Shark has been living on the earth for more than 40 billion years, and as a very old creature, it’s famous for its brutal. Do you know that shark can not only be good for the oceanic ecological balance but can also be beneficial for humans. In recent years，the shark cartilage has given greatness to humans. Scientists found that sharks have high-resistance capability, rarely get sick and even not afraid of infection. What's surprising is even if you put a shark into water that contains numerous carcinogens, or feed it with carcinogens, it will still remain healthy. It is speculated that there’s something inside a shark that have antitumor mechanism or a strong immune system that can For that reason, some countries did a lot of research, and then found out that there’s something to do with the shark cartilage. The protein in shark cartilage has powerful inhibition effects to Neovascularization, which means if we want to prevent angiogenesis that could prevent cancer.
The anticancer actions of shark cartilage can be divided into three parts: cancer cell cytotoxicity, stimulates the immune system and anti-angiogenesis. How the first two works is still unknown, but there are a lot of reports about anti-angiogenesis. Because cancer cells can’t get enough blood to keep alive, they can’t grow.
Shark cartilage doesn’t have any vascular system; the cartilage has active ingredients like four kinds of biologically active proteins, chondroitin sulfate and polysaccharide etc. The growth and metastasis of malignancy, rely on angiogenesis, so it can get nutrient. If the malignancy’s vasoganglion has been destroyed, then the growth and metastasis of malignancy will be stopped.
According to this, scientist made supplements like shark cartilage, and has been widely used in clinic and can bring results. In 1992, a doctor from Cuba gave shark cartilage products to 29 terminal-cancer patients, and 14 of them were cured. An American doctor gave shark cartilage products to 110 terminal-cancer patients, and just after a few weeks, most of the patients’ tumors shrink, and 15 of them don’t have tumors any more. In 1994, FDA had approved shark cartilage products to be used in preventing cancer. Therefore, shark cartilage has become a hot spot in the market and affects the whole world.
