What is Bolus used for?

In radiation therapy bolus is often used when treating uneven areas of a patient, such as at the nose or ears, to make up for missing tissue, or to provide build-up of dose to the skin surface. The bolus should be tissue equivalent, sufficiently flexible to conform to the patient surface, durable and cost effective.

What is Bolus made of?

In digestion, a bolus (from Latin bolus, “ball”) is a ball-like mixture of food and saliva that forms in the mouth during the process of chewing (which is largely an adaptation for plant-eating mammals).

Where is Bolus found in the body?

Bolus, food that has been chewed and mixed in the mouth with saliva. Chewing helps to reduce food particles to a size readily swallowed; saliva adds digestive enzymes, water, and mucus that help chemically to reduce food particles, hydrate them for taste, and lubricate them for easy swallowing.

Is radiation worse than chemo?

The radiation beams change the DNA makeup of the tumor, causing it to shrink or die. This type of cancer treatment has fewer side effects than chemotherapy since it only targets one area of the body.

What happens to dead cancer cells after radiation?

When the damaged cells die, they are broken down and removed by the body. Radiation therapy does not kill cancer cells right away. It takes days or weeks of treatment before DNA is damaged enough for cancer cells to die. Then, cancer cells keep dying for weeks or months after radiation therapy ends.

What bolus means?

Definition of ‘bolus’ 1. a small round soft mass, esp of chewed food. 2. an intravenous injection of a single dose of a drug over a short period.

How much is 1 Gy of radiation?

Absorbed dose is measured in joules/kilogram, and a quantity of 1 joule/kilogram has the special unit of gray (Gy) in the International System of quantities and units. (In terms of the older system of radiation quantities and units previously used, 1 Gy equals 100 rad, or 1mGy equals 0.1 rad.)

What is used to kill cancer cells in radiotherapy?

Radiation therapy uses high-energy radiation to shrink tumors and kill cancer cells (1). X-rays, gamma rays, and charged particles are types of radiation used for cancer treatment.
