Grape Seed Extract and Angiogenesis
For cancer to survive in the body it needs to start, grow, and it needs to be supplied with nutrients and then it can spread. These processes of creating a blood supply for the tumor is called angiogenesis. Angiogenesis not only supplies the tumor with a blood supply but also supports the spread of cancer via the blood stream.
For a cell to survive and thrive, it needs the nutrients to support cellular function. As tumors grow bigger, they need new blood vessels to be formed to continue to feed the tumor. Compounds that can prevent the formation of these new blood vessels can be extremely helpful in treating the disease.
According to a study published in the International Journal of Cancer, researchers showed that the compounds in grape seed extract offered anti-angiogenesis properties. In essence, grape seed extract prevented the tumor from creating new blood vessels to help fuel the growth of the tumor.
Grape Seed Extract and Apoptosis
Apoptosis is a fancy medical term for programmed cell death. Every cell in your body is designed to commit suicide at a certain time. Cancer cells differ from normal cells because something has interfered with that process. Cancer cells therefore live longer than normal cells and this is the mechanism that allows tumors to grow and flourish.
Grape seed extract has the ability to target colorectal cancer cells and to induce apoptosis in those cells only.
This means that grape seed extract triggers suicide in the cancer cells and leaves healthy cells intact. Very few, if any, chemotherapy regimens have the ability to do this. Most chemotherapy drugs kill all cells including healthy cells. This effectively means grape seed extract is less destructive in its application than conventional chemotherapy.[4]
Grape Seed Extract and Advanced Stages of Colorectal Cancer
The more advanced the cancer, the less chance there is that chemotherapy will be effective at treating colorectal cancer. Once again, grape seed extract offers hope for those patients diagnosed with advanced stage of colorectal cancer.
In the Technologies in Carcinogenesis and Cancer Chemoprevention study mentioned above, scientists not only showed that grape seed extract targeted colorectal cancer cells and killed them, but also proved that the more dangerous and advanced the cancer cells were, the more effective the grape seed extract seemed to be in terms of isolating and killing the cancer cells.[5]
Grape Seed Extract Offers Hope for Other Types of Cancer
The ability of grape seed extract to help prevent and treat colorectal cancer may sound too good to be true, but there is more. Grape seed extract is not only effective for colorectal cancer but may be effective in various other types of cancer too.
- Grape seed extract was shown to hinder tumor growth in prostate cancer[6]
- Grape seed extract may play a role in breast cancer[7]
- Grape seed extract may induce cancer cell death in leukemia[8]
- Grape seed extract may play a role in reducing the spread of oral cancer[9]
Grape Seed Extract Offers Real Hope
We like to believe that mainstream medicine has all the answers but it often lets us down. Mother Nature offers a myriad of amazing plants and other herbal extracts that can offer some hope where there seems to be none.
Grape seed often comes in standardized extracts with certain levels of proanthocyanidins (powerful antioxidants). It is recommended to look for products that are standardized to 40 to 80% or an OPC content of not less than 95%[10] (like this one or like this one). Speak to your doctor to find the right dose for your condition.
