What is conformal radiation?

Conformal radiation therapy: A procedure that uses computers to create a 3-dimensional picture of the tumor in order to target the tumor as accurately as possible and give it the highest possible dose of radiation while sparing normal tissue as much as possible.

What does conformal radiotherapy mean?

3D conformal radiation therapy is a cancer treatment that shapes the radiation beams to match the shape of the tumor. In the past, radiation beams only matched the height and width of the tumor — exposing healthy tissue to radiation.

Is fasting required for radiation therapy?

Fasting may also protect patients against the harmful side effects of chemotherapy or radiation therapy. Fasting for up to five days, followed by a normal diet prior to treatment may reduce side effects from treatment, without causing chronic weight loss or interfering with the therapeutic effect of treatment (14).

What is the difference between 3dcrt and IMRT?

Three-dimensional conformal radiotherapy (3D-CRT) and intensity-modulated radiotherapy (IMRT) are 2 recently developed radiotherapy techniques. IMRT is believed to be more effective than 3D-CRT in target coverage, dose homogeneity, and reducing toxicity to normal organs.

Which member of the radiation oncology team determines the treatment plan?

Final decisions regarding the treatment plan are made by the radiation oncologist. Many dosimetrists start as radiation therapists and with intensive training, become medical dosimetrists. Others are graduates of one- to two-year dosimetry programs. The Medical Dosimetrist Certification Board certifies dosimetrists.

How long do you have to fast for autophagy?

Depending on the individual's metabolism, significant autophagy may take two to four days of fasting in humans. Autophagy is believed to begin when glucose and insulin levels drop considerably. Animal studies have shown evidence of autophagy after 24 hours of fasting, which starts peaking at around 48 hours of fasting.

Is it good to eat before radiation treatment?

  • Intermittent fasting is especially beneficial for those undergoing abdominal or pelvic radiation. Studies suggests that there may be less intestinal side effects in pancreatic cancer patients who fast before treatments. So, don’t worry too much if you are just not up to eating on occasion.

What foods should you not eat during radiation therapy?

  • Consumption of raw or undercooked foods should be avoided to limit the risk of food poisoning. For example, if you are currently receiving radiation therapy or recently stopped, your doctor may recommend not eating cold deli lunch meat, unpasteurized milk, undercooked eggs, unwashed fruits and vegetables, undercooked/raw shellfish, sushi and more.

What foods to eat when you have radiation in your mouth?

  • Choosing foods that are soft and easy to chew may make it easier to get the nutrients you need. Consider moistening foods with sauces and broth, eating room-temperature food and drinking with a straw. Sucking on ice chips and using a salt water rinse also may help soothe your mouth.

Do you need to take supplements during radiation treatment?

  • If you are struggling to eat enough food, you may need to take a vitamin and mineral supplement. Always check with your health care provider before starting any new supplements. Some supplements may interact with your medicines or treatments. Changes in eating are common during periods of radiotherapy.
