Areas of Treatment



Brain tumors cause damage because, as they grow, they can interfere with surrounding cells that serve vital roles in our everyday life. There are two types of brain tumors:

Primary - a tumor that starts in the brain. Primary brain tumors can be benign (not cancerous) or malignant (cancerous). Primary tumors in the brain or spinal cord rarely spread to distant organs.

Metastatic - a tumor caused by cancer elsewhere in the body that spreads to the brain. Metastatic brain tumors are always cancerous.


Radiation therapy is the use of high-energy rays to kills tumor cells, thereby stopping them from growing and multiplying. Radiation therapy may be used for people who cannot undergo surgery.


In other cases, it is used after surgery to kill any tumor calls that may remain. Radiation therapy can be combined with chemotherapy in some cases. Radiation therapy is a local therapy, which means that it affects only cells involved within the tumor area. Treatment of the Brain tumor is usually delivered in the form of 3-d therapy, IMRT or in some selective cases Stereotactic radiosurgery which is a newer "knifeless" technique that destroys a brain tumor without opening the skull. A CT or MRI scan is used to pinpoint the exact location of the tumor in the brain. High-energy radiation beams are trained on the tumor from different angles. The radiation destroys the tumor. There are various types of stereotactic radiosurgery



Surgery is often necessary with a diagnosis of breast cancer. There are different options regarding surgery, which is usually followed by radiation and chemotherapy. Your doctor can review the different types of surgery and discuss radiation options after diagnosis.



Cervical cancer can be treated with external and internal radiation. A team of doctors will help you decide which treatment is best for you and if you should combines treatments for the best possible outcome.

Radiation therapy is frequently used in patients with colon cancer, and may be used either before or after surgery. It is used prior to surgery in order to shrink the tumor and make it easier to remove. After surgery the radiation may kill any remaining cancer cells that could not be removed during surgery. Radiation therapy may also be used to relieve the symptoms that are caused by the cancer such as pain or pressure.



If you develop prostate cancer, you should discuss treatment options with your radiation oncologist. There are many different types of procedures offered when dealing with prostate cancer, with combinations of procedures sometimes being the best solution.

Lung cancer treatment depends on several factors, including the type and size of the cancer, its location and your overall health. Surgery, radiation therapy and chemotherapy are the primary tools for treating lung cancer and may be used alone or in combination. A team of doctors will help you decide which treatment is best for you.


Radiation therapy, usually combined with chemotherapy, is often used to treat patients after surgery to prevent recurrence of pancreatic cancer. Radiation therapy is also sometimes used for patients whose cancer is too advanced to be removed surgically. The most common type of radiation therapy used in treating pancreatic cancer is IMRT/IGRT radiation therapy. Our Radiation Oncologist are not only concerned about treating the cancer but decreasing the toxicity, and or damage to healthy tissue so you can maintain your quality of life throughout your course of treatment.


Radiation therapy can be used in combination with other treatments, such as chemotherapy, or surgery, or it can be used alone in the treatment of the disease. Radiation therapy has been used successfully in the treatment of lymphomas for many years. Lymph cells are incredibly sensitive to radiation, which is why this treatment is so effective. The external-beam radiation therapy will target and destroy cancerous cells but will limit the dose to healthy tissue.
