What should you know about canine vulvar cancer?

The phrase can be confusing because canine disease belongs in veterinary care. If your concern is about your own vulva, use human cancer information and arrange an examination rather than applying advice written for dogs.

In people, vulvar cancer begins in tissues of the external genital area. A clinician assesses a persistent lump, sore, skin change, bleeding, pain or itching by examining the area; a tissue sample may be needed to identify the cause. These changes can have non-cancerous explanations, so the symptom alone does not establish a diagnosis.

In a dog, a vulvar mass or change also needs direct examination, but diagnosis, staging and treatment are managed by a veterinarian. Human and veterinary treatment plans are not interchangeable, even when similar words such as surgery or radiotherapy are used.

For a human concern, book an appointment with a gynaecologist or primary-care clinician and describe when the change began, whether it is worsening, and whether there is bleeding, discharge, itching or pain. Avoid using leftover creams or veterinary medicines on the area because they can irritate tissue or obscure the examination.

For a dog, contact a veterinary clinic and note changes in licking, urination, discharge, bleeding, appetite or activity. Prevent the dog from repeatedly traumatising the area if this can be done safely, and do not give human pain medicines unless a veterinarian has prescribed them.

A person should seek prompt medical assessment for a new or persistent vulvar lump, ulcer, unexplained bleeding, changing patch of skin, or symptoms that do not settle. Urgent care is appropriate for heavy bleeding, severe or rapidly worsening pain, faintness, fever with marked illness, or difficulty passing urine.

A dog needs urgent veterinary attention for uncontrolled bleeding, inability to urinate, collapse, severe distress or rapidly increasing swelling. Otherwise, arrange a timely veterinary visit for a visible mass, persistent discharge, recurrent bleeding or ongoing licking.

Ask what examinations or tissue tests could identify the change, whether imaging is needed, and who will explain the results. If cancer is confirmed, ask about the treatment goal, whether tumour-removal surgery or radiotherapy is suitable, expected effects on urination and wound care, and which symptoms should trigger an urgent call.
