Your team at VCI brings many of the most advanced treatments for cancer right here to Central Virginia. Your individual choice of cancer treatment depends on several factors, including the specific characteristics of your cancer, your overall condition and whether the goal of treatment is to cure your cancer, keep your cancer from spreading or relieve the symptoms caused by cancer. Based on these factors, you may receive one or more of the following:
• Radiation therapy
• Hormonal therapy
• Targeted therapy
• Biological therapy
Increasingly, it is common to use several treatment modalities together (concurrently) or in sequence with the goal of preventing recurrence. This is referred to as multimodality treatment of the cancer.
Surgery is used to diagnose cancer, to determine its stage and to treat it. One common type of surgery that may be used to help with diagnosing cancer is a biopsy. A biopsy involves taking a tissue sample from the suspected cancer for examination by a specialist in a laboratory. Biopsies are typically performed in one of our affiliated hospitals, outpatient surgery centers or VCI offices. A positive biopsy indicates the presence of cancer; a negative biopsy may indicate that no cancer is present in the sample.
When surgery is used for treatment, the cancer and some tissue adjacent to the cancer are typically removed. In addition to providing local removal of the cancer, information gained during surgery is useful in predicting the likelihood of cancer recurrence and whether other treatment modalities will be necessary.

Chemotherapy is any treatment involving the use of drugs to kill cancer cells. Cancer chemotherapy may consist of single drugs or combinations of drugs and can be administered through a vein, injected into a body cavity or delivered orally in the form of a pill. Chemotherapy is different from surgery or radiation therapy in that the cancer-fighting drugs circulate in the blood to parts of the body where the cancer may have spread and can kill or eliminate cancer cells at sites great distances from the original cancer. As a result, chemotherapy is considered a systemic treatment.
More than half of all people diagnosed with cancer receive chemotherapy. For millions of people who have cancers that respond well to chemotherapy, this approach helps treat their cancer effectively, enabling them to enjoy full, productive lives. Furthermore, many side effects once associated with chemotherapy are now easily prevented or controlled, allowing many people to work, travel and participate in many of their other normal activities while receiving chemotherapy.
Radiation therapy, or radiotherapy, uses high-energy rays to damage or kill cancer cells by preventing them from growing and dividing. Similar to surgery, radiation therapy is a local treatment used to eliminate or eradicate visible tumors. Radiation therapy is not typically useful in eradicating cancer cells that have already spread to other parts of the body. Radiation therapy may be externally or internally delivered.
External radiation delivers high-energy rays directly to the tumor site from a machine outside the body. Internal radiation, or brachytherapy, involves the implantation of a small amount of radioactive material in or near the cancer. Radiation may be used to cure or control cancer, or to ease some of the symptoms caused by cancer. Sometimes radiation is used with other types of cancer treatment, such as chemotherapy and surgery, and sometimes it is used alone.

Hormones are naturally occurring substances in the body that stimulate the growth of hormone-sensitive tissues, such as the breast or prostate gland. When cancer arises in breast or prostate tissue, its growth and spread may be caused by the body’s own hormones. Hormonal therapy fights cancer with drugs that block hormone production or change the way hormones work, and/or by removing organs that secrete hormones, such as the ovaries or testicles, are ways of fighting cancer. Hormonal therapy, similar to chemotherapy, is a systemic treatment in that it may affect cancer cells throughout the body. Learn more about hormonal therapy.
A targeted therapy is one that is designed to treat only the cancer cells and to minimize damage to normal, healthy cells. Cancer treatments that “target” specific types of cancer cells may offer the advantage of reduced treatment-related side effects and improved outcomes. Learn more about targeted therapy.
Biological therapy is referred to by many terms, including immunologic therapy, immunotherapy or biotherapy. Biological therapy is a type of treatment that uses the body’s immune system to facilitate the killing of cancer cells. Types of biological therapy include interferon, interleukin, monoclonal antibodies, colony-stimulating factors (cytokines) and vaccines.
Personalized cancer care
There is no longer a “one-size-fits-all” approach to cancer treatment. Even among patients with the same type of cancer, the behavior of the cancer and its response to treatment can vary widely. By exploring the reasons for this variation, researchers have begun to pave the way for more personalized cancer treatment. It is becoming increasingly clear that specific characteristics of cancer cells and cancer patients can have a profound impact on prognosis and treatment outcome. Although factoring these characteristics into treatment decisions makes cancer care more complex, it also offers the promise of improved outcomes.
The idea of matching a particular treatment to a particular patient is not a new one. It has long been recognized, for example, that hormonal therapy for breast cancer is most likely to be effective when the breast cancer contains receptors for estrogen and/or progesterone. Testing for these receptors is part of the standard clinical workup of breast cancer. What is new, however, is the pace at which researchers are identifying new tumor markers, new tests and new, more targeted drugs that individualize cancer treatment. Tests now exist that can assess the likelihood of cancer recurrence, the likelihood of response to particular drugs and the presence of specific cancer targets that can be attacked by new anticancer drugs that directly target individual cancer cells.
