How long can I live without treatment for advanced brain cancer?

What are the final symptoms of a brain tumor?

Before dying, the patient may show the following signs: deep coma, no response to any stimulation, bilateral dilated pupils, no light reflex, late stage symptoms include headache, abnormal sensation or movement, numbness or limited movement of one limb, hemiplegia, aphasia, blindness, etc., and severe symptoms include nausea and vomiting. It is suggested that patients with advanced brain tumors should relax and not put too much psychological pressure on themselves. For patients with brain tumors, brain herniation is the most common cause of death.

Can targeted drugs make brain tumors disappear?

Targeted drugs are mainly used for the treatment of advanced tumors. In most cases, they shrink the tumor, and most of them cannot cure the disease. Since targeted drugs are directed at a certain target, not all patients can take them. You must have a corresponding target to take the corresponding targeted drug. Moreover, targeted drugs will sooner or later develop drug resistance. As tumor cells gradually evolve, resistant cells will survive. Therefore, all targeted drugs can only control the disease for a period of time. After a certain period of time, drug resistance may occur, and there may be new developments.

Therefore, after drug resistance develops, genetic testing is often required to see if there are new targeted drugs that can be used, or to switch to radiotherapy or chemotherapy to control the tumor. Confirmed brain cancer, especially brain metastasis cancer, needs to consider genetic testing to select targeted drugs. Targeted drugs are drugs that specifically treat brain metastasis cancer. If there is a suitable targeted drug option, the treatment effect is often better than chemotherapy drugs.
