When to consider a second opinion for brain tumors
This page is general information, not a diagnostic tool.
Having one of the signals below does not mean you have brain tumors — most causes of most symptoms are not cancer. Nothing here can or should be used to diagnose yourself or anyone else.
Persistent or worsening symptoms should always be evaluated by a doctor in person. OncologyIstanbul's own role begins after that — once you already have a diagnosis, test results, or a specific medical concern a doctor has raised — coordinating a free 72-hour tumor-board second opinion in Istanbul. We do not diagnose, and this page is not trying to.
Every cancer case is individual. Assessments are based on the reports you provide and do not replace in-person examination. Survival statistics are population-level data, not personal predictions.
Headaches, dizziness, and similar symptoms are common and are almost always caused by things other than a brain tumor — tension, migraine, dehydration, viral illness. The signals below are worth a doctor's attention mainly when they're new, persistent, or represent a real change from your usual pattern.
Reasons a second-opinion conversation makes sense
- New, persistent headaches with a different pattern than your usual headaches — especially if worse in the morning or with straining
- A new seizure, or unexplained changes in vision, speech, balance, or coordination
- Persistent nausea or vomiting without an obvious digestive cause
- Noticeable changes in memory, personality, or alertness — particularly if others have pointed it out
This is a short, standard list of well-established reasons to see a doctor — not an exhaustive checklist. A symptom not listed here can still be worth discussing with a doctor, and having one of these signals is far more often explained by something other than cancer.
That's exactly when OncologyIstanbul can help — a free 72-hour tumor-board second opinion from named Istanbul specialists, with an itemized price quote if treatment is indicated.
