Just as for humans, there is no cure for cancer of the uterus in cats. Treatments have been able to save the lives of countless cats, however, depending upon the severity of the cancer.
Benign Tumors: Benign tumors are tumors that are not dangerous yet, but should still be treated by a veterinarian. There are no non-surgical options, but the severity of surgical options varies. Some cases are solved by a simple spaying surgery, which stops the tumors from growing. Other cases may call for a full removal of the uterus to prevent the tumors from worsening or returning.
A spaying surgery is one of the safest possible options with few risks. However, there is no way to be sure that the tumors will not worsen unless the uterus is removed. This surgery is also fairly safe and boasts a low mortality rate. For each of these treatments, the cat should be perfectly healthy after a brief recovery period.
Malignant Tumors: In the case of malignant tumors, the life of the cat is very much in danger. For this reason, veterinarians will routinely remove the uterus and the ovaries from the cat to minimize the risk of any resurgence of cancerous cells. Additionally, many veterinarians recommend chemotherapy after the surgery to ensure that the malignant cells are not transferred to other organs.
Removing the uterus in the case of malignant tumors is just as safe as it is for benign tumors, with an equally brief recovery period afterward. Chemotherapy for cats is not like chemotherapy for humans, as it is only used to improve quality of life. Chemotherapy may continue until either the cancer is completely gone, or until it becomes detrimental to the health of the cat.
