If severe, this can affect swallowing, and the patient may need painkillers and nutritional support/food supplements. The esophagus can also become sore if it is treated directly, or if, as commonly occurs, it receives a dose of collateral radiation during treatment of lung cancer.
A tumor may impair a person's ability to swallow and eat, and throat cancer may affect the digestive system. The difficulty in swallowing can cause a person to choke on their food in the early stages of digestion and interfere with the food's smooth travel down into the esophagus and beyond.

Advances in radiation therapy have decreased the incidence of ORN, estimated at around 2%. [6] Certain risk factors including the size and location of tumor, [7] [8] history of smoking [2] or diabetes, [7] and presence of dental disease [3] [9] can affect the chances of developing ORN. Osteoradionecrosis is difficult to prevent and treat.
Koyfman believed that stereotactic body radiation therapy, “high dose radiation to very small areas,” could benefit Agler. “(It is) much more effective at eradicating the tumor in a shorter ...
A radiation dose of 52 Gy is sufficient to cause severe salivary dysfunction. Radiotherapy for oral cancers usually involves up to 70 Gy of radiation, often given along with chemotherapy which may also have a damaging effect on saliva production. [8] This side effect is a result of radiation damage of the parasympathetic nerves.
Among patients undergoing head and neck radiotherapy, pain and decreased oral function may persist long after the conclusion of therapy. Fractionated radiation dosage increases the risk of mucositis to > 70% of patients in most trials. Oral mucositis is particularly profound and prolonged among HSCT recipients who receive total-body irradiation ...
In medicine, proton therapy, or proton radiotherapy, is a type of particle therapy that uses a beam of protons to irradiate diseased tissue, most often to treat cancer.The chief advantage of proton therapy over other types of external beam radiotherapy is that the dose of protons is deposited over a narrow range of depth; hence in minimal entry, exit, or scattered radiation dose to healthy ...
This is typically done if the cancer cannot be removed by surgery. The relief of a blockage can help with pain and difficulty swallowing. Photodynamic therapy, a type of laser therapy, involves the use of drugs that are absorbed by cancer cells; when exposed to a special light, the drugs become active and destroy the cancer cells.
