Is it bad that i got the cancer prevention shot and i'm self medicating with drugs like hormone replacement i get them online and i buy the injections?

Bad to self-medicate: Unless a person is a trained physician, he or she cannot be buying stuff online and self-treating, regardless of whether the stuff is injectable or not. It's a very bad idea. Cancer-prevention shots such as the Hepatitis B vaccine or the Human Papilloma Virus vaccine are available at doctor's offices and at public health clinics.
