You should know that what we presently call “modern medicine” uses tools that have been around for over 150 years. For example, when it comes to tumors, we have new technologies such as MRI, CT, PET scans, etc., to locate and assess the shape of the growth. However, these techniques do not reveal very much about the underlying mechanisms that initiate and lead to progression of the tumor and metastasis. Thus, doctors at this stage use a number of strategies such as drugs, surgery and/or radiation.
Hashem has made us all different, that is, not two people function and react in the same fashion. We are a world of unique characteristics and our individual molecular constitution is always slightly different. Thus, if a drug works for one person, it may not work for the other. Fortunately, cognizant of these drawbacks, scientists are working very hard to “personalize” medicine. In other words, within the next decade, medicine will be customized and based on the patient’s individual profile. The scourge of cancer such as breast, lung and prostate for example, will no longer be classified according to shape, but according to their molecular profile. In fact, scientists will not only be able to predict who will develop any life-threatening condition and prevent it from taking its course before it happens, but will also allow medical professionals to develop new therapies such as drugs which will be more specific and causing fewer side effects than those currently in the market today.
When these medical advances take place, life span of individuals will be as long as trees as was prophesied to Isaiah (Isaiah 65:17-25).
