Cancer in cats is a significant health concern, particularly for older cats. Here are some key points about the prevalence and impact of cancer in cats:

患病率：

• Commonality: Cancer is one of the leading causes of death in older cats. It’s estimated that about 1 in 5 cats will develop cancer in their lifetime.
• Age Factor: The risk of cancer increases with age. Most feline cancers are diagnosed in cats over 10 years old.

Common Types of Cancer in Cats:

• 淋巴瘤: This is the most common type of cancer in cats, affecting the lymphatic system. It can occur in various forms, including gastrointestinal lymphoma, which is prevalent in older cats.
• Squamous Cell Carcinoma (SCC): This skin cancer often affects the mouth, ears, and nose, particularly in cats with lighter skin.
• 乳腺腫瘤: These are more common in female cats, especially those that are unspayed. Approximately 85% of mammary tumors in cats are malignant.
• 纖維肉瘤: This cancer affects the connective tissues and is sometimes associated with injection sites (injection-site sarcomas).

Symptoms and Impact:

• 減肥: Unexplained weight loss is a common symptom of cancer in cats.
• Appetite Changes: Cats may lose their appetite or become picky eaters.
• Lumps and Bumps: Any new lumps or bumps should be evaluated by a veterinarian.
• 行為改變: Cats with cancer may become more lethargic, less playful, or show signs of pain.
• Vomiting and Diarrhea: These symptoms can be associated with gastrointestinal cancers.
• Breathing Difficulties: Respiratory issues can arise from cancers affecting the lungs or other parts of the respiratory system.

診斷：

• 獸醫檢驗: Regular veterinary check-ups are crucial for early detection.
• 診斷測試: Blood tests, X-rays, ultrasounds, and biopsies are commonly used to diagnose cancer in cats.

治療：

• 手術: Often used to remove localized tumors.
• 化療: Can be effective, particularly for lymphoma. Cats generally tolerate chemotherapy better than dogs and humans.
• 放射治療: Used for certain types of cancers like SCC.
• 安寧療護: Focuses on managing symptoms and maintaining quality of life, especially in advanced cases.

Holistic and Supportive Care:

• Diet and Supplements: Nutritional support and supplements may help improve a cat’s overall health and well-being.
• 疼痛管理: Pain relief is an important aspect of care for cats with cancer.
• 替代療法: Some pet owners explore herbal remedies and other holistic treatments to support their cats’ health.

預後：

• The prognosis for cats with cancer varies widely depending on the type, location, and stage of the cancer, as well as the cat’s overall health. Early detection and treatment can improve the chances of a positive outcome.

Regular veterinary check-ups and being vigilant about any changes in your cat’s health are essential for early detection and effective management of cancer.
