What should I do if my knees hurt after radiotherapy for nasopharyngeal carcinoma?

Knee pain after radiotherapy for nasopharyngeal carcinoma is a side effect caused by radiotherapy. If radiotherapy is stopped, it can be slowly recovered.

Usually pay attention to a diversified diet, ensure nutritional supply, eat more foods rich in protein and vitamin C, vegetables and fruits, usually do not stay up late, and do not be too tired, so as not to aggravate the condition.

How to treat nasopharyngeal carcinoma metastasis to the lung in the middle and late stages?

How nasopharyngeal carcinoma metastasizes to the lungs in the middle and late stages needs to be determined based on the patient's specific severity of the disease, personal constitution and other factors. It is recommended that patients go to a regular cancer hospital and ask professional doctors to conduct a detailed examination to determine the specific severity of the disease and develop the best treatment plan. Nasopharyngeal carcinoma is a malignant tumor, and early detection and standardized treatment are key. It can metastasize through hemolymph and implantation, which may lead to lung metastasis or other parts.

How to diagnose nasopharyngeal carcinoma and advanced nasopharyngeal carcinoma?

Nasopharyngeal carcinoma patients are asymptomatic in the early stages, but as the disease progresses, nose bleeding may occur in the early stages. As the tumor grows, it may block the posterior nares, and nasal congestion begins as unilateral obstruction and develops into bilateral obstruction. In the early stages of nasopharyngeal carcinoma, the pharyngeal opening of the Eustachian tube may be compressed or blocked, causing ear closure, tinnitus, and hearing loss. In the late stages, headaches and symptoms of cranial nerve damage may occur, such as facial numbness and decreased sense of smell. Nasopharyngeal carcinoma occurs in the posterior nasopharynx. In the late stages, nasal congestion and nose bleeding are common. Tumor invasion into the skull may cause cranial nerve symptoms, such as severe headache, diplopia, and facial numbness. Early diagnosis of nasopharyngeal carcinoma can be achieved through nasal endoscopy combined with nasopharyngeal enhanced CT or nasopharyngeal enhanced MRI.
