In the long term, overweight and obesity in children increase the risk of obesity, diabetes, heart disease, some cancers, respiratory disease, mental health, and reproductive disorders later in life. The laboratory study used human cell samples to investigate the mechanism behind how breast cancer tumors develop resistance to treatments, effectively making them powerless. These activities work well in unison with textbook lessons on immunity.
