Not so long ago, crippling nausea and vomiting were routine for people undergoing chemotherapy. But thanks to new drugs and other treatments, that isn't the case anymore.
"We've made great progress," says Karen Syrjala, PhD, director of biobehavioral sciences at the Fred Hutchinson Cancer Research Center in Seattle. "We have much less nausea and vomiting now -- even though we're using much higher doses of chemotherapy than we did before." Because we can control the side effects, Syrjala says cancer treatment itself is much more aggressive.
Cartilage is a type of tough, flexible connective tissue (see Question 1).
Cartilage from cows (bovine cartilage) and sharks has been studied as a treatment for people with cancer and other medical conditions for more than 30 years (see Question 2).
Laboratory and animal studies have looked at whether bovine and shark cartilage products can kill cancer cells, make the immune system more active against cancer, and prevent the body from making the new blood vessels that a tumor needs to grow...
Antinausea medications -- or antiemetics -- are so effective, that experts have shifted their focus from treating nausea to its aggressive prevention.
"My standard goal is to stop nausea before it happens," says Christy Russell, MD, chair of the American Cancer Society Breast Cancer Advisory Committee, "rather than waiting for it to start and then treating it."
Of course, not all cases of nausea and vomiting can be prevented -- 70-80% of people on chemotherapy still face some risk. But thanks to better treatment, most people in chemotherapy are able to go about their normal lives, working and caring for their families.
"You may not feel great all the time," says Carmen Escalante, MD, chair of the department of general internal medicine at the University of Texas M. D. Anderson Cancer Center. "But you can keep going. And that's a big improvement on what chemotherapy used to be like."
