Metastatic Brain Tumor: Causes, Symptoms, and Treatment

What kind of doctor treats Metastatic Brain Tumor?
A neurologist, a doctor who treats problems of the brain and nervous system, often helps manage these tumors. Care usually involves a team that may include a neurosurgeon, a radiation oncologist, and a medical oncologist. A regular doctor helps coordinate everything.
What it is
A metastatic brain tumor is a growth in the brain that started as cancer somewhere else in the body and then spread. These tumors are much more common than tumors that start in the brain itself. Cancer cells usually reach the brain through the blood.
Symptoms
Symptoms depend on where the tumor is and how big it is. Common signs include headaches that may be worse in the morning, seizures, and weakness or numbness on one side of the body. Other signs include trouble speaking, vision changes, balance problems, confusion, personality changes, nausea, or vomiting.
Causes and who gets it
These tumors happen when cancer cells break away from a tumor elsewhere and travel to the brain. The cancers most likely to spread to the brain are lung cancer, breast cancer, melanoma, and kidney cancer. Adults are far more likely than children to get them, and the risk rises with age.
How doctors diagnose it
Doctors start with a physical exam and the main test is an MRI, a scan that makes detailed pictures of the brain. Sometimes a CT scan is used instead. Doctors may order more imaging to find where the cancer started, or take a tissue sample called a biopsy.
Treatment
Treatment depends on the type of cancer, the number of tumors, where they are, and the person's overall health. Options often include surgery, radiation therapy, and medicines such as targeted drugs or chemotherapy. Doctors may also prescribe steroids to reduce brain swelling and medicines to control seizures. Many people get a combination of treatments.
When to see a doctor
Anyone with cancer who gets new headaches, seizures, weakness, confusion, or vision changes should contact a doctor right away. A sudden, severe headache, a first seizure, or trouble speaking also needs urgent attention. Early treatment can help manage symptoms.
How a direct primary care or concierge doctor fits in
A direct primary care doctor charges a flat monthly fee instead of billing insurance; a concierge doctor usually costs more and often works alongside insurance. These doctors can manage symptom-controlling medicines and spend extra time answering questions. They do not perform surgery or give radiation, so they refer patients to specialists and help coordinate appointments among the care team.
Common questions
Are metastatic brain tumors always cancer?
Yes. By definition, a metastatic brain tumor is cancer that spread from another part of the body. Not all brain growths are cancer, though, which is why testing matters.
Can a metastatic brain tumor be cured?
Some people are treated successfully and live for years, especially when there is only one tumor that can be removed. Outcomes vary a lot, and a care team can give a picture of what to expect in a specific case.
Is a metastatic brain tumor the same as brain cancer that starts in the brain?
No. A tumor that starts in the brain is called a primary brain tumor. A metastatic tumor started somewhere else, such as the lung or breast, and traveled to the brain.
