For some people, radiation therapy may be the only treatment they need. But, most often, you will undergo radiation therapy along with other cancer treatments, such as surgery, chemotherapy, and immunotherapy. Your oncologist will decide on the amount and type of radiation based on the type of cancer. Radiation therapy normally happen over the course of several sessions that are spread over a few weeks.
Following the CT scan your oncologist will put a permanent small ink mark on your skin to ensure that the radiation is targeted accurately. He/she will then begin your radiation therapy.
There are two different ways of giving radiation therapy:
External Beam Radiation Therapy: In this type of radiation therapy radiation comes from an external machine and gets directed towards your cancer. It is helpful in treating a specific part of your body that has cancer.
Internal Radiation Therapy: In this type of radiation therapy the radiation source either solid or liquid is placed inside your body. When a solid source of radiation is used in internal radiation therapy it is called brachytherapy. It is also a local treatment and treats only a specific part of your body.
How you are given radiotherapy will depend on the type of cancer you have and where it is in the body.
Cancer and radiation therapy can cause extreme physical and emotional distress. Hence it is important to eat well and practice yoga or meditation to cope with the side effects of cancer treatment.Learn Less
