Why monitoring mast cell tumors is challenging

Mast cell tumors can swell, shrink, or change appearance, making it hard to judge progress from memory alone.

Dogs may be on several medications, and keeping doses straight across weeks is easy to lose track of.

Subtle symptoms like vomiting or a flushed lump can matter, but only if you notice the pattern over time.

Frequently asked questions

How often should I measure my dog's lumps?
Measuring on a consistent schedule, such as weekly, makes changes easier to spot than occasional checks. The app helps you keep a steady record, while your veterinarian advises how closely to monitor a given tumor.
What changes in a lump should I report?
Sudden growth, redness, swelling, or a lump that flares and shrinks can be worth flagging. Logging measurements and photos helps you describe these changes accurately to your vet.
Why do mast cell tumors sometimes swell suddenly?
These tumors can release substances that cause local swelling or redness, which is one reason tracking appearance matters. Share your notes with your veterinarian, who can interpret what they mean.
Can I track several lumps separately?
Yes. Keeping a separate record for each lump's size and location helps you and your vet follow multiple sites without confusing them.
Does this app diagnose or treat tumors?
No. PetHealthLog only helps you organize observations. Mast cell tumors require professional diagnosis and treatment, so always work with a licensed veterinarian.
