I will redo both PET and MRI scans in three weeks but my mouth is really starting to hurt - what can I do to accelerate treatment if it is cancer
Important First Step
Before assuming this is cancer recurrence, it's critical to identify what's causing the pain. Oral pain during surveillance can have many causes:
- Post-treatment tissue changes or scarring
- Oral mucositis (inflammation of mouth tissues)
- Infection (fungal, bacterial, or viral)
- Dental issues
- Radiation-related complications
- Temporomandibular joint (TMJ) problems
- Neuropathic pain from previous treatment
Getting a diagnosis of the pain itself is the first step.
What You Can Do NOW (Before Imaging Results)
1. Contact Your Oncology Team Immediately
- Don't wait 3 weeks if pain is significant
- Describe: location, severity (1-10 scale), when it started, what makes it better/worse
- Ask for urgent evaluation—they may want to see you sooner
2. Symptom Management
- Topical relief: Oral anesthetics (benzocaine), salt water rinses, ice chips
- Pain management: Over-the-counter options (acetaminophen, ibuprofen) or prescription options your doctor recommends
- Oral care: Soft toothbrush, alcohol-free mouthwash, avoid irritating foods
- Nutrition: Soft foods, smoothies, protein supplements if swallowing is difficult
3. Specialist Evaluation
- Ask your oncology team if you need to see: oral surgeon, dentist, speech pathologist, or pain management specialist
- They can identify the specific cause of pain
If Cancer IS Confirmed
According to NCCN Guidelines for Head and Neck Cancers, treatment decisions depend on:
- Location and extent of recurrence
- Previous treatments you've received
- Time since original treatment
- Your overall health status
Options may include surgery, radiation, chemotherapy, or combinations—but your team determines this based on your complete clinical picture.
Questions to Ask Your Team RIGHT NOW
- "Can I be seen sooner than 3 weeks given this pain?"
- "What could be causing this pain besides cancer recurrence?"
- "Should I see a specialist (oral surgeon, dentist, pain management) while waiting for imaging?"
- "What pain management options are safe for me given my treatment history?"
- "If imaging confirms recurrence, what would treatment look like, and how quickly would we start?"
Reality Check
Accelerating treatment before you have a diagnosis isn't possible—and it's important to know what you're treating. Your imaging in 3 weeks will give you answers. In the meantime, managing pain and getting evaluated for its cause is the right focus.
Don't suffer unnecessarily while waiting. Call your oncology team today about the pain.
