Areas of Treatment
BrainBrain 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
Breast 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.
