Learn how to recognize the signs, how veterinarians diagnose and stage the disease, and the latest surgical and medical treatment options.
TL;DR. Jisim biasa dalam tisu kelenjar susu; perlu penilaian doktor haiwan segera kerana ramai yang malignan - terutamanya pada kucing.
Anjing betina mempunyai lima pasang kelenjar susu sepanjang dada dan abdomen.
Apakah itu?
Pertumbuhan abnormal kelenjar susu (rantai sepanjang dada dan abdomen), jinak atau malignan. Sangat biasa pada betina anjing (~50% tumor; kira-kira separuh jinak). Pada kucing betina: tumor ketiga paling biasa, sehingga 80% sangat malignan. Jarang pada jantan.
Punca dan faktor risiko
Didorong hormon reproduktif setiap kitaran birahi. Sterilisasi awal, ideal sebelum birahi pertama, mengurangkan risiko dengan ketara. Mana-mana betina utuh atau disteril lewat berisiko.
Tanda yang perlu diperhatikan
- Jisim susu (utama): nodul tunggal atau beberapa benjolan keras
- Nodus limfa membesar (biasa): ketiak atau groin
- Sakit, ulser atau keradangan (kadang-kadang)
Kecemasan: bengkak pantas seluruh rantai dengan kemerahan dan sakit mungkin karsinoma inflamasi.
Nodul kecil dan keras di bawah kulit ialah tanda awal paling biasa.
Diagnosis
Pemeriksaan, sitologi jarum halus (terhad). Histopatologi selepas pembuangan ialah standard emas. Staging: sinar-X dada 3 paparan, ultrasound abdomen; CT/MRI jika perlu.
"Prognosis for both dogs and cats with malignant tumors is guarded to poor... the major statistically significant survival factor is tumor volume."
Sinar-X dada memastikan tiada merebak ke paru-paru sebelum pembedahan.
Pilihan rawatan
Pembedahan utama. Anjing: lumpektomi atau mastektomi. Kucing: sering mastektomi unilateral lengkap. Kemoterapi jika penyakit lanjut. Karsinoma inflamasi: tiada pembedahan.
Prognosis
Jinak: sembuh dengan pembedahan. Malignan: berjaga-jaga hingga buruk; >3 cm dan metastasis memburukkan survival.
Pencegahan
Sterilisasi awal. Rasa rantai susu setiap bulan; sebarang nodul keras perlu diperiksa segera.
Bila hubungi doktor haiwan
Sebarang jisim susu baharu. Kecemasan jika membesar pantas, ulser, sakit teruk, lesu atau sesak nafas.
