How long is a course of radiotherapy?
VerifiedDedicated to your well-being.
The course of radiotherapy usually lasts for 3~8 weeks, but the specific course of treatment depends on many factors such as the age and sensitivity of the lesion. For
radical radiotherapy with relatively early lesions and radiotherapy as the main treatment method, the course of treatment is usually 5~7 weeks. For palliative radiotherapy with late lesions, the course of treatment is usually 3~5 weeks.
The sensitivity of the tumor also affects the duration of radiotherapy. For more sensitive tumors, such as lymphoma, the radiotherapy duration is generally shorter, about 3 to 5 weeks. For less sensitive tumors, such as fibrosarcoma, the radiotherapy duration may take 6 to 8 weeks.
Preoperative radiotherapy is intended to improve the surgical resection rate and reduce recurrence, generally 4 to 5 weeks. Postoperative radiotherapy is usually performed for 5 to 6 weeks in order to reduce postoperative metastasis and recurrence. For elderly patients or patients with other chronic diseases, the radiotherapy time may be shortened accordingly, generally about 5 weeks.
Since the radiotherapy time varies under different circumstances, it is recommended to consult a doctor before formulating a treatment plan. The doctor will develop a personalized treatment plan based on the specific situation of the patient to ensure the effectiveness of the treatment and minimize side effects.
