At present, various marine drugs extracted from marine organisms have shown unique efficacy in cancer prevention and treatment. Seaweed such as kelp, laver and Undaria pinnatifida all have certain anticancer effects. Seaweed contains many trace elements, especially iodine, and its organic iodine is absorbed and excreted slowly in the body, which is quite effective in preventing cancer.

Kelp not only contains nutrients such as protein, fat and minerals, but also can selectively filter out carcinogens such as strontium and cadmium. At the same time, because the cellulose contained in it is not easy to be digested, it can increase the amount of stool, promote the excretion of some carcinogens in the body, and contribute to cancer prevention and health care.

Marine fish contains anti-cancer fitness substances. For example, some substances in cod liver oil have a certain inhibitory effect on tumor necrosis factor (TNF) and leukocyte stroma produced by white blood cells. Proper consumption of cod liver oil is not only beneficial to the elimination of human inflammation, but also can improve human urination function and reduce impurities in blood.

Shark cartilage contains a factor that inhibits tumor angiogenesis, so it can inhibit tumor growth. Squalene isolated from shark liver has good anticancer effect and low toxicity. Active ingredients such as osmotic adjustment protein, Stichopus Japonicus glycoside and acidic mucopolysaccharide contained in sea cucumber also have the functions of anti-cancer and inhibiting cancer cell metastasis.
