The predictions are that over the next several years, cancer research will only become stronger. Already we are gaining a lot more of an understanding regarding what causes tumors, how they grow, how they survive and/or resist the drugs that we have found should treat them. We also know that specific proteins can slow down their growth and development.
Therefore, in the future, it stands to reason that we will be able to continue our knowledge and find a better cure to fight cancer. Doctors will be able to have access to targeted therapies and immune therapies that will enable your body to fight off cancer. There may even be a vaccination that can prevent it from being a problem.
However, even then, early detection is the key to success. If you wait until your symptoms are severe, you will be risking your own health.
