Chemotherapy or radiotherapy, which is better?

Both are cancer treatments, and are based on the same principle. As cancer cells are continuously dividing and growing, they are very sensitive to damage to their genetic code and the environment in which they grow.

This also damages healthy body tissues that have a high cellular turnover, such as hair and mucous membranes, causing hair loss, nausea and vomiting or ulcers in the mouth and throat, among others.



When is chemotherapy indicated?

Chemotherapy are drugs that are put into a vein or taken by mouth, and their effect reaches the whole body, so it is very effective for the treatment of the disease when it is disseminated (metastasis) or to help shrink the tumor.

What about radiotherapy?

External radiation therapy is ionizing radiation (like x-rays from an x-ray, but at a much higher dose). The radiation beam comes from a CT-like machine and only takes effect where it is administered, so it is very effective for the treatment of localized disease and also metastases, but only on the metastasis that is irradiated.

It is very well understood with an Xej. In a very bulky oral cancer with nodes in the neck, in which the patient has difficulty swallowing and which has a high risk of metastasizing, we could start with chemotherapy to reduce the volume and prevent distant dissemination and then give radiotherapy to eliminate the tumor definitively.


Cancer treatment depends on many factors such as the type of cancer, where it is located, whether it is localized or has metastases, ... And in most cases several combined treatments are used.
