Cancer : Vaccines and Prevention

Vaccines – Vaccines help the body’s immune system prepare for future attacks. Vaccines consist of killed or modified microbes, parts of microbes, or microbial DNA that trick the body into thinking an infection has occurred. A prophylactic vaccination is a selective exposure to a weakened or diluted form of an infectious agent to encourage a patient to form antibodies. Vaccination given during childhood is generally safe.[15] Adverse effects if any are generally mild.[16] The rate of side effects depends on the vaccine in question.[16] Some common side effects include: fever, pain around the injection site, and muscle aches.[16] Additionally, some individuals may be allergic to ingredients in the vaccine.[17] MMR vaccine is rarely associated with febrile seizures.

 Prevention- Cancer chemoprevention is defined as the use of natural, synthetic, or biologic chemical agents to reverse, suppress, or prevent carcinogenic progression to invasive cancer. Screening, in medicine, is a strategy used in a population to identify the possible presence of an as-yet-undiagnosed disease in individuals without signs or symptoms. The effect of diet and nutrition on cancer prevention and recurrence (the return of cancer after treatment) is one of the most studied topics in medicine.
