Feline hemangiosarcoma develops in the endothelial cells of blood vessels, making it commonly found in blood vessel-rich organs such as the liver and spleen. This type of cancer tends to metastasize easily through the bloodstream, making it highly malignant and rapidly progressing. However, we believe that implementing immune therapy can improve overall health, maintain quality of life (QOL), and restore appetite and vitality. In fact, there have been numerous cases where feline cancer was controlled through immune strategies using Cordyceps.
This page compiles information regarding the characteristics, treatment methods, and tips for improvement or complete cure of hemangiosarcoma. We also introduce numerous improvement examples. We hope this can be a source of support and a beacon of hope for everyone.
- Hemangiosarcoma is a type of cancer (malignant tumor). In its early stages, there are few symptoms, making it difficult to detect, with some cases suddenly being given a prognosis of six months.
- Treatment methods include surgical intervention and chemotherapy, both of which are considered life-prolonging treatments.
- In cancer treatment, the immune system is extremely important as it can slow down cancer progression and significantly impact the prognosis.

About Feline Hemangiosarcoma
Hemangiosarcoma is a type of cancer (malignant tumor). Due to its development in the endothelial cells of blood vessels, it is commonly found in organs with abundant blood vessels, such as the liver and spleen.
Although it is rarer in cats compared to dogs, it is generally considered extremely difficult to cure or even control, with a very poor prognosis.
Even with surgery or chemotherapy, the life expectancy is thought to be about six months.
In its early stages, there are few symptoms, making it difficult to detect. It is not uncommon for the tumor to rupture and bleed, leading to noticeable changes in health. In severe cases, a prognosis of one month might be given upon discovery.
However, with dedicated efforts, it is possible to coexist with hemangiosarcoma and improve your cat’s prognosis.
We believe that even dogs and cats suffering from hemangiosarcoma can regain their vitality and appetite through proper immune support and live as they naturally should. If your beloved cat is suffering from hemangiosarcoma, please use the information on this page to aim for an improved prognosis for your cat.
General Treatment Methods for Feline Hemangiosarcoma
Surgical Intervention for Hemangiosarcoma
If a tumor (hemangiosarcoma) is localized in one area, surgery may be performed with the hope of extending the pet’s lifespan. Even if the surgery appears successful and the tumor seems to have been completely removed, it is not uncommon for the veterinarian to inform you that “complete recovery is unfortunately difficult,” because cancer cells are highly likely to have metastasized throughout the body.
There are cases where surgery is performed even if it is known that the hemangiosarcoma cannot be completely removed. Such surgeries are called palliative surgeries.
In palliative surgery, the objective is to reduce the tumor’s volume and achieve temporary improvement, but the extent to which lifespan can be prolonged is unclear. Hemangiosarcomas are prone to bleeding from the tumor, and surgery to stop this bleeding can be critically important as an emergency measure.
Chemotherapy for Hemangiosarcoma in Cats
Following surgery, chemotherapy (anticancer drug treatment) is considered. The aim is to target cancer cells that have spread throughout the body and cannot be surgically removed. In cases where the cancer has already spread extensively, chemotherapy alone may be administered without surgery.
Chemotherapy may involve combining anticancer drugs such as doxorubicin (brand name: Adriamycin).
However, hemangiosarcoma is highly resistant to anticancer drugs, so the efficacy of chemotherapy in prolonging life is not certain, even if it puts a strain on the body.
Furthermore, doxorubicin has a side effect that can damage the heart. Therefore, it is a difficult drug to use in pets with heart disease (such as heart failure due to mitral valve insufficiency). If your cat has heart conditions, make sure to discuss the disadvantages thoroughly with your veterinarian.
If you decide to proceed with chemotherapy, using Cordy for immune support and placenta extract from domestic SPF pigs for liver and kidney care can help manage side effects and potentially improve Quality of Life (QOL).

Prognosis, Life Expectancy, and Survival Rates for Cats with Hemangiosarcoma
Generally, the prognosis for hemangiosarcoma is considered very poor.
The survival rate after surgery is said to be about 10% after one year, but successful life extension through surgery is only likely if the cancer is fortunately detected early. There are many cases where the disease has advanced to a stage where surgery is no longer an option. Consequently, the average life expectancy after a hemangiosarcoma diagnosis may be less than three months.
Chemotherapy is considered in hopes of extending life even by a single day; however, its effectiveness is not guaranteed. On the contrary, there is a risk of shortened lifespan and a significant decrease in quality of life (QOL).
Hemangiosarcoma is a highly refractory disease that is largely uncontrollable with conventional treatments alone.
Maintaining QOL and Extending Life with Hemangiosarcoma – The Importance of Immune Improvement
It is recommended to start efforts to enhance immunity immediately after surgery.
In cancer treatment, immunity plays an extremely vital role. It significantly affects the slowing of cancer progression and the overall prognosis. Furthermore, as factors like surgical stress, anesthesia, and the side effects of chemotherapy can easily lower immunity, taking measures to counteract these factors is crucial to prevent worsening the prognosis.
Striving to Extend and Overcome Hemangiosarcoma in Cats
No one is unaffected when diagnosed with hemangiosarcoma. However, brooding over it will not change the situation.
Cancer progresses inexorably over time. If there are benefits, consider surgeries or chemotherapy treatments without delay.
Even if conventional treatments are ineffective, advanced medical treatments and alternative therapies may improve the situation. Please consider Cordy and reviewing your pet’s diet as approaches focusing on immune and nutritional aspects. They can be initiated even while undergoing standard treatments, as they generally do not cause a decline in physical strength or have significant side effects. You can expect improvements in immunity and overall condition with minimal downsides.
There have been reports of pets surviving for 3 years and 7 months with a diet-centered treatment plan. There is also a report of a cat, whose spleen had ruptured and was rushed to a veterinary hospital, showing remarkable improvement and regaining vitality through natural therapies including Cordy.
Please feel free to share your situation with us.
The Power of Immunity for Cats with Hemangiosarcoma
When your beloved cat is diagnosed with hemangiosarcoma, it is crucial to undertake immune support measures regardless of whether they undergo surgery or chemotherapy. Cordy provides immune support without burdening the body.
Although hemangiosarcoma is a cancer that is often resistant to chemotherapy, if you choose to proceed with chemotherapy, you can expect an improvement in the quality of life (QOL) by using Cordy along with domestic SPF pig placenta extract powder for immune and liver support, and krill oil for its anti-inflammatory properties if inflammation is present.
