Chemotherapy

A representation of Chemotherapy

Chemotherapy is a treatment method that kills cancer cells or slows down their growth. It is often used when the cancer has spread in the body or when other therapies are not sufficient. Chemotherapy can also improve the quality of life and life expectancy of dogs with cancer.

What is chemotherapy?

Chemotherapy is the use of drugs that act against cancer. These drugs are also called cytostatics because they inhibit or stop cell division. Most cytostatic drugs not only affect cancer cells, but also healthy cells that divide quickly, such as blood, hair or intestinal mucosa cells. This can lead to side effects such as nausea, vomiting, hair loss or diarrhea.

How is chemotherapy used in dogs?

Chemotherapy can be administered to dogs in various ways:

  • As an injection into a vein, muscle or under the skin
  • As a tablet or capsule to swallow
  • As an ointment or cream to apply to the skin
  • As an inhalation through the nose or mouth

The method of administration depends on the type of cancer, the stage of the disease and the general condition of the dog. The dose and frequency of treatment are adjusted individually. Chemotherapy can be used as a stand-alone therapy or in combination with other treatments such as surgery, radiotherapy or immunotherapy.

What are the benefits and risks of chemotherapy in dogs?

Chemotherapy can have the following benefits for dogs:

  • It can slow or stop tumor growth
  • It can reduce or eliminate pain
  • It can increase quality of life and life expectancy

Chemotherapy can have the following risks in dogs:

  • It can cause side effects such as nausea, vomiting, hair loss or diarrhea
  • It can weaken the immune system and increase the risk of infections
  • It can lead to anemia or bleeding
  • It can impair fertility or cause undesirable changes in the genome

Most side effects are temporary and can be treated with medication. The severity and duration of side effects depend on the type, dose and frequency of chemotherapy. Not all dogs react to chemotherapy in the same way. Some dogs have hardly any side effects, while others are more severely affected.
