Brain metastasis: surgery, radiosurgery or systemic treatment
Reviewed on July 17, 2026
Learning that a cancer has reached the brain is one of the hardest pieces of news to receive, and feeling afraid is natural. Even so, there have been major advances in treating brain metastases, and today several options can control the disease and preserve quality of life. Understanding these choices helps you face this moment with more clarity, always supported by a dedicated multidisciplinary team.
What brain metastases are
Brain metastases are tumors that originate from a cancer elsewhere in the body, such as lung, breast, skin (melanoma) or kidney, and spread to the brain. They may be single or multiple and vary widely in size and location.
Symptoms depend on where they are and may include headaches, weakness, speech changes, behavioral changes or seizures. They are often detected on scans done to follow the original cancer.
Surgery and radiosurgery
Surgery may be recommended when there is a larger, symptomatic or easily accessible lesion, especially to relieve pressure and obtain tissue for diagnosis. Radiosurgery, a very precise form of radiation therapy, treats small or multiple lesions without incisions, while sparing the surrounding healthy brain.
In many cases, surgery and radiosurgery complement each other. The choice depends on the number, size and location of the lesions, as well as symptoms and overall health.

Request a second opinionSystemic treatment
Therapies that act throughout the body, such as chemotherapy, targeted therapies and immunotherapy, play a growing role. Some modern drugs can cross the blood-brain barrier and act directly on brain metastases, depending on the cancer type and its markers.
Systemic treatment is often combined with local therapies, and the plan is adjusted according to the response. The decision involves the neurosurgeon, oncologist and radiation oncologist, always considering your goals.
Why a second opinion helps
For brain metastases, the options have changed greatly in recent years, and an independent second opinion can ensure you have access to the most current approaches. It helps confirm staging, review whether surgery, radiosurgery and systemic therapies were all considered and check that the plan is well coordinated.
Seeking another view is common and encouraged in this setting. A careful review by an independent specialist can confirm the proposed path or suggest adjustments, helping you and your family decide with greater confidence and calm.
