the likelihood of developing cancer. Of course, some cancer risks like genetics cannot be avoided.
Smoking is the most significant cancer risk factor that we can reduce. It is responsible for not only lung cancer, but many other types of cancer. One of the best ways to prevent cancer is to quit smoking or never start. As soon as you quit, and it's never too late, your body reaps the benefits of being tobacco-free.

Treatment of Cancer

Cancer Treatment - There are four standard methods of treatment for cancer: surgery, chemotherapy, radiation therapy, and immunotherapy/biologic therapy. When initially diagnosed with cancer, a cancer specialist (called an oncologist) will provide the patient with cancer treatment options. He or she will recommend the best treatment plan based on the type of cancer, how far it has spread, and other important factors like age and general health.
Ultimately, it is the patient who makes the treatment decisions based on doctor's recommendations, possible second opinions, and other information gathered from qualified professionals.

How Does Cancer Spread to Other Parts of the Body?

Cancer Treatment - The cells within malignant tumors have the ability to invade neighboring tissues and organs, thus spreading the disease. It is also possible for cancerous cells to break free from the tumor site and enter the bloodstream, spreading the disease to other organs. This process of spreading is called metastasis.
When cancer has metastasized and has affected other areas of the body, the disease is still referred to the organ of origination. For example, if cervical cancer spreads to the lungs, it is still called cervical cancer, not lung cancer.
Although most cancers develop and spread this way - via an organ - blood cancer like leukemia do not. They affect the blood and the organs that form blood and then invade nearby tissues.

How Does Cancer Develop?

Cancer Treatment - The organs in our body are made up of cells. Cells divide and multiply as the body needs them. When these cells continue multiplying when the body doesn't need them, the result is a mass or growth, also called a tumor.
These growths are considered either benign or malignant. Benign is considered non-cancerous and malignant is cancerous. Benign tumors rarely are life threatening and do not spread to other parts of the body. They can often be removed.

Malignant tumors, however, often invade nearby tissue and organs, spreading the disease.
