Shark Cartilage for Cancer

My sister started out with breast cancer and that was supposed to be cured but shortly after she developed a infectious skin cancer. She has had a lot of treatments and nothing seems to be working. I am begging you for some advice on some good herbs for her to take and also any information you may have on shark cartilage we have heard that this may be some new cure for cancer.

Please see previous answers to questions on cancer on our website at www.richters.com, and then go to the "Q&A" area and search for "cancer".
Shark cartilage is being promoted for cancer prevention and treatment. Research studies have shown that it works in some cases. It is usually used as the sole therapy - not with chemotherapy or radiation.
