Neuro-oncology is a special area of medicine that deals with growths (also called tumours) found in the brain and along the spinal cord. These growths can be either harmless (not cancerous) or harmful (cancerous). This guide offers simple information about these conditions, what signs to look for, how doctors find them, and the different ways they can be treated.
How Brain and Spinal Cord Tumors Develop?
Brain and spinal cord tumors form when certain cells grow out of control. These abnormal cells group together to create a mass or growth. Tumors can start in the brain or spine (primary tumors) or spread from other parts of the body (secondary or metastatic tumors).
Why this happens isn’t always clear, but changes in genes, family history, or exposure to radiation may increase the risk. Some tumors grow slowly, while others can grow quickly and press on nearby nerves or tissues, leading to serious symptoms. “Low-grade” growths are slower, while “high-grade” ones grow faster.
Noticing the Signs
Symptoms can vary a lot depending on the growth’s location, size, and speed.
Common signs of brain growths:
- Headaches (often worse in the morning or with activity).
- Seizures.
- Ongoing nausea or vomiting.
- Changes in personality, memory, or focus.
- Weakness or numbness on one side of the body.
- Problems with balance, vision, or speech.
Signs of spinal cord growths:
- Lasting back pain, possibly spreading or worse at night.
- Numbness, tingling, or weakness in arms or legs.
- Trouble with bladder or bowel control.
- Difficulty walking.
If you have new, persistent, or worrying signs, see a doctor. Early discovery can lead to better results.
How Doctors Find These Growths
A doctor will likely do a nerve check-up (vision, balance, strength). If a growth is suspected, picture-taking tests are key.
Main diagnostic tools:
- MRI: Uses magnets for detailed brain/spine pictures.
- CT Scan: Uses X-rays for cross-sectional images.
- Biopsy: A small tissue sample is examined to confirm the type of growth.
- Special Tissue Tests: Check for genetic markers to guide treatment.
Treatment Options
Treating these growths involves a team of specialists, including brain tumour doctors, surgeons, and radiation experts. Your treatment plan is personalised.
Common treatments:
- Surgery: Often the first step is to remove as much of the growth as safely possible.
- Radiation Therapy: Uses high-energy rays to target growth cells.
- Chemotherapy: Uses drugs to destroy growth cells.
- Targeted Therapy: Drugs that attack specific features of cancer cells.
- Immunotherapy: Boosts your body’s immune system to fight cancer.
- Tumour Treating Fields: A wearable device for some brain cancers that uses electrical fields.
Steroids can reduce swelling. Therapies for movement, daily tasks, and speech can help with recovery.
Conclusion
A diagnosis can be overwhelming, but today’s treatments offer hope. Early detection, personalised care, and a dedicated medical team can improve outcomes and quality of life. Living with such a growth is challenging, but experts, research, and supportive care provide hope.
