Conventional cancer immunotherapies: assessing progress and envisioning future possibilities

Cancer immunotherapy aims to modify and improve the immune systems’ fight against cancer, it is a highly promising and evolving field. It is effective at treating a wide range of cancers, suppressing tumor growth and improving survival rate of cancer patients. Despite the promise and fervor around cancer immunotherapy, many challenges have limited their widespread use and efficacy. In this review article, we consider novel cancer immunotherapies, encouraging clinical trials and innovative strategies employed in developing safe and effective cancer immunotherapies. It is safe to say that cancer immunotherapy has revolutionized cancer therapy, but there are hurdles and challenges (toxicity concerns being the most notable) that must be overcome for safer and more effective treatment strategies. The battle against cancer is an arduous and prolonged affair. We aim to point out what we have achieved in recent times and outline potential strategies to mitigate our losses and chart a course of victory.
