Radiation Treatment for Head and Neck Cancer

Radiation therapy for head and neck cancers uses high-energy doses of radiation to target and kill cancer cells. It does this by destroying the DNA of the cells so they cannot grow or multiply. It typically takes several treatments to damage cancer cells enough for them to die, after which the body simply gets rid of them.

When used with precision, this head and neck cancer treatment can effectively destroy cancerous cells while preserving surrounding healthy tissue. Cancer cells are more sensitive to radiation than normal, healthy cells, so radiation treatments are able to effectively shrink tumors and in most cases eliminate them completely.

At Oncology Las Vegas, we strive to be at the forefront of advanced radiation technology so we can deliver radiation treatments with accuracy. Our state-of-the-art equipment allows us to map out the size and location of the tumor so that we can then deliver high doses of radiation to the tumor with precision, sparing surrounding healthy tissue. This not only makes head and neck cancer treatment more effective, but it can also help to reduce side effects from receiving radiation.

For head and neck cancers, which can include throat cancer, mouth cancer, laryngeal cancer, oropharynx (tongue and tonsil), and cancer in the nasal cavity, nasopharynx and sinuses, precision is particularly important. These areas of the head and neck contain many critical and delicate tissues that are important to preserve. If a patient has a tumor the size of a grape, we do not treat an area the size of a grapefruit.

After being diagnosed with head and neck cancer, the first step is to pinpoint the exact size and location of the tumor. We use advanced imaging technology to create a detailed map of the tumor and surrounding areas so we can deliver radiation treatments accurately. Other imaging or procedures such as a scope of the head and neck may aid in targeting the tumor. Your radiation oncologist will also determine how many treatments are needed and if other treatments in addition to the radiation (such as chemotherapy or surgery) may also be indicated. Typically, radiation therapy for head and neck cancers is given five days a week for several weeks, but some cases are treated in as few as five treatments.

Treatment sessions usually last between 15-30 minutes while the patient lies still on a treatment table. This process is painless and non-invasive, and we strive to make our patients completely comfortable. Some patients may feel so relaxed they end up taking a quick nap.

Side effects from head and neck cancer treatment can include hair loss, loss of appetite, skin irritation, dry mouth, soreness of the mouth or throat, fatigue, and others. Patients may not experience side effects until after a couple of weeks of receiving treatment. The majority of side effects are temporary and cease after treatment is completed. Your radiation oncologist can answer any questions you may have about possible side effects and provide tips on how to manage them.

Receiving a diagnosis of head and neck cancer can be overwhelming. It is crucial to have a compassionate team to support you. Our staff is caring and dedicated to creating the best possible outcome for patients with head and neck cancers. We are there for you every step of the way.
