Get started in under a minute
Measure and log each lump's size and location, adding photos when appearance changes.
Record every medication dose and any symptoms like vomiting or low energy.
Export your monitoring history before vet visits so your veterinarian can assess changes over time.
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.

When to contact a vet immediately
A tracker is for patterns over time — it is not for emergencies. Contact a veterinarian or an emergency clinic right away if your pet has difficulty breathing, collapses or cannot stand, has a seizure that does not stop or seizures that repeat, is straining to urinate without producing urine, has severe bleeding, or may have swallowed something toxic (see ASPCA Animal Poison Control).
PetHealthLog is a record-keeping tool, not veterinary advice. Nothing on this page diagnoses or treats any condition — always follow your own veterinarian's guidance.
