Cancer research is the scientific study aimed at understanding how cancer develops, spreads, and can be treated. Scientists investigate the genetic and environmental factors that contribute to different types of cancer, such as breast cancer or lung cancer. This research helps in discovering new ways to prevent, diagnose, and treat the disease, ultimately improving patient outcomes. Advancements in cancer research have led to innovative treatments like immunotherapy and targeted therapies, which focus on specific characteristics of cancer cells. By collaborating with hospitals and research institutions, scientists can share findings and develop clinical trials, providing hope for better therapies and a potential cure for cancer in the future.
